Sam receives a shipment of 36 football helmets. Of the 36 football helmets in the shipment, four of them were scratched and need to be returned. If another shipment of 108 helmets arrive, then how many are likely to be scratched.

12

Step-by-step explanation:

If 4/36 were scratched. 108 is 36 divided by 3 so multiply 4 by 3

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

company a

step-by-step explanation:

using the linear regression models , it is found that company a   pays about $14 more. but using the same regression (linear) company b pays about $10 more.
