You just have to set the denominator to zero and solve for x
Answer:
No
Step-by-step explanation:
This is not a random sample, because Mike only surveyed newly hired police officers.
A random sample would include a mix of different, randomly chosen police officers.
This sample only includes newly hired police officers, so it is not random.
Since each min is 60 seconds you multiply 60 by the number of minutes which is 7 and you get 420:
60x7=420 Then you add 30 seconds equaling 450 seconds total
Then you divide 450 by 4 since she ran 4 laps.
So, Stephanie ran 112.5 seconds per lap
