Answer:
<em></em><em></em>
<em></em>
Step-by-step explanation:
Given
Required
The standard deviation
First, calculate the expected value E(x)
So, we have:
Next, calculate E(x^2)
So, we have:
The standard deviation is:
<em></em><em> --- approximated</em>
Answer:
G is the answer
Step-by-step explanation:
You have to subtract the two angles from 180, the total angle to get the third one.
Solve for h by simplifying both sides of the equation, then isolating the variable.
h=a/2+1-3/a
