The mean/average is found by adding all of your values and then dividing by the number of values found.
7+7+7+7+7+7+7+7+7+7=70
There are 10 size 7 shoes. Divide 70 by 10 to get the mean, which is 7.
Another ex.
Find the average of numbers listed
1+4+8
these add up to 13
there are 3 numbers listed
13/3=4.33 so the mean is 4.33
XY = 17.
Because YW is a perpendicular bisector, we can say that TW and WZ are both equal to 3. It tells us that XZ is 12, so that means that XW must be 12+3 which equals 15.
It also tells us that YW is 8. So we can use the Pythagorean Theorem to find the hypotenuse of Triangle XWY. Thus,

To solve this equation, square and add both of the terms on the right like this:

And then take the square root of both sides. Your final answer should be:
XY = 17.
The percent of the book that the chapter makes up is ten percent
Answer:
15
Step-by-step explanation:
We assume you mean that ...
∠1 + ∠2 = 90°
60° + 2x° = 90° . . . . given values for the angles
2x° = 30° . . . . . . . . . .subtract 60°
x = 15
