A new car sells for $30,000. At the end of the season, the dealership advertises 10% off the retail price of the car. What is the sale price in dollars for this car? (Enter an exact number.)

10% off means it will sell for 90% of the original price ( 100%- 10% = 905)

Multiply the price by 90%:

30,000 x 0.90 = 27000

It will sell for $27,000

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
