Answer 2

Answer: 8 points

Explanation:

Given : Every Friday Vicente has a 10 point quiz in his math class.

His first 7 scores were 7, 9, 9, 6, 9, 8, and 8.

To find : Average quiz score.

We know that average for a data is given by :-

`\text{Average}=\frac{\text{Sum of observations}}{\text{Number of observations}}`

i.e.
`\Rightarrow\ \text{Average}=(7+9+9+6+9+8+8)/(7)`

i.e.
`\Rightarrow\ \text{Average}=(56)/(7)=8`

Hence, his average quiz score = 8 points
