The joint density function for a pair of random variables X and Y is given. (Round your answers to four decimal places.) f(x, y) = Cx(1 + y) if 0 ≤ x ≤ 2, 0 ≤ y ≤ 6 0 otherwise (a) Find the value of the constant C. (b) Find P(X ≤ 1, Y ≤ 1). (c) Find P(X + Y ≤ 1).

yes.. it's proven to be 36.

134.6 us dollars

step-by-step explanation:

1 us dollar = 1.33 canadian dollars

so, 150 us dollars = 150 × 1.33 = $199.5.

in canada, the money mitchell spent = 20 canadian dollars.

remaining canadian dollars with him = 199.5 - 20 = 179.5.

after mitchell returned to us, he exchanged the remaining canadian dollars to us dollars.

179.5 canadian dollars = 179.5 × 0.75 = 134.6 us dollars.
