To calculate your final course average, we need to consider the weights assigned to each category of assignments.
1. Calculate the weighted average for each assignment category:
- Test grades: The test grades are major assignments, which account for 55% of the final course average. To calculate the weighted average, we sum up the test grades and divide by the number of tests. In this case, the sum of the test grades is 75 + 67 + 85 + 90 = 317. Dividing by 4 (since there are 4 test grades), we get 317 / 4 = 79.25 as the average for the test grades.
- Practice assignment grade: Practice assignments weigh 10% of the final course average. In this case, the practice assignment grade is 78.
- Quiz grade: Quizzes are minor assignments and account for 35% of the final course average. The quiz grade is 86.
2. Calculate the weighted average of the major and minor assignments:
- Multiply the weighted average of the test grades (79.25) by 55% (the weight of major assignments) to get the contribution of the test grades to the final course average: 79.25 * 0.55 = 43.5875.
- Multiply the quiz grade (86) by 35% (the weight of minor assignments) to get the contribution of the quiz grade to the final course average: 86 * 0.35 = 30.1.
- The contribution of the practice assignment grade (78) is 10% of the final course average: 78 * 0.1 = 7.8.
3. Calculate the final course average:
- Add up the contributions of each assignment category: 43.5875 + 30.1 + 7.8 = 81.4875.
Therefore, your final course average in Mr. Adeyemo's class at Westlake High School is approximately 81.49.
