Question

A farmer bought some sacks of animal feed. The weights of the sacks are given below in kilograms. What is the average weight of the sacks ?
49.8, 49.7, 49.5, 49.3, 50, 48.9, 49.2, 48.8

Answer 1

Average weight = $\frac{\mathrm{Total}\mathrm{weight}\mathrm{of}\mathrm{all}\mathrm{the}\mathrm{sacks}}{\mathrm{Total}\mathrm{number}\mathrm{of}\mathrm{sacks}}$

$$\begin{gathered} =\frac{49.8+49.7+49.5+49.3+50+48.9+49.2+48.8}{8} \\ =\frac{395.5}{8} \\ =49.4 \end{gathered}$$
Thus, the average weight of the sacks is 49.4 kg.
