Identify a data type applied in an input element to create slider controls.

Charlie has a large book collection. He was keeping track of it in a spreadsheet, but it has grown big enough that he wants to c

zepelin [54]

Answer:

Check the explanation

Explanation:

Ans 1) storing the data in one single row comes with its own barriers and that is if you delete one of the record in the spreadsheet, all the equivalent records which you didn't wanted to delete would be deleted. For take for instance, if you wish to delete the record of author "James Taylor" then all the books he has written would also be deleted from the spreadsheet.

Ans 2) In 1NF, all row is expected to have only 1 tuple, but here in this spreadsheet the title field for Author "James Taylor" has 2 books, so it would be separated into single rows.

Ans 3) The table in the attached image below doesn't delete with Delete anomaly, i.e., for author "May Norton" if you delete this record, then the only book written by her would be deleted.

So, you have to convert this table into 2NF.

Make separate tables for Author and Book

Author(Author Name, Author Country)

Books(Author Name, Book title, Publisher, Publisher Location, Year, price)

This cannot be normalized any further.

A bunch of computer scientists take over an island and start their own country. They want the license plates to use binary numbe

Thepotemich [5.8K]

Answer:

Their country can support 128 unique license plates

Explanation:

Since there is space for 7 digits on each license plate, the first plate starts at 0000000 (seven 0).

Binary numbers contain only the digits 0 and 1.

Thus, there are only two possibilities for each digit.

Using the multiplication counting principle, the number of total different binary numbers, with seven digits is 2 multiplied seven times:

2 × 2 × 2 × 2 × 2 × 2 × 2 = 2⁷ = 128 ← answer

Get user input as a boolean and store it in the variable tallEnough. Also, get user input as a boolean and store it in the varia

frozen [14]

Answer:

I will code in JAVA.

import java.util.Scanner;

public class Main {

public static void main(String[] args) {

boolean tallEnough;

boolean oldEnough;

Scanner input = new Scanner(System.in);

tallEnough = input.nextBoolean(); //wait the input for tallEnough

oldEnough = input.nextBoolean(); //wait the input for OldEnough

if(tallEnough && oldEnough){

System.out.print(true);

} else {

System.out.print(false);

}

Explanation:

First, to accept user inputs you have to import the class Scanner. Then declare both variables before allowing the user to set input values for both boolean variables.

In the if-else statement checks if both variables are true, then prints true. Another case prints always false.
