The factorial n! of a positive number (integer) is defined by n! = n · (n – 1) · (n – 2 ) ...- 3· 2·1, where 0! = 1. Write a user-defined function that calculates the factorial n! of a number. For function name and arguments, use y=fact(x), where the input argument x is the number whose factorial is to be calculated and the output argument y is the value x!. The function displays an error message if a negative or non-integer number is entered when the function is called. Do not use MATLAB built-in function factorial. Use fact with the following numbers: (а) 9! (b) 8.5! (c) 0! (d) -5!

Write a program that takes as input five numbers and outputs the mean (average) and standard deviation of the numbers. If the numbers are x1,x2,x3,x4,andx5, then the mean is x=(x1+x2+x3+x4+x5)/5 and the standard deviation is: s=(x1x)2+(x2x)2+(x3x)2+(x4x2)+(x5x2)5 Your program must contain at least the following functions: a function that calculates and returns the mean and a function that calculates the standard deviation.

Please provide solution in C++: Write a function MaxMagnitude with two input parameters, that returns the largest-magnitude value. If the inputs are 5 7, the function returns 7. If the inputs are -8 -2, the function returns -8. (Note: The function does not just return the largest value, which for -8 -2 would be -2). Though not necessary, you may use the absolute-value built-in math function. Use the function in a program that takes two integer inputs, and outputs the largest-magnitude value. #include <iostream>using namespace std; int main() { //int MaxMagnitude; int userVal1; int userVal2; { if(abs(userVal1)>abs(userVal2)) return userVal1; else return userVal2; }

Your function must also return the number of terms necessary to reach this error, that is, your function will return a tuple with the two calculated values. Important: It is mandatory to use the function defined in the previous item. Hint: math.fabs(number) returns the absolute value (module) of a number.

Write a function ones_and_tens_digit_histogram(numbers) that takes as input a list of numbers and produces as output a list of 10 numbers. Each element of the result indicates the frequency with which that digit appeared in the ones place or the tens place in the input. here is an example call and result: Call: ones_and_tens_digit_histogram([0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597, 2584, 4181, 6765]) Return: [0.21428571428571427, 0.14285714285714285, 0.047619047619047616, 0.11904761904761904, 0.09523809523809523, 0.09523809523809523, 0.023809523809523808, 0.09523809523809523, 0.11904761904761904, 0.047619047619047616] In this example call, the index 1 of the list contains the element 0.14285714285714285 because the value 1 appears in 14.285714285714285% of the ones or tens digits of the given numbers. In a number that is less than 10, such as 3, the tens place is implicitly zero. That is 3 must be treated as 03. Your code should treat the tens digits…
