How many levels can a domain name have? What are generic top-level domains?

Answers

Answer 1

A domain name can have multiple levels, and generic top-level domains (gTLDs) are a specific category of domain extensions.

How many levels can a domain name have?

A domain name consists of multiple levels, separated by dots. The highest level is the top-level domain (TLD), which typically represents the purpose or geographical location of the website.

Examples of TLDs include .com, .org, and .net. Below the TLD, additional levels can be added to create subdomains.

These subdomains can represent different sections or departments within a website. For example, "blog.example.com" has two levels, with "com" as the TLD and "example" as the subdomain.

The minimum number of addition operations required to make A as palindrome is obtained by taking the sum of the absolute differences between the left and right halves of the array. A palindrome is a string that reads the same forwards and backwards.

A palindrome number is a number that reads the same forwards and backwards. We need to find the minimum number of addition operations required to make the input array a palindrome. We are given an array A and the output is the array after performing the addition operation if possible. We can add adjacent two elements only.The input format consists of the number of elements in the array and the subsequent lines accept the elements of the array. The output format is the output array.

If such addition operations are not possible, then output * as there is no such palindrome array.To solve this problem, we can calculate the absolute difference between the left half and the right half of the array. If the difference between the left half and the right half is greater than one, we cannot make it into a palindrome with only adjacent additions. So, the answer is *. If the difference is less than or equal to one, we can make it into a palindrome with the minimum number of adjacent additions required to make the difference zero.

What is IPsec? Describe the different phases of IPsec

Answers

IPsec is a network protocol suite that provides secure communication over IP networks.

IPsec, short for Internet Protocol Security, is a set of protocols and algorithms that ensure secure communication over IP networks. It provides a framework for authenticating and encrypting IP packets, thereby protecting the confidentiality, integrity, and authenticity of network traffic. IPsec operates at the network layer of the OSI model, enabling secure communication across a wide range of network topologies.

The IPsec protocol suite consists of two main components: the Authentication Header (AH) and the Encapsulating Security Payload (ESP). AH provides authentication and integrity checks for IP packets, ensuring that they have not been tampered with during transmission. ESP, on the other hand, offers encryption and authentication services, protecting the confidentiality and integrity of the packet contents.

IPsec operates in two modes: transport mode and tunnel mode. In transport mode, only the payload of the IP packet is encrypted and authenticated, while the original IP header remains intact. This mode is typically used for end-to-end communication between two hosts. In tunnel mode, the entire IP packet, including the original IP header, is encapsulated within a new IP packet. This mode is commonly used for secure communication between two networks.

The IPsec protocol operates in two main phases: Phase 1 and Phase 2. Phase 1 establishes a secure channel between two IPsec peers by negotiating security parameters, such as encryption algorithms and keys. This phase involves an initial key exchange, usually based on the Internet Key Exchange (IKE) protocol. Once Phase 1 is complete, Phase 2 establishes the actual IPsec security associations, which define the specific security policies and algorithms to be used for protecting the IP traffic.

add 896 (base 10) & 357 (base 10) using BCD approach

Answers

The sum of 896 (base 10) and 357 (base 10) using the BCD approach is 1253 (base 10).

Binary-coded decimal (BCD) is a method of representing decimal numbers using a four-bit binary code for each decimal digit. In the BCD approach, we add the corresponding BCD digits from right to left, just like in normal addition. If the sum of a BCD digit pair is greater than 9 (which is the maximum value for a BCD digit), we carry over to the next higher BCD digit.

Adding the ones (least significant) digit

The BCD representation of 6 is 0110, and the BCD representation of 7 is 0111. Adding these BCD digits gives us 1101, which is the BCD representation of 13. Since 13 is greater than 9, we carry over the 1 to the next higher BCD digit.

Adding the tens digit

The BCD representation of 9 is 1001, and the BCD representation of 5 is 0101. Adding these BCD digits, along with the carry-over from the previous step, gives us 1111, which is the BCD representation of 15. Again, since 15 is greater than 9, we carry over the 1 to the next higher BCD digit.

Adding the hundreds (most significant) digit

The BCD representation of 8 is 1000, and the BCD representation of 3 is 0011. Adding these BCD digits, along with the carry-over from the previous step, gives us 1011, which is the BCD representation of 11. Since 11 is not greater than 9, there is no carry-over in this step.

Combining the BCD digits from the three steps, we get 1101 for the ones digit, 1111 for the tens digit, and 1011 for the hundreds digit. Converting these BCD digits back to decimal form gives us 1253, which is the final result.

To retrieve the airport fee based on the fee schedule in the Fees worksheet, use the VLOOKUP function in cell L3 of the Requests worksheet. Copy the formula down to cell L6.

The VLOOKUP function in Microsoft Excel is a powerful tool for searching and retrieving specific values from a table. In this case, we are using it to retrieve the airport fee based on the fee schedule in the Fees worksheet.

To implement this, follow these steps:

1. In the Requests worksheet, select cell L3 where you want to display the airport fee.

2. Enter the following formula: "=VLOOKUP(discounted_fare, Fees!A:B, 2, FALSE)".

Now, let's break down the formula and understand its components:

- "discounted_fare" is the value we want to match in the fee schedule. This could be the cell reference to the discounted fare value in the Requests worksheet.

- "Fees!A:B" refers to the range of cells in the Fees worksheet where the fee schedule is located. Column A contains the values to match against, and column B contains the corresponding airport fees.

- "2" specifies that we want to retrieve the value from the second column of the fee schedule, which is where the airport fees are listed.

- "FALSE" ensures that an exact match is required for the VLOOKUP function to return a value.

Once you enter the formula in cell L3, you can copy it down to cells L4, L5, and L6. The formula will adjust automatically, retrieving the airport fee based on the discounted fare for each row.

a. The probability that the 10th transistor will be defective in the standard type is approximately 0.184.

b. The probability that a batch of 100 transistors will not have a defect in the standard type is approximately 0.133.

c. On average, approximately 50 transistors are produced before the first defect in the standard type, with a standard deviation of approximately 49.899.

d. For the newer type with a defective rate of 5%, the probability that the 10th transistor will be defective is approximately 0.328. The probability of a batch of 100 transistors not having a defect is approximately 0.006. On average, approximately 20 transistors are produced before the first defect, with a standard deviation of approximately 19.519.

e. For the older type with a defective rate of 1%, the probability that the 10th transistor will be defective is approximately 0.092. The probability of a batch of 100 transistors not having a defect is approximately 0.366. On average, approximately 100 transistors are produced before the first defect, with a standard deviation of approximately 99.498.

a. To find the probability that the 10th transistor will be defective in the standard type, we use the geometric distribution. The probability of a success (defect) is 0.02, and since we want to find P(X = 9), we calculate (1 - 0.02)^(9-1) * 0.02, which is approximately 0.184.

b. The probability that a batch of 100 transistors will not have a defect in the standard type is equal to (1 - 0.02)^100, which is approximately 0.133.

c. The expected value (average) of a geometric random variable is given by E(X) = 1/p, where p is the probability of success. In this case, E(X) = 1/0.02 = 50. The standard deviation of a geometric random variable is calculated as SD(X) = sqrt((1 - p) / p^2), which in this case is approximately 49.899.

d. For the newer type with a defective rate of 5%, we repeat the calculations from parts a-c using p = 0.05. The probability that the 10th transistor will be defective is (1 - 0.05)^(10-1) * 0.05, approximately 0.328. The probability of a batch of 100 transistors not having a defect is (1 - 0.05)^100, approximately 0.006. The expected value is E(X) = 1/0.05 = 20, and the standard deviation is SD(X) = sqrt((1 - 0.05) / 0.05^2) ≈ 19.519.

e. For the older type with a defective rate of 1%, we repeat the calculations from parts a-c using p = 0.01. The probability that the 10th transistor will be defective is (1 - 0.01)^(10-1) * 0.01, approximately 0.092. The probability of a batch of 100 transistors not having a defect is (1 - 0.01)^100, approximately 0.366. The expected value is E(X) = 1/0.01 = 100, and the standard deviation is SD(X) = sqrt((1 - 0.01) / 0.01^2) ≈ 99.498.

Answers

to create a program that meets the given requirements for printing a string with individual bit representations, follow the outlined steps, initialize registers, set up loops for lines and characters, print each bit, include line feed characters, and end with a HALT instruction.

To create a program that meets the given requirements, you will need to follow the steps outlined below:

1. Initialize the necessary registers:
  - Make sure to properly initialize all the registers that you will use in your program. Avoid using R7 for this purpose.
  - You may not assume anything about the initial contents of any register, so it's important to initialize them before proceeding with the program.

2. Set up a loop for each line in the output:
  - Use an iterative construct, such as a loop, to iterate through each line in the output.
  - This loop will ensure that you print all the characters, even if they are not visible on the monitor (e.g., spaces).

