If someone has a 73% and they get a 50 on a test what is their new grade and the weight of the test is 26
To calculate the new grade, you need to consider the weight of the test.
Let's assume the weight of the test is out of 100, meaning it contributes 26% to the overall grade.
First, you need to find out how much the test is worth in terms of percentage. You can do this by multiplying the test score (50) by the weight of the test (26%) and dividing it by 100.
(50 * 26) / 100 = 13
Next, find out what percentage is left after excluding the weight of the test from the overall grade. Subtract the value calculated above (13) from the original grade (73).
73 - 13 = 60
The new grade would be 60%.
To calculate the new grade after adding the test score, you can use the weighted average formula.
Weighted Average = (Old Grade * Weight of old grade + Test Score * Weight of test score) / (Weight of old grade + Weight of test score)
In this case, the old grade is 73%, the test score is 50, and the weight of the test is 26%.
Weighted Average = (73% * 100 + 50 * 26) / (100 + 26)
Weighted Average = (7300 + 1300) / 126
Weighted Average = 8600 / 126
Weighted Average = 68.25
Therefore, after adding the test score of 50, the new grade would be approximately 68.25%.
