A package delivery company experiences high variability in daily customer demand, which in turn results in high variability in t
Ilya [14]

Solution :

Let :

X = number of overtime hours

S = total weekly salary

S = $12 \times 40 + 18 \times X$

S = 480 + 18X

E(S) = $480 + 18 \times E(X)$

$E(S) = 480 + 18 \times 15$

        = 750

Mean of S = 750

Var (S) = $18^2 \times Var(X)$

Var(S) = $18^2 \times 4^2$

          = 5184

Variance of S = 5184

The standard deviation equals square root of 5184 = 72

In ΔCDE, the measure of ∠E=90°, the measure of ∠C=70°, and DE = 12 feet. Find the length of CD to the nearest tenth of a foot
Radda [10]

Answer:

CD = 4.4ft

Step-by-step explanation:

Given

DE = 12

\angle C = 70^\circ

Required

Find CD

This question is represented with the attached triangle

To solve CD, we make use of tan formula.

tan(70) = \frac{DE}{CD}

Substitute 12 for DE

tan(70) = \frac{12}{CD}

Make CD the subject

CD = \frac{12}{tan(70)}

CD = \frac{12}{2.7475}

CD = 4.4ft --- approximated
