For this case we are going to assume the following:
m: whole number greater than zero.
n: integer greater than zero.
Where,
n> m
According to these assumptions, the percentage of growth is given by the following formula:
Answer:
the number of students did grow by:
<h3>
Answer: B) 2.9 approximately</h3>
==================================================
Explanation:
The weird or fancy looking E symbol is the greek uppercase letter sigma. It is effectively the english version of S to represent summation. So we add up all the 
terms to get this. Luckily this has already been done for us in the table where they wrote "sum = 34", so 
From here, we substitute this into the formula, along with n = 5 since there are 5 items in the original list
So,
This computes the sample standard deviation. To get the population standard deviation, you'd basically change the "n-1" to simply "n", and the rest of the formula is identical.
Answer: 3 x 5^2 x 7
525 / 3
= 175
175 / 5
= 35
35 / 5
= 7
7 / 7
= 1
Therefore,
3 x 5^2 x 7
