I really need help!!! A spinner is divided into 4 sectors of equal size, with the sectors numbered 1 through 4. The probability of the spinner landing on a given sector is the same for all the sectors. The spinner is spun twice, and the results of the spins are added together.

What is the expected value of the sum of the 2 results?

1/2

Step-by-step explanation:

If a spinner is divided into quarters, one section would be 1/4. So, if you spin twice you would get, 1/4 + 1/4 = 2/4 = 1/2

So, your answer would be 1/2

faster, im not sure why but i know it is faster

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.
