Answer:

=50.29

Step-by-step explanation:

The perimeter of a circle is also called the circumference

C = 2 * pi *r

25 1/7 = 2 * 22/7 *r

Rewriting as an improper fraction on the left

(25*7 +1)/7 = 44/7 *r

176/7 = 44/7 r

Multiplying each side by 7/44

7/44 *176/7 = 7/44 *44/7 r

4 = r

We can now find the area by

A = pi r^2

A = (22/7) * 4^2

A = 22/7 * 16

  =352/7

Rounding to the nearest hundredth

  =50.29

What is the maximum value that a marginal relative frequency can be? Explain.
mart [117]
The maximum value it can be would be 100%.  The only times that it could be this high is when there is only a class on the frequency distribution table.  Another way, is that there is only one column variable on the table (& or if there is only one row.)  Any other time is will be less, but the maximum stays 100%.
