I had this question so here's the answer and explanation! :)
Answer:
The answer to your question is the first option :D
Step-by-step explanation:
Original expression
-3/8 (-4 + 1/2)
First option -3/8 (-4) + (3/8)(1/2) This option is not equivalent because
they forgot the negative sign of the
second term.
Second option (-3/8)(-4) + (-3/8)(1/2) This option is equivalent to the
original. Distributive property
Third option (-3/2)(-3 1/2) This option is equivalent to the original
Fourth option (-3/8)(-3) + (-3/8)(-1/2) This option is equivalent to the original

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:
16 feet in length.
Step-by-step explanation:
In this situation, you are given the area and the width of the full carpet, furthermore, you must reverse the formula for area to find the length, as so:

<em>l</em> = 136 ÷ 8.5
<em>l</em> = 16 feet
