I'm pretty sure it is 155
Answer:
Step-by-step explanation:
We have the following properties:
So, if we have that E[X(X-1)] = 27.5, we can write them using the first property as:
Then, replacing E(X) by 5 and solving for , we get:
Finally, using the second property and replacing by 5 and by 32.5, we get that V(X) is equal to:
The unit rate is -1. because the unit rate has to have a denominator of 1.
<u>ANSWER</u>
The correct answer is A
<u>EXPLANATION</u>
Given .
We can find the inverse by taking the steps.
1. Let
2. Interchange x and y
3. Make y the subject
The new function we got now is the inverse of f(x)

Hi there! This is what the graph should look like: (Look at the picture attached)
We can see that the solution to the equation is (3, -2) because this is where the lines intersect.
