<u>Given</u>:
The line graph shows the number of marks Stacey scored in her homeworks.
We need to determine the Stacey's mean score.
<u>Mean score:</u>
The total number of marks is given by

Simplifying, we get;

Thus, the total number of marks is 40.
Sum of the number of marks scored is given by

Thus, the sum of the marks scored is 20.
The mean is given by


Therefore, Stacey's mean score is 2 marks.
50 + (50 * 0.065) = the answer, sorry I don't have my calculator on me.
Answer:
