Answer:

B

Explanation:

all url's begin with https://

Answer:

a) $3482.4 per Kbyte

b) $0.000149 per Kbyte

c) The laptop is 23369991 times cheaper than the mainframe computer

d) Today's computer is 23369991 times cheaper than IBM 370

Explanation:

a) The 370 Model 145 could hold up to 524,288 bytes of data

one Kb = 1024 bytes, therefore  524,288 bytes =  524288/1024 Kbytes= 512 Kbytes. It cost $1,783,000.00 to buy (or $37,330/month to rent).

Since 100% of the price is just the memory

Cost per 1 Kb = cost of computer / memory

Cost per 1 Kb =  $1,783,000 / 512 Kb = $3482.4 per Kbyte

b)   A notebook computer today holds 16 Gbytes of memory

one Kb = 1024 bytes, 1024 Kb = 1 Mbyte, 1024 Mbytes = 1 Gbyte.

Therefore 16 Gbytes =  (16 * 1024 * 1024) Kbytes = 16777216 Kbytes. It cost $2500 to buy

Since 100% of the price is just the memory

Cost per 1 Kb = cost of computer / memory

Cost per 1 Kb =  $2500 /16777216 Kb = $0.000149 per Kbyte

c) Cost per 1 Kb for mainframe/ Cost per 1 Kb for laptop = $3482.4 per Kbyte / $0.000149 per Kbyte = 23369991

The laptop is 23369991 times cheaper than the mainframe computer

d) Today's computer is 23369991 times cheaper than IBM 370

Explanation:

To begin, i will like to break this down to its simplest form to make this as simple as possible.

Let us begin !

Here statement can be translated as: ∃x (P(x) ∧ M(x))

we require the Negation: ¬∃x (P(x) ∧ M(x))

De morgan's law can be stated as:

1) ¬(a ∧ b) = (¬a ∨ ¬b)

2) ¬(a v b) = (¬a ∧ ¬b)

Also, quantifiers are swapped.

Applying De Morgan's law, we have: ∀x (¬P(x) ∨ ¬M(x)) (∃ i swapped with ∀ and intersecion is replaced with union.)

This is the translation of above

Answer:

From the given address:  7d2b:00a9:a0c4:0000:a772:00fd:a523:0358

We can see that:

In general, Internet Protocol version 6 (IPv6) is the Internet Protocol (IP) which was developed to deal with the expected anticipation of IPv4 address exhaustion.

The IPv6 addresses are in the format of a 128-bit alphanumeric string which is divided into 8 groups of four hexadecimal digits. Each group represents 16 bits.

Since the size of an IPv6 address is 128 bits, the address space has [tex]2^{128}[/tex] addresses.

2 4 9

Explanation:

Basically what I thought was the way was, since 2 is first, then its 1, then since 4 is second, it's added second, lastly to get the last oneI added them all and got 9 so that's third.

Answer:

Does not exist.

Explanation:

The answer is not in the option:

Let's analyse the code:

random.randint(2,4)

This means take in random integer numbers starting with 2 and ending with 4.

Meaning numbers : 2, 3 and 4

Next math.pow(a,2) means a× a = a2

So when we input 2 the function;

math.pow(a,2) returns an integer 4

You do same for input 3 , it returns 9.

For input 4 it returns 16.

And the result is encapsulated in the function string(). Meaning display the result as a string:

4 9 16

Answer:

def scramble(s):

   if len(s) % 2 == 1:

       index = int(len(s)//2)

   else:

       index = int(len(s)/2)

   return s[index:] + s[:index]

Explanation:

Create a function called scramble that takes one parameter, s

Check the length of the s using len function. If the length is odd, set the index as the floor of the length/2. Otherwise, set the index as length/2. Use index value to slice the s as two halves

Return the second half of the s and the second half of the s using slice notation (s[index:] represents the characters from half of the s to the end, s[:index] represents the characters from begining to the half of the s)

Answer:

This program is written in Java programming language;

First, you should understand that:

The formula given in the question implies that the current temperature can only be calculated using measurement of time in minutes;

Given that the number of chirps is directly proportional to the temperature.

If the cricket made n chirps in 15 seconds, it will make n * (60/15) chirps in 1 minutes;

n * (60/15) = n * 4

Base on this analysis, the program is as follows

import java.util.*;

public class cricket

{

public static void main(String []args)

{

 //Declare number of chips in 1 minutes

 int num;

 Scanner input = new Scanner(System.in);

 //Prompt user for input

 System.out.print("Number of chirps (in 15 seconds): ");

 num = input.nextInt();

 //Calculate temperature  (multiply temperature by 4 to get number of chirps in minutes

 double temp = (num * 4+ 40)/4;

 //Print temperature

 System.out.print("Current Temperature = "+temp+" F");

}

}

a. starting balance

Explanation:

A program that calculates the current balance of a savings should ask the user for the starting balance and then ask for the annual interest rate. A loop should then iterate once for every month of the savings period in order to perform other tasks such as asking the user for the total amount deposited into the account, the total amount withdrawn from the account, and calculate the interest rate. The program will then proceed to display the result at the end of the savings period.

