To determine the Z - score, it is calculated as follows:

Then:

It means that there are more than 3 standar deviations below the advertised mileage.
That's a line:
g(x)=0.5*x-1, pick up some x, and get the y.
For instace: x=0, g(0)=y=-1, x=2, g(2)=y=0.
Two pints are enough for a line.
Step-by-step explanation:
The one point where the lines intersect is one solution. If both points are on the same line it is one solution. If the lines do not intersect it is no solution.
The given polygon has a perimeter of 3 + 5 + 4 + 6 = 18
A similar polygon has sides that are 3 times as big ot 9 + 15 + 12 + 18 = 54
The ratio is 18/54 or 1/3
