please thank if you learned from this answer.
B
Standard deviation is the average distance away from the mean, thus B is correct
1. Option A
2. Option B
I would like to elaborate on the answer to the second question, since the first answer is actually option a. Why? The question asks for a parametric equation, not set, so it would be choice a.
2. x=3t + 5 - isolate t

y = [(x-5)/3]^2 - 1
your solution is option b
b is correct for Maria but c is correct for the boy
