Clarissa made the box and whisker plot on the left below. When she finished and looked back at the data set, she realized that she had forgotten to include one entry, 35, in her plot. Since 35 is the highest number in the set, Clarissa simply extended the right whisker to make the box and whisker plot on the right. Can Clarissa be sure that her new graph is now correct? Why or why not?

the anwser is d) 75°

step-by-step explanation:

i believe the answer is the polygon, heptagon.

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
