Given the following probability distribution, what is the expected value of the random variable X? X P(X) 100 .10 150 .20 200 .3

Mekhanik [1.2K]

Answer:

d) 205

Step-by-step explanation:

Step(i):-

x : 100 150 200 250 300

p(X=x) : 0.10 0.20 0.30 0.30 0.10

Step(ii):-

Let 'X' be the discrete random variable

Expected value of the random variable

E(X) = ∑ x P(X=x)

= 100 X 0.10 + 150 X 0.20 + 200 X 0.30 +250 X 0.30 + 300 X 0.10

= 205

Final answer:-

The expected value E(X) = 205

Robert earns $8.65 per hour mowing lawns. A) Write a rule for money m as a function of the number of hours h spent mowing lawns.

____ [38]

Answer:

A) $m=8.65h$

B) $29.58

Step-by-step explanation:

Earnings per hour = $8.65

To find:

A) Write a rule for money m as a function of the number of hours h spent mowing lawns.

Earnings done in one hour = $8.65

Number of hours = $h$

To find the total earnings, $m$ as a function of number of hours $h$ , we need to multiply per hour earnings with number of hours $h$ .

Therefore, the equation is:

$m=8.65h$

B) How much does Robert earn if she works 3 hours and 25 minutes?

First of all, let us convert 3 hours and 25 minutes to hours.

3 hours 25 minutes = 3.42 hours

Therefore, total earnings are:

$m = 8.65\times 3.42 = \$29.58$
