Answer 2

Answer:  8 points

Step-by-step 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 :-

$\text{Average}=\dfrac{\text{Sum of observations}}{\text{Number of observations}}$

i.e. $\Rightarrow\ \text{Average}=\dfrac{7+9+9+6+9+8+8}{7}$

i.e. $\Rightarrow\ \text{Average}=\dfrac{56}{7}=8$

Hence, his average quiz score = 8 points
