Answer 8

Mean is the average of the set of numbers
Mean can be found by using the equation:
\[Mean=\frac{\sum x}{n}\]
Where:
\(\sum x\) is the number you get when you add up all the numbers
\(n=\) is the number of itmes there

In this case:
\[\sum x= 3+ 1+ 9+5+ 9+ 6+ 9\]\[\sum x=42\]\[n=7\]
Sub these values into the equation:
\[Mean=\frac{\sum x}{n}\]\[Mean=\frac{42}{7}\]\[Mean=6\]
