Answer:
The balancing point is 23
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:
[tex]\begin{array}{cc}x & {f} & {21} & {3} & {22} & {5} & {28} & {1} & {29} & {1}\ \end{array}[/tex]
So, the mean is:
[tex]\bar x = \frac{\sum fx}{\sum f}[/tex]
[tex]\bar x = \frac{21*3+22*5+28*1+29*1}{3+5+1+1}[/tex]
[tex]\bar x = \frac{230}{10}[/tex]
[tex]\bar x = 23[/tex]
Hence, the balancing point is 23
