<span>Use mathematical induction to prove the statement is true for all positive integers n, or show why it is false.

2.12 + 42 + 72 + ... + (3n - 2)2 = quantity n times quantity six n squared minus three n minus one all divided by two.

I hope my answer has come to your help. God bless and have a nice day ahead!

Juli2301 [7.4K]

First we define the varible to use:
x = represent the number of cookies
Cameron:
The amount of cookies he made was:
x
Deyonne:
We can rewrite the amount in different ways:
x + 0.25x
1.25x
Then, the total revenue is:
0.50 * (x + (x + 0.25x))
We rewrite:
0.50 * (x + 1.25x)
0.50 * (2.25x)
Answer:
The following expressions represent possible revenue from the sales:
F. 0.50 (2.25x
C. 0.50 (x + 1.25x)
A. 0.50 [x + (x + 0.25x)]

A box contains 12 balls numbered 1 through 12.

Also the ball are drawn without replacement.

The probability that the first ball had a smaller number on it.

i.e. the number on the first ball could be: {1,2,3}

Hence, the probability that the first ball had a smaller number on it is:

$\dfrac{3}{12}=\dfrac{1}{4}=0.25$