           int numOfStars = MAX_ROWS - (getNumberOfSpaces(row) * 2);

           String spaces = printSpaces(numOfSpaces);

           String stars = printStars(numOfStars);

           System.out.println(spaces + stars);

       }

    }

    public static int getNumberOfSpaces(int row) {

        int rowOffset = (MAX_ROWS / 2) + 1;

        return Math.abs(row-rowOffset);

    }

    public static String printSpaces(int num) {

        String result = "";

        for (int i = 0; i < num; i++) {

            result += " ";

        }

        return result;

    }

        String result = "";

        for (int i = 0; i < num; i++) {

            result += "*";

        }

        return result;

    }

}

Explanation:

So it sounds we need to make a diamond shape out of asterisks like this:

  *

 ***

*****

*******

*****

 ***

  *

There are 7 rows and each row has up to 7 characters. The pattern is also symmetrical which makes it easier. Before writing any code, let's figure out how we are going to determine the correct amount of spaces we need to print. There are a lot of ways to do this, but I'll just show one. Let's call the 4th row y=0. Above that we have row 3 which would be y=-1, and below is row 5 which is y=1. With 7 rows, we have y=-3 through y=3. The absolute value of the y value is how many spaces we need.

To determine the number of stars, we just double the number of spaces, then subtract this number from 7. This is because we can imagine that the same amount of spaces that are printed in front of the stars are also after the stars. We don't actually have to print the second set of spaces since it is just white space, but the maximum number of characters in a row is 7, and this formula will always make sure we have 7.

I hope this helps. If you need help understanding any part of the code, jsut let me know.

Answer:

B. Cross-train agents on both product lines

D. Implement a customer self-service portal

Explanation:

Cross-training is a way of teaching employees different aspects of the job so that they can have a measure of flexibility in the discharge of duties. Managers find this approach to be effective as they believe it saves cost and maximizes the usefulness of employees. It also helps to serve and satisfy a wider range of customers.

So for Universal Containers seeking to optimize cost without compromising customer satisfaction while managing two customer service contact centers, an effective way of dealing with the large call volumes is cross-training agents on both product lines so that they can attend to a wider range of customers. Cross-training agents on both product lines would make them more knowledgeable of the services being offered and this would minimize the need to transfer calls as all agents can provide information on the various products.

Implementing a customer self-service portal would also reduce the workload on the customer service agents as customers can access the information they need on their own.

Option B: Attack

Explanation:

A security attack is an act to access to a system without a legit authorization. Usually the aim is to steal confidential info from the system or control the system by manipulating the data stored in the system. Some attacks are also aimed to disable the operation of the hacked system. Nowadays, there are several common types of security attacks which include

Answer:

Here is the Python program.

characters = 0

words = 0

lines = 0

def file_stats(in_file):

   global lines, words, characters

   with open(in_file, 'r') as file:

       for line in file:

           lines = lines + 1

           totalwords = line.split()

           words = words + len(totalwords)

           for word in totalwords:

               characters= characters + len(word)

file_stats('created_equal.txt')

print("Number of lines: {0}".format(lines))

print("Number of words: {0}".format(words))

print("Number of chars: {0}".format(characters))

Explanation:

The program first initializes three variables to 0 which are: words, lines and characters.

The method file_stats() takes in_file as a parameter. in_file is the name of the existing text file.

In this method the keyword global is used to read and modify the variables words, lines and characters inside the function.

open() function is used to open the file. It has two parameters: file name and mode 'r' which represents the mode of the file to be opened. Here 'r' means the file is to be opened in read mode.

For loop is used which moves through each line in the text file and counts the number of lines by incrementing the line variable by 1, each time it reads the line.

split() function is used to split the each line string into a list. This split is stored in totalwords.

Next statement words = words + len(totalwords)  is used to find the number of words in the text file. When the lines are split in to a list then the length of each split is found by the len() function and added to the words variable in order to find the number of words in the text file.

Next, in order to find the number of characters, for loop is used. The loop moves through each word in the list totalwords and split each word in the totalwords list using split() method. This makes a list of each character in every word of the text file. This calculates the number of characters in each word. Each word split is added to the character and stored in character variable.

file_stats('created_equal.txt')  statement calls the file_stats() method and passes a file name of the text file created_equal.txt as an argument to this method. The last three print() statements display the number of lines, words and characters in the created_equal.txt text file.

The program along with its output is attached.

Answer:

The correct answer is option A

Explanation:

Solution

Recall that:

From the question stated,the following segments of code that should be used in replacing the /* missing code */ so that the value 20 will be printed is given below:

Android a = new Android(x);

a.setServoCount(y);

System.out.println(a.getServoCount());

The right option to be used here is A.

Based on the information given, the code segments that's appropriate will be A  Android a = new Android(x);

From the question stated, it was inferred that we should get the segments of code that should be used in replacing the /* missing code */ so that the value 20 will be printed.

This will be:

Android a = new Android(x);

a.setServoCount(y);

System.out.println(a.getServoCount());

In conclusion, the correct option is A.
