Which of the following number lines represents the solution to x-5>-2

see below

Step-by-step explanation:

x-5 > -2

Add 5 to each side

x-5+5 > -2+5

x > 3

open circle at 3 line going to the right

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
