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
1.25 would be your answerrr
I don't understand this at all.... can you be a little more clear please??
The angles have equal measure because they are vertically opposite angles.
3x + 50 = 6x - 10
3x - 6x = -10 - 50
-3x = -60
x = 20
The answer is x=20.
