The height of figure A is 9 feet. The height of a similar figure B is 15 feet. What is the ratio of the perimeter of A to the perimeter of B?

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

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead
