Answer:
g(x)=(x+7)^2-2
Step-by-step explanation:
The number inside the parenthesis moves the parabola left and right. It didn't move in any of those directions, so 7 stays the same. Since it moved 2 units, 2 goes outside the parenthesis. Since it moved down, you subtract the 2.
Solution :
Let :
X = number of overtime hours
S = total weekly salary
S =
S = 480 + 18X
E(S) =
= 750
Mean of S = 750
Var (S) =
Var(S) =
= 5184
Variance of S = 5184
The standard deviation equals square root of 5184 = 72
