There was a study done that found that 21% of people have returned a piece of clothing after they have worn it. If I speak to 20 people: a. How many people would I expect to have worn a piece of clothing and returned it?

b. What is the probability that exactly 6 of the 20 people have worn a piece of clothing and returned it?

c. What is the probability that at least one person has worn a piece of clothing and returned it?

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.

step-by-step explanation:

step-by-step explanation:

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!
