The Line graph shows the number of marks Stacey scorer in her homeworks.

weqwewe [10]

<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

$(0\times 4)+(1 \times 5)+(2\times 3)+(3\times 4)+(4 \times 3)+(5 \times 1)$

Simplifying, we get;

$0+5+6+12+12+5=40$

Thus, the total number of marks is 40.

Sum of the number of marks scored is given by

$4+5+3+4+3+1=20$

Thus, the sum of the marks scored is 20.

The mean is given by

$Mean=\frac{40}{20}$

$Mean=2$

Therefore, Stacey's mean score is 2 marks.
