Melanie stopped to get gas for her car before beginning a trip. her odometer
read 42,587 miles, and she filled up her tank with 22 gallons. at the end of her
trip, her odometer read 42,895 miles. what is her car's miles per gallon?

The rate of car is 1949.7727 miles per gallons   .

Step-by-step explanation:

Given as :

The reading of odometer before filling gas = r = 42,587 miles

The reading of odometer after filling gas = R = 42,895 miles

The quantity of gas filed up inside tank = q = 22 gallons

Let The rate of car's miles per gallon = r

Now, According to question

The rate of car's miles per gallon =

i.e r =

Or, r =

Or, r = 1949.7727  miles per gallons

So, The rate of car = r = 1949.7727 miles per gallons

Hence, The rate of car is 1949.7727 miles per gallons   . Answer

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
