Determine the standard deviation (SD)
The standard deviation of a binomial distribution is calculated as thus:

Substitute values for n and p

Convert to decimals




--- <em>approximated</em>
<em>Hence, the calculated standard deviation is approximately 8.4932</em>
Answer:
It should be the volume of the cylinder.
I'm 85% sure. Hope this is right.
In a triangle the midline joining the midpoints of two sides is parallel to the third side and half as long ⇒
2(3x + 2) = 2x + 20
6x + 4 = 2x + 20
6x - 2x = 20 - 4
4x = 16
x = 16/4
x = 4
midsegment = 3x + 2 = 3*4 + 2 = 12 + 2 = 14
