Answer:
Step-by-step explanation:
The circumference formula is
where r is the radius
The circumference of the NAVY Pier Wheel is 439.6
We know the circumference so we solve for r.
So our radius is 70.
The circumference of Navy is 56% of the original wheel. So we can just set up a proportion.
to find the new circumference.
We simplify that and we get y=485
Know we find the radius,
r=
So our radius is 125.
3. The first Ferris wheel circumference is 785. We divide 9 by that to find the wheel movement per minute.
785/9= 87.2 feet per minute

Answer:
Step-by-step explanation:
Sampling error occurs when the sample used by the research is not a representative of the whole population. While a non sampling error occurs during data sampling due to other factors than taking a sample.
Since there were no errors in collecting the data during day sampling, and it is safe to assume that the sample taken was a representative of the population, we can conclude that this is a non sampling error that was due to other factors than taking a sample.
