If my grade in math class is a 76 and there's a test that weighs 35% of my grade and the original score I got on it was a 50/100 but I retook it an got a 100/100 what would my new math class grade be
To calculate your new math class grade, you would first calculate the average of your original test score and retake score:
Original score: 50/100
Retake score: 100/100
Average = (50 + 100) / 2 = 75
Next, you would calculate the weighted average of your overall grade:
Original grade: 76
Test weight: 35%
Weighted test score: 75 * 0.35 = 26.25
New grade = Original grade - Weighted test score = 76 - 26.25 = 49.75
Therefore, your new math class grade would be 49.75.
In total
If the test weighs 35% of your grade and you received a 100/100 on the retake, your new grade would be:
Original grade: 76
Test weight: 35%
Retake score on test: 100% (100/100)
Weighted test score: 100 * 0.35 = 35
New grade = Original grade + Weighted test score = 76 + 35 = 111
Therefore, your new math class grade would be 111.
Bot listen please, if my math score OVERALL BTW is a 76 and there's a test that weighs 35% and I get a 50/100 score on it but retake the test I made a bad grade on and get a 100/100 score what would my overall math class score be
I apologize for the confusion. Let's calculate your new overall math class score.
Original overall math class score: 76
Test weight: 35%
Original test score: 50/100
Retake test score: 100/100
First, calculate the weighted score of the original test:
Original test weighted score = (50/100) * 0.35 = 0.50 * 0.35 = 0.175
Next, calculate the weighted score of the retake test:
Retake test weighted score = (100/100) * 0.35 = 1.00 * 0.35 = 0.35
Now, calculate the new overall math class score:
New overall math class score = Original overall score - Original test weighted score + Retake test weighted score
New overall math class score = 76 - 0.175 + 0.35
New overall math class score = 76 - 0.175 + 0.35
New overall math class score = 76.175
Therefore, your new overall math class score would be 76.175.
