Please complete proofs fully.

Prove true or false. For each natural number n, ((n5/5)+(n^4/2)+(n^3/3)-(n/30)) is an integer

For any nonnegative integer n, let Y1 < Y2 < · · · < Y2n+1 be...

For any nonnegative integer n, let Y1 < Y2 < · · · < Y2n+1 be the ordered statistics of 2n + 1 independent observations from the uniform distribution on [−2, 2]. (i) Find the p.d.f. for Y1 and the Y2n+1. (ii) Calculate E(Yn+1). Use your intuition to justify your answer.

Prove that if n is an integer and n^2 is even the n is even.

The factorial of a nonnegative integer n is written n! (Pronounced “n factorial”) and is defined as follows: n! = n.(n-1). (n-2).……...1 (for values of n greater than 1) n!=1 (for n = 0 or 1) For instance, 5! = 5.4.3.2.1 which is 120. Write a Python program that reads a nonnegative integer n and calculates and prints its factorial. Your program should display a suitable error message if n entered as a negative integer. Figure 6. Exercise 6 ...

Prove that 1^3 + 2^3 + · · · + n^3 = (1 + 2 + · · · + n)^2 for every n ∈ N. That is, the sum of the first n perfect cubes is the square of the sum of the first n natural numbers. (As a student, I found it very surprising that the sum of the first n perfect cubes was always a perfect square at all.)
