Answer:
2261.94671
Step-by-step explanation:
You must first find the circumference of the track. Using 2(pi)r.
Where pi=3.14... and r=radius
you can find the radius by dividing the diameter by 2, 120/2=60
Afterwards you input 60 into the equation. 60*(pi)*2= 376.99111843077515
Using that number you multiply it by 6 because she ran the circumference 6 times. 6*376.99111843077515 = 2261.94671
NOTE: The question may require you to simplify at certain times so answers may vary slightly. EX: pi = 3.14, Circumference = 377

Answer:
99.7% data lies between 13 to 43
Step-by-step explanation:
Mean: 
Standard deviation : 
68% of data lies between 
to 
95% of the data lies between 
to 
99.7% data lies between 
to 
We are supposed to find 99.7 of the data will lie between which values
99.7% data lies between 
to 
99.7% data lies between 13 to 43
Hence 99.7% data lies between 13 to 43
