Lets get started :)
Diameter = 2.5 ft
Radius =
a) The Circumference formula of a circle is given in the picture below, we can plug-in the given information
C = 2
(1.25) or 2.5
≈ 7.85 ft
(we can leave the answer in terms of pi {})
b) We divide the total number of distance the tire will travel by the circumference to find how many times the tire will roll
(I have used the value in feet because we found the circumference in feet units and notice that I took the value of circumference to be 2.5 instead of 7.85, to increase accuracy)
672.2
The tire will rotate 672 times (a tire cannot roll a decimal times, so we take to the nearest whole number) to travel 1 mile

The attached graph represents the scatter plot of the table of values
<h3>How to create the scatter plot?</h3>The table of values is given as:
Variable A 1 4 2 3 5 1 3 7 6 6 2 9 7 5 8
Variable B 6 6 1 6 7 4 4 7 5 3 5 25 21 4 4
Rewrite the table as:
x 1 4 2 3 5 1 3 7 6 6 2 9 7 5 8
y 6 6 1 6 7 4 4 7 5 3 5 25 21 4 4
Next, we plot the values on a graph
See attachment for the scatter plot
