When creating a bar graph to represent data, the researcher used a scale that was too small. the outcome was a graph that appeared to show very little variation. this is a classic example of an error in which phase of inferential statistics? a. data gathering b. data organization c. data analysis d. probability-based inference

b

step-by-step explanation:

u take $75 minus $60.the anwer/original($75)multiply by 100

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
