Answer:
-764.28
Step-by-step explanation:
Given the joint cumulative distribution of X and Y as

#First find
and probability distribution function ,
:

#Have determined the probability distribution unction ,
, we calculate the Expectation of the random variable X:

#We then calculate
:

Hence, the Var(X) is 764.28

Hello! Remember you have to write complete questions in order to find good and exact answers. Here I'll assume that you need a relationship between D and N. So we know some facts:
- As N increases, then D decreases
So this is an inverse relationship. We can write this as:

Since N lies in the denominator, as it increases then D will decrease. So this is a correct relationship
Answer:
D) If WX = XY and XY = YZ, then WX = YZ.
Step-by-step explanation:
The transitive property states that if a=b and b=c, then a=c. So, if two different values equal to the same, separate value, then they are also congruent. The answer choice, d, represents this idea because WX and YZ both equal XY and are shown to be equal.
