Suppose you were hired as a statistical consultant to determine the opinion of the student body as to whether or not they feel the bookstore is purposely overcharging for books. Briefly outline how you would collect data
to answer this question and explain why your process is (or is not) an experiment. If it will be of assistance to
you, assume the campus population is 12,537.

step-by-step explanation:

for the free

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
