Answer 1

Makori's final mark is 77.4%.

Step-by-step explanation:

To determine Makori's final mark, we need to calculate the weighted average of his marks for each term and the final examination. Term 1 is worth 40% of the final mark, term 2 is worth 40%, and the final exam is worth 20%. Here's the step-by-step calculation:

1. Convert the percentage scores to decimal form: Term 1 = 0.86, Term 2 = 0.75, Final exam = 0.65.
2. Multiply each score by its respective weight: Term 1 = 0.86 x 0.40 = 0.344, Term 2 = 0.75 x 0.40 = 0.300, Final exam = 0.65 x 0.20 = 0.130.
3. Add up the weighted scores: 0.344 + 0.300 + 0.130 = 0.774.
4. Convert the weighted score to a percentage: 0.774 x 100 = 77.4%.

Therefore, Makori's final mark is 77.4%.
