Hi ! How can you return the value of the class computeDiscountInfo to the variable savings in the main class ?
Here is my code :
import java.util.Scanner;
public class RoomCost{
public static void main (String [] args){
double price;
double discount;
double savings;
Scanner keyboard = new Scanner(System.in);
System.out.print("Enter cutoff price for discount $>> ");
price = keyboard.nextDouble();
System.out.print("Enter discount rate as a whole number >> ");
discount = keyboard.nextDouble();
displayinfo();
//insert code to set the value returned from computeDiscountInfo method to savings);
// savings =
System.out.println("Special this week on any room over " + price);
System.out.println("Discount of " + discount + " percent");
System.out.println("That's a savings of at least $" + savings);
}
public static void displayinfo(){
System.out.println("We want your stay to be memorable.");
System.out.println("We promise to make you as comfortable as possible.");
}
public static double computeDiscountInfo(double price, double discountRate)
{
double savings;
//(insert code to calculate savings as price multiplied by discount divided by 100);
savings = (price * discountRate)/100;
return savings;
}
}
Answers
Answer:
savings = computeDiscountInfo(price, discount);
Explanation:
First of all computeDiscountInfo is a function, not a class.
You can call this function and assign its return value to a variable, savings in this example.

Write a function named square_list that takes as a parameter a list of numbers and replaces each value with the square of that value. It should not return anything - it should mutate the original list.
Answers
Answer:
The function is as follows:
def square_list(myList):
for i in range(len(myList)):
myList[i] = myList[i]**2
print(myList)
Explanation:
This defines the function
def square_list(myList):
This iterates through the list elements
for i in range(len(myList)):
This squares each list element
myList[i] = myList[i]**2
This prints the mutated list
print(myList)

Assume a TCP sender is continuously sending 1,090-byte segments. If a TCP receiver advertises a window size of 5,718 bytes, and with a link transmission rate 26 Mbps an end-to-end propagation delay of 22.1 ms, what is the utilization
Answers
Answer:
for the 5 segments, the utilization is 3.8%
Explanation:
Given the data in the question;
segment size = 1090 bytes
Receiver window size = 5,718 bytes
Link transmission rate or Bandwidth = 26 Mbps = 26 × 10⁶ bps
propagation delay = 22.1 ms
so,
Round trip time = 2 × propagation delay = 2 × 22.1 ms = 44.2 ms
we determine the total segments;
Total segments = Receiver window size / sender segment or segment size
we substitute
Total segments = 5718 bytes / 1090 bytes
Total segments = 5.24587 ≈ 5
Next is the throughput
Throughput = Segment / Round trip
Throughput = 1090 bytes / 44.2 ms
1byte = 8 bits and 1ms = 10⁻³ s
Throughput = ( 1090 × 8 )bits / ( 44.2 × 10⁻³ )s
Throughput = 8720 bits / ( 44.2 × 10⁻³ s )
Throughput = 197.285 × 10³ bps
Now Utilization will be;
Utilization = Throughput / Bandwidth
we substitute
Utilization = ( 197.285 × 10³ bps ) / ( 26 × 10⁶ bps )
Utilization = 0.0076
Utilization is percentage will be ( 0.0076 × 100)% = 0.76%
∴ Over all utilization for the 5 segments will be;
⇒ 5 × 0.76% = 3.8%
Therefore, for the 5 segments, the utilization is 3.8%

Sites like Zillow get input about house prices from a database and provide nice summaries for readers. Write a program with two inputs, current price and last month's price (both integers). Then, output a summary listing the price, the change since last month, and the estimated monthly mortgage computed as (current_price * 0.051) / 12. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: print('{:.2f}'.format(your_value))
Answers
Answer:
The program in Python is as follows:
current_price = int(input("Current Price: "))
last_price = int(input("Last Month Price: "))
change = current_price - last_price
mortgage = (current_price * 0.051) / 12
print('Change: {:.2f} '.format(change))
print('Mortgage: {:.2f}'.format(mortgage))
Explanation:
This gets input for current price
current_price = int(input("Current Price: "))
This gets input for last month price
last_price = int(input("Last Month Price: "))
This calculates the price change
change = current_price - last_price
This calculates the mortgage
mortgage = (current_price * 0.051) / 12
This prints the calculated change
print('Change: {:.2f} '.format(change))
This prints the calculated monthly mortgage
print('Mortgage: {:.2f}'.format(mortgage))
Answer:
current_price = int(input())
last_months_price = int(input())
change = current_price - last_months_price
mortgage = current_price * 0.051 / 12
print('This house is $', end= '')
print(current_price, end= '. ')
print('The change is $', end= '')
print(change, end= ' ')
print('since last month.')
print('The estimated monthly mortgage is $', end= '')
print(mortgage, end='0.\n')
Chassis intrusion detection is an option that can be enabled/disabled in the BIOS setup utility (if a BIOS comes equipped with this feature).Coupled with a hardware sensor mounted insided the computer case, this functionality can be used to check if the case was opened and display a notification alert during next boot.
a. True
b. False
Answers
Answer: True
Explanation:
Chassis intrusion detection is simply a vital security feature which is used typically by large corporate networks. It's simply an intrusion detection method which can be used in alerting a system administrator when there's a situation whereby a person opens a computer case which can then be investigated in order to know if the computer hardware has been tampered with.
It should also be noted that the chassis intrusion detection can then be either enabled or disabled in the BIOS setup utility if a BIOS comes equipped with this feature.
The correct option is True.
Write the code for the following problem.
Add a function to problem to display the last name and highest, last name and lowest and average exam score. Hint: for highest initialize a variable to 0 (high_var). If the array value is higher than the high_var then set high_var to the array value and set high_index to the position of the array. Proceed through the array until you get to the end. Do the same for finding the lowest using low_var set to 999 (higher than the highest value). For the average score, sum all the exam scores as you proceed through the loop. Use a for loop to go through each occurrence of the arrays. Note you can do all this with one for loop but if it makes more sense to you to use multiple for loops that is ok too.

Answers
Answer:
A good identifier for a variable that will be used to hold an employee’s phone number is:
a. EmployeePhoneNumber
Explanation:
An identifier is a string that uniquely identifies or names the entity or an object. The object or entity may be a constant, variable, structure, function, etc. Identifiers can be formed from uppercase and lowercase letters, digits, and underscores. Meaningful identifiers mostly favor the use of long descriptive names like EmployeePhoneNumber. However, the other options can still be used.
A hammer tool can only be used by one technician at a time to perform hitting. Accordingly, you have developed a Hammer class with a hit method. Objects of class Hammer are used to simulate different hammers, while threads are created to simulate users. Which situation needs to add the synchronized keyword to the hit method
Answers
Answer:
Explanation:
The synchronized keyword needs to be active on the hit method at any point where 2 or more threads (users) exists at any given moment. This is in order to prevent two or more users from trying to perform a hammer hit at the same time. This is what the synchronized keyword is used for. It prevents the more than one thread from calling the specific method at the same time. Instead it adds the action to a sequence so that the second thread calls the hit method only after the first thread's hit method finishes.