3. Set up a loop for each character in the string to be printed:
  - Use another iterative construct, such as a loop, to iterate through each character in the string to be printed.
  - Remember that a string ends with a NULL (x00) character, which should not be printed to the screen.
  - This loop will ensure that you print each character in the string.

4. Set up a loop for each bit to be printed for a given character:
  - Inside the loop for each character, use another iterative construct, such as a loop, to iterate through each bit to be printed for that character.
  - Determine whether the bit is a 0 or a 1 and print the corresponding character located at memory addresses x5000 or x5001 respectively.
  - This loop will ensure that you print each bit for the given character in the string.

5. Print a line feed character (x0A) at the end of each line:
  - After printing all the characters and bits for a given line, print a line feed character (x0A) to end the line.
  - This will ensure that each line is properly separated in the output.

6. Ensure that the last instruction executed is a HALT (TRAP x25):
  - In your program, make sure that the last instruction executed is a HALT (TRAP x25) instruction.
  - This will stop the program execution after all the characters and lines have been printed.

Remember to adhere to the given requirements, such as starting the code at memory location x3000 and using the specified memory addresses for the font data and the string to be printed.

ER ASSISTANT DIAGRAMS PLEASE (ONE DIAGRAM FOR ALL)
Draw an ERD for a lender’s database to track loans submitted by students to the lender. A student makes a loan application to the lender to pay for costs at a higher education institution. The database should track basic student details including a unique student identifier, student name, student address (street, city, state, and zip), date of birth, expected graduation month and year, and unique email address. For loan applications, the database should track the unique loan number, date submitted, date authorized, month and year of first academic term for the loan, loan amount, rate, status (pending, approved, or denied), guarantor number, and higher education institution.
Revise the ERD from problem 1 with more details about guarantor. A guarantor includes a unique guarantor identifier, name, and level (either full or partial). A guarantor guarantees many loan applications with each loan application having at most one guarantor. Loan applications in a pending or denied status do not have a guarantor assigned.
Revise the ERD from problem 2 with disbursements from approved loans to pay for a student’s tuition and fees. For an approved loan, a student receives one disbursement check per academic term for a portion of the loan amount related to tuition and fees in the academic term. Each disbursement of a loan includes the relative line number (unique within the related loan number), date sent, amount, origination fee, and guarantee fee. The loan number and relative line number of the disbursement identify a disbursement. Each disbursement relates to exactly one approved loan. An approved loan has one or more disbursements with line numbers consecutive for each disbursement.
Revise the ERD from problem 3 to include consolidated statements. A consolidated statement contains the amount due for each outstanding loan associated with a student. A statement includes a unique statement number, amount due, statement date, and due date. Since loan repayment does not begin until graduation or separation from school, the student on a loan application is a former student when the first statement is sent. A statement line includes a line number (unique within a statement), associated loan, principal amount due, and interest due. For a statement line, the combination of statement number and line number is unique. Each statement contains at least one statement line.
Revise the ERD from problem 4 so that each disbursement has a unique identifier for the electronic funds transfer. Although the combination of loan number and line number is still unique, the preferred way to identify a disbursement is the unique number for the electronic funds transfer.

Answers

A program can be written that converts heights in centimeters to feet and inches. Feet and inches are whole numbers, and the conversion should consider rounding to the nearest integer. This means, for example, that 2.0, 2.1, 2.2, 2.3, and 2.4 should be rounded to 2, and 2.5, 2.6, 2.7, 2.8, and 2.9 should be rounded to 3.

The below given program will provide you with the solution:

height = int (input("Enter the height in centimeter(s) -- "))conv_fac = 0.0328084

feet = height * conv_facint_

feet = int(feet)

remainder = feet - int_feetinches = remainder *

12int_inches = round(inches)if int_inches == 12:

int_inches = 0  int_feet += 1print(height, "centimeter (s)=", int_feet, "foot/feet and", int_inches, "inche(s)")

You can see that we are converting height in centimeters to feet using the following formula:

height in feet = height in centimeters * 0.0328084.

We can then separate the whole feet from the decimal feet by using the integer division operator //. To get the remainder in decimal feet, we use the modulus operator %. We can then convert the decimal feet to inches by multiplying it with 12.

In conclusion, we can write a program to convert heights in centimeters to feet and inches. This program will prompt the user to enter the height in centimeters, converts it to feet and inches, and displays the corresponding height in feet and inches. We used the formula "height in feet = height in centimeters * 0.0328084" to convert the height in centimeters to feet.

