Question

The mean length of 7 sticks is 1.02 m. What is the total length of the sticks?

Answer 1

The Solution:

Given:

`\begin{gathered} mean=1.02m \\ number=7\text{ sticks} \end{gathered}`

By formula,

`mean=(total)/(number)`
`\begin{gathered} 1.02=(total)/(7) \\ \\ Cross\text{ multiply to get:} \\ \\ total=7*1.02=7.14m \end{gathered}`

Therefore, the correct answer is 7.14m
