Answer:
. Let fX,Y(x,y) = 10xy^2 for 0 < x < y < 1 be the joint density function of the random pair (X, Y). (a) Obtain the marginal density f(y) of Y. (b) Obtain the conditional density fx|y(x|y) of X given Y = y. (c) Evaluate the conditional expectation of X, given Y=y
Y = y.
Step-by-step explanation:
Answer:
its -1/4
Step-by-step explanation:
The surface area formula is
π
π
.
Using the formula, you can determine that the answer is C.
C because i took the test
Time=distance/speed
distance=5 miles
speed= 10 mph
5/10=1/2
so the answer would be 1/2 hour / 30 minutes
