Let S={1,2,3,4,5,6,7,8} be a sample space with P(x)=k2x where x is a member of S,
and k is a positive constant. Compute E(S). Round your answer to the nearest hundredths.

step-by-step explanation:

c > -10.55

step-by-step explanation:

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