In this lab, the following topic will be covered: 1. Inheritance Task Create a class called Question that contains one private field for the question's text. Provide a single argument constructor. Override the toString() method to return the text. Create a subclass of Question called MCQuestion that contains additional fields for choices. Provide a constructor that has all the fields. Override the toString() method to return all data fields (use the toString() method of the Question class). Write a test program that creates a MCQuestion object with values of your choice. Print the object using the toString method.

Answers

In this lab, the main topic covered is inheritance. The lab instructs the creation of two classes, "Question" and "MCQuestion," which demonstrate the concept of inheritance. The "Question" class has a private field for the question's text and a constructor and toString() method. The "MCQuestion" subclass extends the "Question" class and adds additional fields for choices. It has a constructor that initializes all the fields and overrides the toString() method to display all data fields, including the inherited field from the "Question" class. A test program is written to create an instance of the "MCQuestion" class with chosen values and print the object using the toString() method.

In this lab, the concept of inheritance is introduced, which allows the creation of subclasses that inherit properties and behaviors from a superclass. The "Question" class serves as the superclass, providing the foundation for the "MCQuestion" subclass. By extending the "Question" class, the "MCQuestion" class inherits the private field for the question's text and the toString() method. The "MCQuestion" class then adds additional fields for choices and overrides the toString() method to display all data fields, including the inherited text field.

The test program demonstrates the usage of the "MCQuestion" class by creating an object with chosen values and printing it using the toString() method. This allows us to see the complete representation of the "MCQuestion" object, including the question text and the choices.

By following the instructions and implementing the classes and methods as described, we can understand and practice the concept of inheritance in object-oriented programming.

P2. (12 pts.) Suppose users share a 4.5Mbps link. Also suppose each user requires 250kbps when transmitting, but each user transmits only 15 percent of the time. (See the discussion of packet switching versus circuit switching.) a. When circuit switching is used, how many users can be supported? (2pts) b. For the remainder of this problem, suppose packet switching is used. Find the probability that a given user is transmitting. (2pts) c. Suppose there are 200 users. Find the probability that at any given time, exactly n users are transmitting simultaneously. (Hint: Use the binomial distribution.) (4pts) d. Find the probability that there are 25 or more users transmitting simultaneously. (4pts)

Answers

When circuit switching is used, 18 users can be supported. The probability that a given user is transmitting is  0.15. The probability that at any given time, exactly n users are transmitting simultaneously is (200 choose n)(0.15)^n(0.85)^(200-n). The probability that there are 25 or more users transmitting simultaneously is  1 - [P(0) + P(1) + ... + P(24)].

a.

In the case of circuit switching, a 4.5 Mbps link will be divided equally among users. Since each user needs 250 kbps when transmitting, 4.5 Mbps can support 4.5 Mbps / 250 kbps = 18 users.

However, each user transmits only 15 percent of the time. Thus, in circuit switching, 18 users can be supported if each user transmits 15 percent of the time.

b.

The probability that a given user is transmitting in packet switching can be found using the offered information that each user is transmitting 15% of the time.

The probability that a given user is transmitting is equal to the ratio of time that the user is transmitting to the total time. Thus, the probability that a given user is transmitting is 0.15.

c.

The probability of exactly n users transmitting simultaneously out of 200 users can be determined using the binomial distribution formula. For n users to transmit, n out of 200 users must choose to transmit and 200 - n out of 200 users must choose not to transmit.

The probability of exactly n users transmitting is then: P(n) = (200 choose n)(0.15)^n(0.85)^(200-n).

d.

To find the probability that 25 or more users are transmitting simultaneously, we can use the complement rule. The complement of the probability that 24 or fewer users are transmitting is the probability that 25 or more users are transmitting.

Thus, the probability that 25 or more users are transmitting is 1 - the probability that 24 or fewer users are transmitting. The probability of 24 or fewer users transmitting can be calculated as the sum of the probabilities of each of the cases from 0 to 24.

Thus, the probability of 24 or fewer users transmitting is: P(0)+P(1)+...+P(24), where P(n) is the probability of n users transmitting calculated in part c.

There are N holes arranged in a row in the top of an old table. We want to fix the table by covering the holes with two boards. For technical reasons, the boards need to be of the same length. The position of the K-th hole is A[K]. What is the shortest length of the boards required to cover all the holes? The length of the boards has to be a positive integer. A board of length L, set at position X, covers all the holes located between positions X and X+L (inclusive). The position of every hole is unique. Write a function: class Solution \{ public int solution(ini[] A); \} which, given an array A of integers of length N, representing the positions of the holes in the table, returns the shortest board length required to cover all the holes. Examples: 1. Given A=[11,20,15], your function should return 4. The first board would cover the holes in positions 11 and 15 , and the second board the hole at position 20. 2. Given A=[15,20,9,11], your function should return 5 . The first board covers the holes at positions 9 and 11, and the second one the holes in positions 15 and 20.

