Which of the following does not belong to the solution set of -3x + 7 < 11? 4 -1 -5 0

-5

Step-by-step explanation:

We can just see what x has to be smaller than (or plug in the numbers, but that is more time-consuming).

-3x + 7 < 11 -> -3x < 4 -> x > -4/3

-5 is the only number that is less than or equal to -4/3.

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 4th choice is the correct one
