An insurance actuary tracks the customer mass and the dosage of a certain medicine prescribed to customers. An approximate least-squares regression line was used to predict the dosage, in milligrams,
from a given customer mass, in kilograms.
600

Dosage (milligrams)

Interpret the residual for the customer indicated in the scatterplot above.

answer: plz give a pic and answer choices so i can answer!

step-by-step explanation:

a.) list the factors of 40.

1/2/4/5/8/10/20/40

b.) list the factors of 40 that represent the number of cans that could be on each shelf.

5

c.) how many different arrangements of cans are possible?

just one because if you put more on one shelf you will go way over 40 and the cabinet will probably break.

d.) what are the possible arrangements of the cans?

put 5 cans on each self to reach 40 cans in total.

e.) which arrangement uses all the shelves?

5 because you can put 5 cans on each shelf, and since there are 8 shelfs you are equally going to get 40 cans.

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.
