Answer:
Reference angles are always acute.
We can find the reference angle with the "formula"
π
−
θ
, where
θ
is our given angle.
We can plug

into our expression to get

Thus, our reference angle is

Answer:
Range =94
σ² = 1,141.564
Standard Deviation = 33.78703
Step-by-step explanation:
First off to find the range, we find the highest value and subtract it to the lowest value. In this situation the values are:
Highest = 99
Lowest = 5
Range = 99 - 5
Range = 94
Now to find the variance of the sample data set, we first need to find for the mean of the data.
The mean of the data with be the sum of all the numbers in the data set divided by the number of samples.
5 + 14 + 26 + 50 + 60 +72 + 79 + 88 + 93 +94 + 99
That would equal 680
Then you divide the number of samples and that is 11 so the next equation is 680 divided by 11
So the then-
Mean = 61.81818
Now to find the variance we simply use the formula:
Now to find the variance we simply use the formula:
σ²=
σ²=
σ²=
σ²=
Now to find the standard deviation, we take the variance and get the square root of it.
Standard Deviation= 
Standard Deviation= 
HOPE THIS HELPS :)
Answer: 34
Step-by-step explanation: you would have to add 14 to the other side. In math you have to do the opposite to cancel out sides. So to cancel -14 you would have to add 14 to -14 (making it zero) and 20 (making it 34)
Im bad at explaining but I hope you now kindof get it
