In honor of Prince/the artist formally known as Prince, you create a playlist of 16 of his greatest hits. Let Xi be the length of the ith song (in seconds) on the playlist. Assume that each Xi is distributed by a uniform random variable between 394 and 406 seconds, independent of the length of the other songs. Use the Central Limit Theorem to approximate the probability that your playlist of 16 songs is between 6000 and 6440 seconds long.

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

both triangles are similar because 2 is just smaller than the big one 1 is similar because they are facing different way's but are similar to each other
