50 credit card holders are randomly selected and the amounts they currently owe are recorded. The researchers then find the mean and median. The largest data value (550,000) in the set is then replaced with $1,000,000 and the statistics are
calculated again.
A) What type and how much of an effect will this change have on the mean?
B) What type and how much of an effect will this change have on the median?

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
