For this case, what you must do is pass all the averages to the same unit of measurement in order to make the comparison between the three batters.
We have then:
Sue = 0.426
Heidi = (12/15) = 0.8
Selena = (47.5 / 100) = 0.475
answer
the highest batting average was for Heidi with an average of 0.8
1.53 rounded to the nearest tenth is 1.5
You find the circumference of a full circle so 2πr =43.98
then divide by 4=10.995
so the answer is 10.995cm
100 is the y intercept so its graohed at (0,100)(y-axis) and it goes up every 1/55
