Answer:

20\pi

Step-by-step explanation:

Circumference formula: 2\pi r

Since the diameter is 20, the radius will be half of the diameter

r=d/2, where d=20

r=20/2=10

C=2\pi r

C=2(10)\pi

C=20\pi

Click the score on the graph where you think the<br> balancing point would be for this data.
Ulleksa [173]

Answer:

The balancing point is 23

<em></em>

Step-by-step explanation:

Given

The above graph

Required

Determine the balancing point

This simply means that we calculate the mean.

From the above graph, we have:

\begin{array}{cc}x & {f} & {21} & {3} & {22} & {5} & {28} & {1} & {29} & {1}\ \end{array}

So, the mean is:

\bar x = \frac{\sum fx}{\sum f}

\bar x = \frac{21*3+22*5+28*1+29*1}{3+5+1+1}

\bar x = \frac{230}{10}

\bar x = 23

<em>Hence, the balancing point is 23</em>
