Answer:

(5, 50)

Explanation:

$\textsf{Balance point}=(\overline{x}, \overline{y})$

To calculate the balance point of the data, determine the mean of the x-values and the mean of the y-values.

$\boxed{\sf Mean=\frac{\textsf{sum of all the numbers}}{\textsf{amount of numbers}}}$

x-values: 1, 3, 4, 8, 9.

$\implies \textsf{Mean}\;\overline{x}=(1+3+4+8+9)/(5)=5$

y-values: 30, 50, 20, 90, 60.

$\implies \textsf{Mean}\;\overline{y}=(30+50+20+90+60)/(5)=50$

Therefore, the balance point is (5, 50).
