Answer:
1. 1340
2. Variance = 47200, standard deviation = 217.25556
Step-by-step explanation:
1-
If X is the random variable that give the number of admissions, then the expected number of admissions<em> E[X]</em> for the fall semester is
1080*P(X=1080)+1380*P(X=1380)+1540*P(X=1540) =
1080*0.4+1380*0.1+1540*0.5 = 1340
2-
The <em>variance</em> is defined as
We have
whereas
So the variance equals
The <em>standard deviation is just the square root of the variance</em>, so, the standard deviation is

Answer:
OP = 3 units
Step-by-step explanation:

15 + OP = 18
OP = 18 - 15
OP = 3 units
