the implementation of the method adjustSign() is to always multiply both denominator and numerator by -1 to ensure that fraction will never have the negative sign represented in the denominator. Group of answer choices True False

Problem: To write the JUnit test cases for our methods, you need to create two test methods: testLeapYear: This method should test if the isLeapYear method returns true for a given leap year. For example, you can choose the year 2020 and verify if the method returns true for it. If it does, the test will pass. If it doesn't, the test will fail. testNotLeapYear: This method should test if the isLeapYear method returns false for a given non-leap year. For example, you can choose the year 1900 and verify if the method returns false for it. If it does, the test will pass. If it doesn't, the test will fail. ---------------------------------------------------------------------------------------------------------------------------------------------------------   import static org.junit.jupiter.api.Assertions.assertTrue; import org.junit.jupiter.api.Test; public class LeapYearTest {   // Test case to check if a year is a leap year   @Test   public void testLeapYear() {     //create…

Write a solution algorithm to find the mean ages of students in a class using a method pseudocode

Don't change variable names and please don't use the answer on another site.  thank you

using java language Your program will identify if the shape is a square or a rectangle. Input the length and width of the shape, and display if it’s a rectangle or square, with its area and perimeter. Use the following methods in your program. inputLength() – returns the input length; inputWidth() – returns the input width; analyze(length,width) – based on the parameters length and width, returns a Boolean value if the shape is square or not compute(length,width) – based on the parameters length and width, display the area and the perimeter of the shape.

2. A pentagonal number is defined as n(3n-1)/2 for n = 1, 2, ..., etc.. Therefore, the first few numbers are 1, 5, 12, 22, ... . Write a method with the following header that returns a pentagonal number: %3D public static int getPentagonalNumber(int n) For example, getPentagonalNumber(1) returns 1 and getPentagonalNumber(2) returns 5. Write a test program that uses this method to display the first 100 pentagonal numbers with 10 numbers on each line. Numbers are separated by exactly one space.

Python Only Write a method that prints the fibonnaci sequence containing only evenor odd numbers. Your method should expect two parameters. One thattells you how many numbers of the sequence you want to see and if thenumbers should be even or odd.Example of Even: 0, 2, 8, 34, 144, 610, 2584 ...Example of Odd: 1, 1, 3, 5, 13, 21, 55, 89 ...

Use the left to right addition method as outlined in the module to add the numbers. For the middle row of answers, if the number above needs an underline, type in an underline (_).

A pentagonal number is defined as n(3n-1)/2 for n = 1, 2, …, and so on. Therefore, the first few numbers are 1, 5, 12, 22, . . . . Write a method with the following header that returns a pentagonal number: publicstaticintgetPentagonalNumber(int n) For example, getPentagonalNumber(1) returns 1 and getPentagonal- Number(2) returns 5. Write a test program that uses this method to display the first 100 pentagonal numbers with 10 numbers on each line. Use the %7d format to display each number.

A pentagonal number is defined as n (3 n-1)/ 2 for n= 1, 2,.. so on. Therefore, the first few numbers are 1, 5, 12, 22, .. Write a method with the following header that returns a pentagonal number: pue
