8/11 is the fraction
To derive this simply put
72.727272/100 and it reduces to 8/11
C = 3.5t....when t = 15
c = 3.5(15)
c = 52.50 <==
Sin Q = oppo. / hypo
sin Q = 9/15
sin Q = 0.6
The answer is 10 :) ........
If I understand what you are asking, you can use the median as an average since it is not affected by the mean ( median is a measure of center). Since a mean is affected by outliers, it might lower the score if there are very low outliers. But note that if there are outliers way <em>greater </em>it can increase the average. You can use the Inter Quartile Range if shown on a box plot ( measure of variability).
