So a triangle has a total of 180 degrees
107 + 2x-5 +x = 180
solve for x
112 + 3x = 180
-112 -112
3x = 68
x = 22.6667 degrees
Answer:
True.
Step-by-step explanation:
If we have for a sample of size n=25 a sample variance of 400, the standard error can be written as:

This way of calculating the standard error is the same used for estimating the standard deviation of the sample means for samples of size n=25.

Multiply 20 by 5 to get 100 so multiply the 3 by 5 also to get 15% of the days.
The answer is (5,4). X being the run (5), and Y being the rise (4).
So sale price= normal price-dicount
sale price=100%-20%=80%
therfor
220=80%of origonal price
80%
percent means parts out of 100
80%=80/100=8/10
220=8/10of origonal price
multiply both sdies by 10
2200=8 of origoal price
divide by 8
2200/8=275
origonal price=275
