- True or FalseA value-returning method must contain a return statement.Financial Application:• Write a program that computes future investment value at a given interest rate for aspecified number of months and prints the report shown in the sample output. • Given the annual interest rate, the interest amount earned each month is computedusing the formula: Interest earned = investment amount * annual interest rate /1200 (=months * 100) • Write a method, computeFutureValue, which receives the investment amount, annualinterest rate and number of months as parameters and does the following: o Prints the interest amount earned each month and the new value of theinvestment (hint: use a loop). o Returns the total interest amount earned after the number of months specified bythe user. The main method will:o Ask the user for all input needed to call the computeFutureValue method.o Call computeFutureValueo Print the total interest amount earned by the investment at the end of thenumber of months entered by the user. Sample Program runningEnter the investment…TRUE-FALSE: Type YES if the given statement is correct. Otherwise, type NO. Analyzing information nowadays is easier than in the past.
- C# n Chapter 6, you continued to modify the GreenvilleRevenue program. Now, modify the program so that the major functions appear in the following individual methods: GetContestantNumber - This method gets and returns a valid number of contestants and is called twice once for last year’s number of contestants and once for this year’s value DisplayRelationship - This method accepts the number of contestants this year and last year and displays one of the three messages that describes the relationship between the two contestant values GetContestantData - This method fills the array of competitors and their talent codes GetLists - This method continuously prompts for talent codes and displays contestants with the corresponding talent until a sentinel value is entered An example of the program is shown below: Enter number of contestants last year >> 2 Enter number of contestants this year >> 3 Last year's competition had 2 contestants, and this year's has 3 contestants…Credit Card Number CheckThe last digit of a credit card number is the check digitwhich protects against transcription errors such as an error in a single digit or switching two digits. The following method is used to verify actual credit card numbers but, for simplicity, we will describe it for numbers with 8 digits instead of 16: Starting from the rightmost digit, form the sum of every other digit. For example, if the credit card number is 4358 9795, then you form the sum 5 + 7 + 8 + 3 = 23 . Double each of the digits that were not included in the preceding step. Add all digits of the resulting numbers . For example, with the number given above, doubling the digits. starting with the next-to-last one, yields 18 18 10 8. Adding all digits in these values yields 1 + 8 + 1 + 8 + 1 + 0 + 8 = 27 Add the sums of the two preceding steps . If the last digit of the result is 0, the number is valid . In our case , 23 + 27 = 50 , so the number is valid . Write a program that implements this…Assignment: Convert feet into meters: Write a program which reads the number in feet, converts it to meters, and displays the result. One foot is 0.305 meters.

- java finding Distance Between Points Write method distance used to calculate the distance between two points (x1, y1) and (x2, y2). numbers,return values should be type double. Incorporate this method into an application that enables the user to enter the coordinates of the points.Python question Application: Python Fragment Formulation (Q1 – Q4) In this group of questions you are asked to produce short pieces of Python code. When you are asked to "write a Python expression" to complete a task, you can either give the expression in one line or break down the task into several lines. The last expression you write must represent the required task. Question 1 (Reduce parentheses) Give an equivalent version of this expression by removing as many redundant parentheses as possible, without expanding the brackets or simplifying. (x**(2**y))+(y*((z+x)**3)) Question 2 (Translate arithmetic concept into Python) You are given a list of numbers, named numbers, containing 3 integers. Write a python expression (one line) that evaluates to True if and only if the product of any two numbers in the given list is greater than the sum of all three numbers. Note: the product of two numbers, x and y is x*y. Question 3 (List/table access) You are given a table,…Problem Description: In the Whimsical Library, each book is enchanted with a magical code to ensure the protection of knowledge. The validation process for these magical codes involves a combination of mathematical spells. The validation process is described as follows: Take the sum of the digits at odd positions from left to right. Take the sum of the squared digits at even positions from left to right. If the absolute difference between the results from step 1 and step 2 is a prime number, the book code is considered valid; otherwise, it is invalid. Example 1: Consider the magical book code 86420137. Step 1. Take the sum of the digits at odd positions from left to right. 8+4+0+3=15 Step 2. Take the sum of the squared digits at even positions from left to right. 6^2+2^2+1^2+7^2=36+4+1+49 = 90 Step 3. If the absolute difference between the results from step 1 and step 2 is a prime number. 115-901 75 (not a prime number) Book code 86420137 is invalid. Example 2: Now, let's examine the…
