Answer 1

The average number of hours spent preparing is;

`3.8\text{ hours}`

Step-by-step explanation:

Given the figure in the attached image.

we want to calculate the average number of hours spent preparing.

`\text{Average = }\frac{\text{ sum of all the data}}{\text{ total number of data}}`

So using the figure provided;

`\begin{gathered} \text{Average =}(2(0)+2(1)+1(2)+1(3)+4(4)+2(5)+4(7))/(16) \\ \text{Average = }(61)/(16) \\ \text{Average = 3.8 (to the nearest tenth)} \end{gathered}`

Therefore, the average number of hours spent preparing is;

`3.8\text{ hours}`
