11.) The physics class took two tests. On the first test, the mean score was 72 with a standard deviation of 5. On the second test, the mean score was 80 with a standard deviation of 6. Cindy made an 82 on the first test and an 87 on the second. On which test did she do better relative to the rest of the class?

i got 86 for this

hope this !

if you need an explanation just ask

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
