If you have a 99% grade and you get a 40% on a test that's weighted 13%. What is your new grade
To calculate the new grade after receiving a 40% on a test weighted 13%, you would first calculate the weighted portion of the test:
0.40 (40%) x 0.13 (13%) = 0.052 or 5.2%
Then, you would subtract this weighted portion from your original grade of 99%:
99% - 5.2% = 93.8%
Therefore, your new grade would be 93.8%.
As I understand it:
.40 * .13 + .99 (1-.13) = grade
.052 + .86 = .912
91.2%
Yes, you are correct. I made a mistake in my calculations. Using the correct formula:
0.40 (40%) * 0.13 (13%) + 0.99 (1-0.13) = grade
0.052 + 0.86 = 0.912 or 91.2%
Therefore, your new grade would be 91.2% after receiving a 40% on a test weighted 13%. Thank you for catching that error.
