Answer:

x = 45

Step-by-step explanation:

Corresponding sides of similar triangles will be in same ratio.

$\dfrac{x}{x+18}=\dfrac{20}{28}$

Cross multiply

x*28 = 20*(x+18) {Use distributive method}

28x = 20x + 360

28x - 20x = 360

8x = 360

x = 360/8

x = 45

Answer:

The expected value for the random variable is 14.16.

Step-by-step explanation:

We are given the following data below;

Z P(Z) $Z \times P(Z)$

9 0.16 1.44

12 0.25 3

15 0.36 5.4

18 0.17 3.06

21 0.06 1.26

Total 1 14.16

Now, the expected value for the random variable Z is given by;

E(Z) = $\sum Z \times P(Z)$

= $(9 \times 0.16) + (12 \times 0.25) +......+(21 \times 0.06)$

= 14.16.
