a base ball glove was on sale for 5/6 of the original price. If the original price was $90, what was the sale price

$75

Step-by-step explanation:

*The new price will be 5/6 of 90*

What will that be? Well, "of" means "multiplication", so multiply 5/6 and 90. Easy way to have 90/1 to balance the fraction

5/6*90/1= 450/6

its 450 because 90*5=450 and 6*1 is 6

now we just divide 450/6 is $75

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
