I'm pretty sure that you need to multiply pie times the radius of the circle
To compare their speed (rate), we need to have the same time or same distance to use as a reference.
Matt ran 50 meters per 10 seconds. Molly ran 30 meters per 5 seconds. If she ran for 5 more seconds, she would have gone 30 more meters, for 30 meters per 10 seconds. Thus, Molly went faster.
Alternately, you could calculate their speeds in meters per (one) second and compare. 50 meters per 10 seconds is 5 meters per second, and 30 meters per 5 seconds is 6 meters per second.
The answer to your Q is 4
Answer:
D.
Step-by-step explanation:
Least value = 22 and greatest = 30
Arrange in order:
22 22 23 23 24 25 26 27 28 30
So the median is the mean of the middle 2:
= (24+25)/2 = 24.5.
Also Q1 = 23 and Q3 = 27
So the correct plot is D.
