Mathwords: Expected Value. A quantity equal to the average result of an experiment after a large number of trials. For example, if a fair 6-sided die is rolled, the expected value of the number rolled is 3.5. This is a correct interpretation even though it is impossible to roll a 3.5 on a 6-sided die.

Answer:

5.5; 11.00; 16.50

$E = 5.5h$

Step-by-step explanation:

Given

The attached table

Solving (a): Complete the table

First, calculate the slope (m)

$m = \frac{E_2 - E_1}{h_2 - h_1}$

So:

$m = \frac{27.5- 22.00}{5-4}$

$m = \frac{5.50}{1}$

$m = 5.50$

So, the equation of the table is:

$E = m(h - h_1) + E_1$

$E = 5.5(h - 4) + 22$

$E = 5.5h - 22 + 22$

$E = 5.5h$

When h =1,2,3

$E = 5.5 * 1 = 5.5$

$E = 5.5 * 2 = 11.00$

$E = 5.5 * 3 = 16,50$
