Answer:
- import java.util.Scanner;
-
- public class Main {
- public static void main(String[] args) {
- Scanner input = new Scanner(System.in);
- System.out.print("Input total sales of month: ");
- double totalSales = input.nextDouble();
-
- double stateTax = totalSales * 0.04;
- double countyTax = totalSales * 0.02;
- double totalSalesTax = stateTax + countyTax;
-
- System.out.println("County Tax: $" + countyTax);
- System.out.println("State Tax: $" + stateTax);
- System.out.println("Total Sales Tax: $" + totalSalesTax);
- }
- }
Explanation:
Firstly, create a Scanner object and prompt user to input total sales of month (Line 5-7). Next, apply the appropriate tax rate to calculate the state tax, county tax (Line 9 - 10). Total up the state tax and county tax to get the total sales tax (Line 11).
At last, print the county tax, state tax and the total sales tax (Line 13 - 15).
Programs are series of instructions interpreted by a computer
- The description of the program is to compute the square of the difference between corresponding elements of two arrays
- The better version of the program is program A.
<h3>How to describe the programs</h3>
From the programs, we have the following highlights
- The program iterates from 1 to n - 1
- The iteration calculates the difference between corresponding elements of the arrays
- The difference is then squared
Hence, the description of the program is to compute the square of the difference between corresponding elements of two arrays
<h3>The better version</h3>
The better version of the program is program A.
This is so, because the program uses fewer instructions for the same task as program B

Answer:
Explanation:
The underlined traits in the ER chart speak to essential key since they remarkably recognize the quality
(a)
(I) The level of the given relationship is 2 i.e it is a parallel connection among Book and Publisher. It is a one to numerous relationship from distributer to book in light of the fact that a distributer can distribute any number of books however a book will have only one publisher,so the cardinality will be 1 to 1..* (one to many)
(b)
(i) The degree of the given relationship is 2 i.e it is a binary relationship between Author and Book. It is a many to many relationship from Book to Author a book can be written by one or more authors and an author can write more than one book, so the cardinality will be 1..* to 1..* (many to many)
(c)
(i) As mentioned in part (b), the degree of given relation is 2 and cardinality is many to many (1..* to 1..*)
(d)
(i) The degree of the given relationship is 1 i.e unary relationship. It is a many to many relationship because one book can belong to any sets and a set can have any number of books, so cardinality is 1..* to 1..* (many to many)