Answers

To find the shortest length of boards required to cover all the holes, we can observe that the boards need to span the minimum and maximum positions of the holes.

First, we sort the array A in ascending order. Then, we calculate the difference between the maximum and minimum positions, which gives us the initial shortest length.

Next, we iterate through the array A and check if there is a hole whose position lies between the current minimum and minimum + shortest length.

If we find such a hole, we update the minimum position to that hole's position and recalculate the shortest length using the new minimum and maximum positions.

After iterating through all the holes, we return the final shortest length.

Here is the implementation in Java:

```java

import java.util.Arrays;

class Solution {

   public int solution(int[] A) {

       Arrays.sort(A);

       int N = A.length;

       int shortestLength = A[N - 1] - A[0];

       for (int i = 0; i < N - 1; i++) {

           if (A[i] >= A[0] && A[i] <= A[0] + shortestLength)

               shortestLength = Math.max(A[i + 1] - A[0], shortestLength);

           else

               shortestLength = Math.max(A[i + 1] - A[i], shortestLength);

       }

       return shortestLength;

   }

}

```The time complexity of this solution is O(N log N) due to the sorting step, where N is the length of the array A.

The execution time and wasted issue slots for the given CPU organizations and threads vary based on their characteristics.

How does the performance of CPU organizations differ for the given threads?

The execution time and wasted issue slots for the provided threads (X and Y) depend on the specific CPU organization employed. In the single-core superscalar (SS) CPU, the execution time is 12 cycles with 4 wasted issue slots due to hazards.

However, using two SS CPUs reduces the execution time to 8 cycles with no wasted issue slots. On the other hand, a fine-grained multithreaded (MT) CPU and a simultaneous multithreading (SMT) CPU both exhibit execution times of 7 cycles with no wasted issue slots, thanks to concurrent thread execution.

This includes factors such as market trends, competitor analysis, and changes in regulations or technology. By understanding the external factors that may impact the organization, decision-makers can anticipate potential challenges and identify opportunities.

2. Internal Analysis: The next step is to assess the organization's internal strengths and weaknesses. This includes evaluating the organization's resources, capabilities, and core competencies. Understanding the organization's internal capabilities helps in identifying areas of competitive advantage and areas that need improvement.

3. Goal Setting: Based on the analysis of the external and internal environment, the organization can then set goals for the next two years. These goals should be specific, measurable, achievable, relevant, and time-bound (SMART goals). For example, the organization may set a goal to increase market share by a certain percentage or to launch a new product line.

4. Strategy Formulation: Once the goals are set, the organization needs to develop strategies to achieve those goals. Strategies are the action plans that outline how the organization will allocate resources and compete in the marketplace. This may involve decisions on pricing, product development, marketing, and partnerships.

5. Implementation and Monitoring: After formulating the strategies, it is crucial to implement them effectively. This involves allocating resources, assigning responsibilities, and creating a timeline. Regular monitoring and evaluation of progress are essential to ensure that the organization stays on track and makes necessary adjustments if needed.

By utilizing a strategic planning system, organizations can make informed decisions about the direction to take in the next two years. This system helps align the organization's resources and efforts toward achieving its goals and staying competitive in a dynamic business environment.

The data in a distribution can be anything. It could be in the form of raw or original measurements or some sort of data that is derived from raw data.

In other words, the data can be transformed in different ways to make it more meaningful and useful to the user. The important thing is that the distribution should be properly labeled and organized so that it can be easily interpreted and analyzed.
Measures of central tendency are statistics that describe the central location of a dataset. They help us understand where the data is centered and how it is spread out. They are used to represent the entire dataset in a single value. The measures of central tendency can be divided into three categories: Mean, Median, and Mode.
The mode is the value that appears most frequently in a dataset. It is used when the data is categorical, which means it cannot be measured on a numerical scale. The median is the middle value in a dataset. It is used when the data is ordered or ranked. The mean is the arithmetic average of the dataset. It is used when the data is numerical and continuous.
In conclusion, data in a distribution can be anything and the measures of central tendency that can be used with categorical data are mode.

In this question, we have to explain the values of the learning rate (Ir) and epoch number used to initialize Gradient Descent.

