The random variable W can take on the values of 0, 1, 2, 3, or 4. The expected value of W is 2.8. Which of the following is the best interpretation of the expected value of random variable W ? A A randomly selected value of W must be equal to 2.8.

B The values of W vary by about 2.8 units from the mean of the distribution.

C The mean of a random sample of values selected from the distribution will be 2.8.

D A value of W randomly selected from the distribution will be less than 2.8 units of the mean.

E For values of W repeatedly selected at random from the distribution, the mean of the selected values will approach 2.8.

step-by-step explanation:

.6 is 1/2 of 12

the answer is actually d. i just took the test

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

the answer is 1/4

step-by-step explanation:

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
