The amount a babysitter charges for babysitting services per hour is shown in the table below. What is the rate of change and what does it represent? What is the y Intercept and what does it represent?

y=8x+2

Step-by-step explanation:

the slope is 8 and the y intercept is 2

the slope is 8 dollars the increase of the price per hour. the yintercept is the amount she get for 0 hours (2 dollars)

1,10

2,18

8/1 is 8

10=8*1+b

10=8+b

2=b

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

it’s supposed to be -4+45=41
