Question

Assume that the number of defective basketballs produced is related by a linear equation to the total number produced. Suppose that 6 defective balls are produced in a lot of 350, and 15 defective balls are produced in a lot of 475.
Find the number of defective balls produced in a lot of 725 balls.

Answer 4

First find what the linear equation

Answer 5

which is

Answer 6

y = mx + b

m = (525 - 400)/(18 - 9)
m = 125/9

Answer 7

ok now find b,

Answer 8

by plugging in one of the points. Y will be the number of balls produced. The equation can also be set up using y as the number of defective balls. That way your m and b will be different.

Answer 9

y = (125/9)x + b
400 = (125/9)(9) + b
b = 275

So the equation is
y = (125/9)x + 275

Answer 10

Now plug in 775 for y

Answer 11

775 = (125/9)x + 275
x = 36

Answer 12

ok now when 775 balls are produced 36 of em will be defective.
