Answer:
Step-by-step explanation:
For this case we have the following distributions given:
The expected value for x is
And the variance
The expected value for x is
And the variance
We define a new random variable:
We need to find the expectd value and the variance for W.
For the expected value we have this:
And if we replace the parameters we got:
Now foe tha variance of W we know that X and Y are indpenendet variable so then
For this case we can use the property that is a is a constant and X a random variable then , and we got this:
And if we replace we got:
Answer:
The y-value of Point A is 1.
Step-by-step explanation:
Because Point A only went up one (1) the coordinate plane.
Answer:
A
Step-by-step
because the variable is squared you have to find the square to simplify it.
