A survey of 900 households revealed that 300 had only a tv, 200 had only a computer, and 100 had neither a tv nor a computer. How many households have both a tv and a computer? Use a two-loop Venn diagram to find your answer.

i believe the answer is the polygon, heptagon.

5+(-5)=0, or 5-5=0

3/20

step-by-step explanation:

well, there are 20 outcomes, and 3 of them you want. so, 3/20

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.
