What are the related frequencies to the nearest hundredth of the columns of the two way table? group 1: a-102 b-34group 2: a-18 b-14edited: i don’t have all day to be waiting for an answer. i figured it out.

Use mathematical induction to prove the statement is true for all positive integers n, or show why it is false. 1^2 + 4^2 + 7^2 + + (3n - 2)^2 = [n(6n^2-3n-1)/2]

Which shows one way to determine the facts of x3+4x2+5x+20 by grouping
