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
Since the figure is a rhombus, the diagonals cut each other at right-angles and bisect each other, namely cut their vertices in equal halves.
what the dickens does all that mean? well, the angles at vertex C and vertex A are all twins, and therefore, ∡BCA = x, therefore
