hey ppl. i got a 68% on my math final and it was worth 5% and I have a 72 in the class so what was my final gr

Answer 1

Your math final is worth 5% of the total 100% of your final mark
Your class mark is worth 95% of the total 100% of your final mark

Thus,
5% of 68% is = 0.05*68 = 3.4%
95% of 72% is = 0.95*72 = 68.4%

Adding those together gives you 68.4+3.4 = 71.8% final mark, which is basically your final class mark

Answer 2

69.444444444444= 69

Answer 3

final grade will be 0.95*0.72 + 0.05*0.68 = 71.8%