The learning rate, Ir, is a hyperparameter that decides the size of the steps that the algorithm takes in the direction of the optimal solution. If Ir is set too low, the algorithm will take too long to converge, while if Ir is set too high, the algorithm will overshoot the optimal solution and fail to converge.

The epoch number, on the other hand, is the number of iterations that Gradient Descent performs on the entire dataset. The epoch number should be set such that the algorithm is given enough time to converge to the optimal solution. However, setting epoch too high can cause overfitting.

Write a Java program that takes 10 integers from the user, calculate their sum and average, and print them. 4. Rewrite Question 3 but this time the user will enter an unknown number of integers. a) The user will enter 0 to specify that there are no more numbers. b) The user will enter a character to specify that there are no more numbers.

Answers

To write a Java program that takes 10 integers from the user, calculate their sum and average, and print them. Here is the code snippet to solve this question:

import java.util.Scanner;

public class Main { public static void main(String[] args) { Scanner input = new Scanner(System.in);

int n = 10;

int sum = 0;

int value;

for (int i = 0; i < n; ++i) { System.out.print("Enter an integer: ");

value = input.nextInt();

sum += value; } double average = (double)sum / n;

System.out.println("Sum = " + sum);

System.out.println("Average = " + average); } }

3.where the user will enter an unknown number of integers, and the user will enter 0 to specify that there are no more numbers, here is the code snippet:import java.util.Scanner;public class Main { public static void main(String[] args) { Scanner input = new Scanner(System.in); int sum = 0; int value; int count = 0; System.out.println("Enter integers (0 to quit): "); while ((value = input.nextInt()) != 0) { sum += value; ++count; } if (count == 0) { System.out.println("No input"); } else { double average = (double)sum / count; System.out.println("Sum = " + sum); System.out.println("Average = " + average); } } }.

The code for the program that takes 10 integers from the user and calculate their sum and average, we initialize Scanner input = new Scanner(System.in) to take input from the user. Then we declared three integers named as n = 10, sum = 0, and value. We used the for loop to iterate through 10 integers. The user is asked to enter an integer, and the entered value is stored in the value variable. After taking input from the user, we added all the integers and stored them in the sum variable. Then we calculated the average by dividing the sum by 10, i.e., number of integers and stored the result in the average variable. At last, the sum and average are printed on the screen by using System.out.println() function.

For the second part of the question, where the user will enter an unknown number of integers, we initialized the sum and count to 0. We used a while loop to keep taking input from the user until the entered value is 0. We added each entered value to the sum variable and increased the count by 1. Then we calculated the average by dividing the sum by the count and stored the result in the average variable. At last, the sum and average are printed on the screen by using System.out.println() function. If no input is entered, the program will print "No input." in the output. The character option is not considered in this solution

We wrote two different Java programs to calculate the sum and average of a given set of numbers. The first program takes 10 integers, and the second program takes an unknown number of integers from the user. The first program uses a for loop to iterate through the given integers, whereas the second program uses a while loop to keep taking input from the user until 0 is entered. Both programs calculate the sum and average of the given integers and print them on the screen.

True O False Scores on a Math test were normally distributed with a mean of 67% and a standard deviation of 8. Use this information to determine the following:About what percent of tests were below 75%?About what percent of the test, scores were above 83%?A failing grade on the test was anything 2 or more standard deviations below the mean. What was the cutoff for a failing score? Approximately what percent of the students failed?About what percent of the students were below a 80%?What percent of the students scored at least a 63% and at most a 83%?What percent of the students scored at least a 60% and at most a 72%? Suppose there are two stocks and two possible states. The first state happens with 85% probability and second state happens with 15% probability. In outcome 1 , stock A has 1% return and stock B has 12% return. In outcome 2 , stock A has 80% return and stock B has - 10% return. What is the covariance of their returns? Please enter a number (not a percentage). Please convert all percentages to numbers before calculating, then type in the number. Now type in 4 decimal places.

Hammers have a unit selling price of $300, a unit contribution margin of $100 and a contribution margin per direct labor hour of $300. Screwdrivers have a unit selling price of $250, a unit contribution margin of $200 and a contribution margin per direct labor hour of $280. Which product should she devote the limited resource to? The screwdrivers, because the unit contribution margin is greater than the hammers. The hammers, because the contribution margin per unit of limited resource is greater than the screwdrivers. The hammers, because unit selling price is greater than the screwdrivers. The screwdrivers, because the unit variable cost is less than the hammers.
