Let x denote the number of broken pencils in a randomly selected 50-count box from a local office supply store. The variable x has the following probability distribution: x01234 P(X)0.520.350.10.020.01 Calculate and interpret σx.

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
