A dress that costs x dollars is on sale for 25% off. Which expressions represent the sale price, in dollars, of the dress? Select all that apply.

The answer is 0.75x.

Step-by-step explanation:

If the dress is on sale for 25% off, then we know that the new sale price of the dress is x - (25/100)x = x - 0.25x = 0.75x.

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
