You have a homework grade of 55, four test grades that are 91, 82, 70, 68, and a final exam grade of 65. The table shows how these grades are weighted to calculate your course average.

Answer:

162.4

Step-by-step explanation:

To calculate your course average, you need to consider the weightage of each grade component. Based on the given table, the homework grade is weighted at 10%, the test grades are weighted at 40% altogether, and the final exam grade is weighted at 50%.

Let's calculate the weighted average step-by-step:

1. Calculate the weighted average of the homework grade:

- Multiply the homework grade (55) by its weight (10% or 0.1):

55 * 0.1 = 5.5

2. Calculate the weighted average of the test grades:

- Add up the test grades: 91 + 82 + 70 + 68 = 311

- Multiply the sum by the weight (40% or 0.4):

311 * 0.4 = 124.4

3. Calculate the weighted average of the final exam grade:

- Multiply the final exam grade (65) by its weight (50% or 0.5):

65 * 0.5 = 32.5

4. Add up the weighted averages from steps 1, 2, and 3:

5.5 + 124.4 + 32.5 = 162.4

5. Calculate the course average by dividing the sum by the total weight:

162.4 / 1 = 162.4

Therefore, your course average is 162.4.
