Find the mean and standard deviation for
number of siblings.
What percent of the data is within one
standard deviation from the mean? Enter your
answer as a percent XX%.

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:

thats not a system of equations, that is a solution

x= 3^y
