Answer:
C -36
Step-by-step explanation:
2/3 c = d
multiply both sides by 3/2:-
c = (3/2) d
Well you have to go $33.95 x 7.25 and that will be your answer. Do it fast!
a.

is a proper joint density function if, over its support,
is non-negative and the integral of
is 1. The first condition is easily met as long as
. To meet the second condition, we require

b. Find the marginal joint density of
and
by integrating the joint density with respect to
:


Then


c. This probability can be found by simply integrating the joint density:
