Sagot :
The weighted mean should be 85.
Given that,
- There are 2 midterms of 15% each.
- Homework - 10%.
- Projects - 5%.
- Attendance - 10%.
- Final - 30%.
- Scores of midterm 1 = 85.
- Scores of midterm 2 = 90.
- Scores of final - 80.
- Scores of homework - 95.
- Scores of project - 100.
- Scores of attendance - 75.
The formula to compute the weighted mean should be
[tex]= \frac{15\times 85+ 15\times 90 + 30\times 80 + 10\times 95 + 5times 100 + 10\times 75}{15+15+5+10+30} \\\\= \frac{7225}{85}\\\\[/tex]
= 85
The sum of the weights should be 85.
Therefore we can conclude that the weighted mean should be 85.
