Create an application for a library and name it FineForOverdueBooks. TheMain() method asks the user to input the number of books
andrew11 [14]

Answer:

//The Scanner class is imported which allow the program to receive user input

import java.util.Scanner;

//Class Solution is defined to hold problem solution

public class Solution {

   // The main method which signify the begining of program execution

   public static void main(String args[]) {

       // Scanner object 'scan' is defined to receive input from user keyboard

       Scanner scan = new Scanner(System.in);

       // A prompt is display asking the user to enter number of books

       System.out.println("Please enter number of books: ");

       // the user response is assigned to numberOfBook

       int numberOfBook = scan.nextInt();

       // A prompt is displayed asking the user to enter the number of days over due

       System.out.println("Please enter number of days over due: ");

       // the user response is assigned to numberOfDaysOverDue

       int numberOfDaysOverDue = scan.nextInt();

       //displayFine method is called with numberOfBook and numberOfDaysOverDue as arguments

       displayFine(numberOfBook, numberOfDaysOverDue);

   

   }

   

   //displayFine method is declared having two parameters

   public static void displayFine(int bookNumber, int daysOverDue){

       // fine for first seven days is 10cent which is converted to $0.10

       double firstSevenDay = 0.10;

       // fine for more than seven days is 20cent which is converted to $0.20

       double moreThanSevenDay = 0.20;

       // the fine to be paid is declared

       double fine = 0;

       // fine is calculated in the following block

       if(daysOverDue <= 7){

           //the fine if the over due days is less than or equal 7

           fine = bookNumber * daysOverDue * firstSevenDay;

       } else{

           // the extra days on top of the first seven days is calculated and assigned to extraDays

           int extraDays = daysOverDue - 7;

           //fine for first seven days is calculated

           double fineFirstSevenDays = bookNumber * 7 * firstSevenDay;

           // fine for the extradays is calculated

           double fineMoreThanSevenDays = bookNumber * extraDays * moreThanSevenDay;

           // the total fine is calculated by adding fine for first seven days and the extra days

           fine = fineFirstSevenDays + fineMoreThanSevenDays;

       }

       // The total fine is displayed to the user in a nice format.

       System.out.printf("The fine for " + bookNumber + " book(s) for " + daysOverDue + " day(s) is: $%.02f", fine);

   }

}

Explanation:

The program first import Scanner class to allow the program receive user input. Then the class Solution was defined and the main method was declared. In the main method, user is asked for number of books and days over due which are assigned to numberOfBook and numberOfDaysOverDue. The two variable are passed as arguments to the displayFine method.

Next, the displayFine method was defined and the fine for the first seven days is calculated first if the due days is less than or equal seven. Else, the fine is calculated for the first seven days and then the extra days.

The fine is finally displayed to the user.

Which statement will call this module and pass 12 as the argument?
WITCHER [35]

Answer:

Call showValue (12)

Explanation:

The function is a block of the statement which performs the special task.

if you define the function, then you have to call that function.

Then, program control moves to the function and start to execute otherwise not execute the function.

the syntax for calling the function:

name(argument_1, argument_2,....);

we can put any number of arguments in the calling.

check the options one by one for finding the answer:

Call showValue( Integer): this is valid calling but it passes the variable, not the 12. this is not correct.

Call showValue( Integer 12): This is not valid calling, because it passes the data type as well which is incorrect.

Call showValue( Real): this is valid calling but it passes the variable, not the 12. this is not correct.

Call showValue (12): this valid calling and also pass the value 12.

Therefore, the correct answer is option b.

// This pseudocode segment is intended to compute and display
Finger [1]

The pseudocode to calculate the average of the test scores until the user enters a negative input serves as a prototype of the actual program

<h3>The errors in the pseudocode</h3>

The errors in the pseudocode include:

  • Inclusion of unusable segments
  • Incorrect variables
  • Incorrect loops

<h3>The correct pseudocode</h3>

The correct pseudocode where all errors are corrected and the unusable segments are removed is as follows:

start

Declarations

     num test1

     num test2

     num test3

     num average

output "Enter score for test 1 or a negative number to quit"

input test1

while test1 >= 0

     output "Enter score for test 2"

     input test2

     output "Enter score for test 3"

     input test3

     average = (test1 + test2 + test3) / 3

     output "Average is ", average

     output "Enter score for test 1 or a negative number to quit"

     input test1

endwhile

output "End of program"

stop

What would you have to know about the pivot columns in an augmented matrix in order to know that the linear system is consistent
Scrat [10]

Answer:

The Rouché-Capelli Theorem. This theorem establishes a connection between how a linear system behaves and the ranks of its coefficient matrix (A) and its counterpart the augmented matrix.

rank(A)=rank\left ( \left [ A|B \right ] \right )\:and\:n=rank(A)

Then satisfying this theorem the system is consistent and has one single solution.

Explanation:

1) To answer that, you should have to know The Rouché-Capelli Theorem. This theorem establishes a connection between how a linear system behaves and the ranks of its coefficient matrix (A) and its counterpart the augmented matrix.

rank(A)=rank\left ( \left [ A|B \right ] \right )\:and\:n=rank(A)

rank(A)

Then the system is consistent and has a unique solution.

<em>E.g.</em>

\left\{\begin{matrix}x-3y-2z=6 \\ 2x-4y-3z=8 \\ -3x+6y+8z=-5  \end{matrix}\right.

2) Writing it as Linear system

A=\begin{pmatrix}1 & -3 &-2 \\  2& -4 &-3 \\ -3 &6  &8 \end{pmatrix} B=\begin{pmatrix}6\\ 8\\ 5\end{pmatrix}

rank(A) =\left(\begin{matrix}7 & 0 & 0 \\0 & 7 & 0 \\0 & 0 & 7\end{matrix}\right)=3

3) The Rank (A) is 3 found through Gauss elimination

(A|B)=\begin{pmatrix}1 & -3 &-2  &6 \\  2& -4 &-3  &8 \\  -3&6  &8  &-5 \end{pmatrix}

rank(A|B)=\left(\begin{matrix}1 & -3 & -2 \\0 & 2 & 1 \\0 & 0 & \frac{7}{2}\end{matrix}\right)=3

4) The rank of (A|B) is also equal to 3, found through Gauss elimination:

So this linear system is consistent and has a unique solution.
