Each front tire on a particular type of vehicle is supposed to be lled to a pressure of 26psi. Suppose the actual air pressure in each tire is a random variable X for the right tire and Y for the left tire, with joint pdf f(x, y) = K(x^2 + y^2) 20 ≤ x ≤ 30, 20 ≤ y ≤ 30
Calculate the correlation coefficient and discuss

what is the approximate angle of acb if abc is 25cm and the length of segment bc is 15

step-by-step explanation:

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
