Suppose a randomly chosen individuals verbal score X and quantitative score Y on a nationally administered aptitude examination have joint pdf
f(x, y) = 2/5(2x + 3y), 0 ≤ x ≤ 1, 0 ≤ y ≤ 1
Find the covariance and correlation coefficients.

may i see the picture? it would a lot, xox

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2

answer: i feel you honey.
