Answer:
6
Step-by-step explanation:
Solve the absolutes: |-6| becomes 6
and |6| doesn't change and still is 6
Substitute: 6-6-(-6)
- * - = +
6-6+6 = 6
Answer:
angle BED and angle DEB are the answers.
Answer:
(D) I think
Step-by-step explanation:
Lets look at our answer choices; A.
The intervals are not comparable. The shorter bar spans more than 10 years. When it comes to a horizontal axis it doesn't matter how far it expands,just if it's expanded correctly.
B.The intervals are appropriately labeled. There not it goes from 25 to 50 in just in instant few climbs up.
C.The intervals are not comparable, but the data on the graph is not misleading. It is misleading the graphs are incorrectly labeled.
Which brings us to our answer D.The vertical axis does not have an appropriate scale. it goes from 0-25 25-50 and 50-75 then 75-100. that's a short distance for such numbers that are pretty far apart.
I hope I'm right and I hope this helps:)!
Answer:
a) 
And replacing we got:
b) 
And then the expected value would be:
Step-by-step explanation:
We assume the following distribution given:
Y 0 1 2 3
P(Y) 0.60 0.25 0.10 0.05
Part a
We can find the expected value with this formula:
And replacing we got:
Part b
If we want to find the expected value of 
we need to find the expected value of Y^2 and we have:
And replacing we got:
And then the expected value would be:
The answer is b.
This is because the line is sloping downwards, and so y = -1
