Answer:
The value of E(Y/X) is 2.
Step-by-step explanation:
As the complete question is not given, thus the complete question is found online and is attached herewith.
So the joint density function is given as

So the marginal function for X is given as

Now

Now the value of E(Y/X) is given as

So the value of E(Y/X) is 2.
Answer:
x = -16
Step-by-step explanation:

Either C or B because your credit helps alot with your home and also helps with credit cards. I'm leaning more towards C though.
ANSWER
The coordinates of the image are (2,2)
EXPLANATION
The mapping for a reflection across the line y=k is :

We want to find the image of the point (2,-4) after a reflection in the line y=-1.
In this case k=-1.

This simplifies to,


Hence the image is (2,2)
