I wasn't sure what section to put this in....
Can someone tell me what I have to make on my final to get an A?
Attendance 5% = 95
Case Studies (3) 20% = 100, 95, 95
Exams (3) 75% = 86, 80 (the final is the last exam so it's 25%
so for attendance, you got 95% of the possible attainable points, so you have:
0.95 * 5 = 4.75% from this section
for case studies, you have, (100 + 95 + 95)/300 * 100 = 96.67 % of the possible points, so you have:
0.9667 * 20 = 19.33 % from this section
so now you have: 4.75 + 19.33 = 24.08 % so you need an additional 65.92% to get an A.
so we want [(86 + 80 + x)/300]*75 = 65.92
=> [(86 + 80 + x)/300] = 65.92/75 = 0.8789
=> 86 + 80 + x = 300*0.8789 = 263.67
=> x = 263.67 - 86 - 80 = 97.67
yup, those 80-something percents are going to cost you. you need a 97.67, let's say 98% on the final to get an A
Average: 296/300 = .986663 Given Tests:
1st Test:100%
2nd Test:100%
3rd Test:96%
Of total: .98666*.6 = .592 = 59.2%
Of total: 1*.05 = 5%3 Given Calculator Labs:
1st Lab:100%
2nd Lab:100%
3rd Lab:100%
Of total: 1*.15 = 15%Webworks Grades
Scored 100% on every one!
Total: 15% + 5% + 59.2% = 79.2%Final Grade that would keep me from getting an A:?
To get an A, you need another 10.8%. Out of the 20% possible on the Final, you need only 10.8/20 = .54 = 54% on the Exam. Anything less and you get a B!
