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!!!

first off what is to the power of eight? If its 12 then see part 1 is its the whole thing then see part 2.

Step-by-step explanation:

1. 5x+12^2=

5x+144=

x=28.8

2.( 5x+12)^2

    5x^2+12^2(cancel out the power of 2 since it has no effect on the expression)

    5x+12

     x=2.4
