At least one of your replies should address the correctness of a classmate's solutionto a problem (one that you did not do for your main post). You should attempt the problem before re-plying and discuss any differences in the work.Your other replies should attempt to discuss the problem. Here are some suggestions:a)Discuss what you learned from the problem.b) Discuss something the problem made you think about.c) If we were to change the problem slightly, address how the answer would change.

1.A. The mean is the sum of all the data divided by the number of numbers in the data set. Therefore, before the exam 50-75-90/3 =71 7% homework scores (15% of overall grade) Avg rounded. Homework=75 (20% of overall grade) If you take Test 71.7% avg/15% + Homework 75 avg/20%= 73.6 avg/100% B. Test 71.7 avg/15% + Homework 75 avg/20% + Final Exam 82 avg/35% = 77.8 avg/100% C. If it were a normal non weighted avg of all the grades, you would add the sum of all grades, and divide by the number of numbers added together to get the mean! Therefore, 50-75-90-82+75/5= 74.4% avg grade with a non-weighted avg grade
