Rosie placed 8 red counters and 6 counters of other colors into a bag. She drew a counter from the bag, recorded the color, and placed the counter back into the bag before drawing again. She did this process 60 times and recorded she drew a red counter 32 times and another color 28 times. Based on her experimental data, what is the probability she will draw a red counter on the next draw? A 7/15 B 13/15 C 8/15 D 5/8

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?
