John's friend told him that he could earn $49 for handing out flyers at a local concert. john wants to calculate the hourly rate. if he works a total of 3.5hours, the equation 3.5x=49 can be used to determine his hourly rate. what would johns rate be, in dollars?

 John's rate = $14

Step-by-step explanation:

Given: John's friend told him that he could earn $49 for handing out flyers at a local concert.

If he works a total of 3.5 hours, the equation can be used to determine his hourly rate x.

Divide 3.5 on both the sides of the equation, we get

Therefore, John's rate = $14

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

14
