In Marissa's calculus course attendance count for 15% of the grade quizzes count for 10% of the grade exams counts for 50% of the Grade and the final exam counts for 25% of the grade. Marissa have 100% average for attendance 93% for quizzes 86% for exams and 85% on the final. determining marissa scores average.
so just weight the scores, and you get
0.15*100 + 0.10*93 + 0.50*86 + 0.25*85 = 88.55
Well, let's crunch some numbers, shall we?
Since attendance counts for 15% of the grade, Marissa's attendance average score would be 100%.
Quizzes count for 10% of the grade, so Marissa's quiz average would contribute 9.3% (93% x 0.10) to her overall grade.
Exams, on the other hand, carry a weight of 50% in the final grade. This means Marissa's exam average would contribute 43% (86% x 0.50) to her overall grade.
Finally, the grand finale, the final exam! It counts for 25% of the grade, so Marissa's final exam average would contribute 21.25% (85% x 0.25) to her overall grade.
Now, let's add them all up:
Attendance: 15%
Quizzes: 9.3%
Exams: 43%
Final Exam: 21.25%
If we sum all these percentages together, we get Marissa's overall grade average. *Drum roll please*
The average score for Marissa's grades would be... approximately 88.55%!
Keep in mind that this calculation assumes the weighting percentages remain consistent throughout the course. Best of luck to Marissa!
To determine Marissa's score average, we need to calculate the weighted average of each component of her grade.
Let's assign the following weights to each component:
- Attendance: 15%
- Quizzes: 10%
- Exams: 50%
- Final Exam: 25%
First, calculate the weighted average for each component:
Attendance component:
Average score: 100%
Weight: 15%
Weighted score = Average score * Weight = 100% * 15% = 15%
Quizzes component:
Average score: 93%
Weight: 10%
Weighted score = Average score * Weight = 93% * 10% = 9.3%
Exams component:
Average score: 86%
Weight: 50%
Weighted score = Average score * Weight = 86% * 50% = 43%
Final Exam component:
Average score: 85%
Weight: 25%
Weighted score = Average score * Weight = 85% * 25% = 21.25%
Now, we can calculate the overall weighted average:
Total weighted score = Weighted score of Attendance + Weighted score of Quizzes + Weighted score of Exams + Weighted score of Final Exam
= 15% + 9.3% + 43% + 21.25%
Therefore, Marissa's overall score average is 15% + 9.3% + 43% + 21.25% = 88.55%.
To determine Marissa's score average, we need to calculate the weighted average of each category based on their corresponding percentages.
1. First, let's calculate the weighted average for attendance:
Since the attendance count is 15% of the grade, we multiply Marissa's 100% average attendance score by 0.15:
Attendance weight = 100% x 0.15 = 15
2. Next, let's calculate the weighted average for quizzes:
Quizzes count for 10% of the grade, so we multiply Marissa's 93% average quiz score by 0.10:
Quiz weight = 93% x 0.10 = 9.3
3. Now, let's calculate the weighted average for exams:
Exams count for 50% of the grade, so we multiply Marissa's 86% average exam score by 0.50:
Exam weight = 86% x 0.50 = 43
4. Finally, let's calculate the weighted average for the final exam:
The final exam counts for 25% of the grade, so we multiply Marissa's 85% final exam score by 0.25:
Final exam weight = 85% x 0.25 = 21.25
To find the overall score average, we add up the weighted averages from each category:
Overall average = Attendance weight + Quiz weight + Exam weight + Final exam weight
Overall average = 15 + 9.3 + 43 + 21.25
Overall average = 88.55
Therefore, Marissa's score average is 88.55%.
