An object that weights 150 pounds on Earth weighs only 57 pounds on Mars.
What percent of an object's weight
on Earth is its weight on Mars?

step-by-step explanation:

(s)he  is right it would be 5.5% because it is smaller than 15.5% or anything smaller than 15.5% in general

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

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
