Your grade in the class consists of 2 midterms 15% each, homework 10%,
projects 5%, attendance 10%, and final 30%. Find the weighted mean if your
scores are as follows in the class.
Midterm 1:85
Midterm 2:90
Final : 80
Homework: 95
Project : 100
Attendace : 75
What is the sum of the weights that is find w =?

Answer :

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.
