A cell phone company checks a shipment of 200 phones and finds that 5 are defective. Based on this data, about how many defective phones should the company expect to be defective in a shipment of 760 phones?

20

Step-by-step explanation:

There are 15 in 600. There would then be 2.5 for 100, but we round that to 3. There are 1 per every 40 in 200, so we have 19. We have 20 left, and could expect at least one, so it is 20. :)

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
