A worker in the automobile industry works an average of 43.5 hours per week. If the distribution is approximately normal with a standard deviation of 1.9 hours, what is the probability that a randomly selected automobile worker works less than 41 hours per week

the answer is mp

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

answer:

24pi or letter c
