Programming Language : R programming (R Studio) A twin prime is a prime that has a prime gap of two. Sometimes the term twin prime is used for a pair of twin primes. For example, the five twin prime pairs are (3, 5), (5, 7), (11, 13), (17, 19) and (29, 31). Write a function that returns the number of all twin prime pairs between 1 and a given number n.

A twin prime is a prime that has a prime gap of two. Sometimes the term twin prime is
used for a pair of twin primes. For example, the five twin prime pairs are (3, 5), (5, 7),
(11, 13), (17, 19) and (29, 31). Write a function that returns the number of all twin prime
pairs between 1 and a given number n.

- (Data processing) Your professor has asked you to write a C++ program that determines grades at the end of the semester. For each student, identified by an integer number between 1 and 60, four exam grades must be kept, and two final grade averages must be computed. The first grade average is simply the average of all four grades. The second grade average is computed by weighting the four grades as follows: The first grade gets a weight of 0.2, the second grade gets a weight of 0.3, the third grade gets a weight of 0.3, and the fourth grade gets a weight of 0.2. That is, the final grade is computed as follows: 0.2grade1+0.3grade2+0.3grade3+0.2grade4 Using this information, construct a 60-by-7 two-dimensional array, in which the first column is used for the student number, the next four columns for the grades, and the last two columns for the computed final grades. The program’s output should be a display of the data in the completed array. For testing purposes, the professor has provided the following data:REVERSED SUM OF ODD POSITIONS Write a function that takes an integer(n) as input and returns True if the sum of its digits at odd positions is even, and returns False of otherwise. Positions are counted from the least significant digit. stion For example: n = 2345 →> True Explanation: The digits at odd positions are 5 and 3, and their sum i.e. 8 is even. Examples: rev_sum of odd_pos(2345) - True - False rev_sum_of_odd_pos(5728) *Note: Please return your output. Don't print your answer inside the function.

For example, 18 is a harshad number because 1 + 8 = 9 and 18 is divisible by 9. Write a function that returns the number of harshad numbers between 1 and 1000000.
- C program to find the nth prime number using a helper function called findPrime(int n), which returns true for prime number and false for non-prime number. The prime number series is: 2, 3, 5, 7, 9. 2 is the 1st prime number, 3 is the 2nd prime number. This program should find the nth number in this series.function [P, A] = rect(L, W) P= 2 (L+ W); A =L*W; end Above function is defined to find perimeter and area of a rectangle. If a rectangle has length 10 mm and width 7 mm then the correct way to get perimeter and area of a given rectangle by executing this function is Select one: a. [A, B] = rect(10, 7) b. rect(7, 10) c. [A, B] = rect(7, 10) d. rect(10, 7)// In python // def compute_stats():"""Write a function compute_stats, such that given a string of grades as an input parameter,it calls the function get_new_grades (defined in theprevious question) and returns a tuple that containsthe average value of the initial grades andthe average value after running the get_new_grades function.""" pass
- Programming Language :- C 7. A function is defined for a positive integer n as follows: 3n + 1, if n is odd f(n) = { n if n is even 2 We consider the repeated application of the function starting with a given integer n, as follows: f(n), f(f(n)), f(f(f(n))), It is conjectured that no matter which positive integer n you start from; this sequence eventually will reach to 1. If n = 13, the sequence will be 13, 40, 20, 10, 5, 16, 8, 4, 2, 1. Thus if you start from n = 13, you need to apply function 10 times to reach 1. Write a recursive function that takes n as an input number and returns how many times function f has to be applied repeatedly to reach 1.python nMath: pentagonal numbers) A pentagonal number is defined as n(3n-1)/2 for n=1,2,..., and so on.
