1 36.86 1360.9
We are supposed to find mean and standard deviation
Mean =
Standard deviation =
Just do 7/4 and cross multiply with 1/2
Let us draw a triangle ABC with A=15° ,B=113° and b=7.
Please see the attached image.
We know that the sum of interior angles of a triangle is 180 degrees. Thus, we have

Apply Sine rule in the triangle ABC, we get

Therefore, we have

Well for starters 10% of 120$ is 12$. 120+12=134...
This means 140 - 134=6
Answer: $6 of change
