This is just to apply a simple formula.
The formula is variance is the squared standard deviation.
Call variance v and standard deviation s => v = s^2
Here s = 8 => v = 8^2 = 64
Answer: 64

The number is 40
<u><em>
Explanation:</em></u>
Assume that the number we are looking for is x.
We know that 55% of the number x is 22.
This means that:
55% of x = 22
55% * x = 22
0.55x = 22
<u>Now, we will simply solve for x as follows:</u>
0.55x = 22
x = </span>

x = 40
