A) cost = (cost/gallon)*gallons
.. 83.58 = 3.799*gallons
.. 83.58/3.799 = gallons ≈ 22.001
The SUV has a 22-gallon tank.
B) miles per gallon = miles/gallons
.. miles per gallon = (24297 -24033)/((3/4)*22) = 264/16.5 = 16
The gas mileage for the trip was 16 miles per gallon.
The equation for the line of best fit can be obtained as follows, using the least square method (for more info visit http://hotmath.com/hotmath_help/topics/line-of-best-fit.html ):
mean of X = 1/6
mean of Y = 2/3
slope, m = 704/1121 = 0.6
Computing the y-intercept using the formula:
b = mean of Y - m (mean of X) = 2/3 - (704/1121)(1/6)
b = 0.562 = 0.6
Therefore, the equation of the line of best fit, given the standard relation:
y = mx + b
y = 0.6x + 0.6
the area of the first shape is 4 times 12 which is 48 and the area of the second shape is 2 times 10 which is 20
48+20= 68 mi2
