Distance traveled = 70 m
Number of rotations = 29
We know, Circumference * Number of rotations = Distance traveled
So, C = 70 / 29
C = 2.41 m
Now, we know, diameter = C / π
So, d = 2.41/3.14 = 0.768
In short, Your Answer would be: 0.8 m
Hope this helps!

Answer:
Hypothesis testing of ' significance of difference between means'
Step-by-step explanation:
Study conducted to tests whether oxygen level prior SAT score improves test score. This can be done through - Hypothesis testing of ' significance of difference between means'.
Where x1 & x2 represent mean values of SAT test score before (or without) & after (or with) oxygen.
Null hypothesis [H0] = x1 = x2 , Alternate Hypothesis [H1] : x1 < x2
The answer is y=(1/20)x^2
