The true statement is that only line A is a well-placed line of best fit
<h3>How to determine the true statement?</h3>
The scatter plots are not given. However, the question can still be answered
The features of the given lines of best fits are:
<u>Line A</u>
- 12 points in total
- Negative correlation
- Passes through the 12 points with 6 on either sides
<u>Line B</u>
- 12 points in total
- Positive correlation
- Passes through the 12 points with 8 and 4 in either sides
For a line of best fit to be well-placed, the line must divide the points on the scatter plot equally.
From the given features, we can see that line A can be considered as a good line of best fit, because it divides the points on the scatter plot equally.

You can calculate the arc lenght by using this formula:
arc length = 2π*r*(A/360) , where A=angle of the arc.
So for you it would be:
arc length = 2π*4*(72/360) = 5.03
I hope that helped.

Step-by-step explanation:
Joe pays out $60.03 for a $45.58 item. Subtract: $60.03-$45.58=$14.45.
He should receive $14.45 in change.
