Tim has kept the following record of his water bills. what is the average? january february march april may june $48.28 $58.58 $51.35 $58.28 $53.45 $55.26

$54.2

Step-by-step explanation:

Average or mean of the data is the exact center point of the data. It basically shows the middle point of the data set so that one can estimate the nature of the data. The formula to calculate the mean is:

Mean = Sum of all observations / Number of observations.

Substituting the values gives:

Mean = (48.28+58.58+51.35+58.28+53.45+55.26)/6

Mean = 325.2/6

Mean = 54.2

So the average of the water bills is $54.2!!!

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
