Peter attempted to use the divide-center method to find the line of best fit on a scatterplot.
what was his mistake?
he had a different number of points to the left of the vertical line than to the right of the vertical line.
he had a different number of points above the line of best fit than below the line of best fit.
he didn’t approximate the center of the cluster located on the left side of the vertical line and of the cluster located on the right side of the vertical line.
he didn’t connect the centers of the clusters on the left side and right side of the vertical line to produce the line of best fit.

The school track has eight lanes. each lane is 1.25 meters wide. the arc at each end of the track is 180. the distance of the home straight and the radii for the arcs in the 1st 4 lanes are given. s=85m r1=36.5m r2=37.75m r3=39m r4=40.25m part one: find the radii of lanes 5 through 8 of the track. show your work. part two: if max ran around lane one, how far did he run? show your work and explain your solution. part three: max wants to run a total of three laps around the track, choose two additional lanes (2-8) for him to run and find the distance around those two lanes. show your work and round to the hundredths. part 4: based on your lane choices in part three, what was the total distance max ran in the three laps around the track?
