According to the US Census Bureau's American Community Survey, 78%, percent of Americans over the age of 25 have earned a high school diploma. Suppose we are going to take a random sample of 100 Americans in this age group and calculate what proportion of the sample has a high school diploma. The mean of the sampling distribution of the proportion is

answer: you need to organize this better it does not make sense.

step-by-step explanation: ?

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
