Help figuring out my grade!?

Question

I need to figure out what grade I have right now and what grade I need to get on my final to get an A in the class...

The breakdown is like this
15 % Class Attendance and participation in discussions
20 % Midterm Examination
40 % Writing Assignments
25 % Final Examination

Ive gotten 100% on attendance
I got an 86% on my midterm
and I got an 94% on my writing assignments.

Please help!! Thanks so much!!

Answer 1

So far you have a 93.

I don't know what grade you need for an A, but if you need a 90 overall for an A, then you need to get an 81 on your final.

But if you need a 94 for an A, then you need to get 97 on your final.

Answer 2

100 + 86 + 94 = 280
280 divided by 300 = 0.93...
right now you have a 93%, you will need at least a 100% to get a final grade of 95% if you get an 83% you will still have a low A-.

Answer 3

15% of 100=15
20% of 86=17.2
40% of 94=37.6
so so far 69.8 out of 75
whateveryou get in the final exam find 1/4 th of that and add to
69.8 toget your grade

Answer 4

because of your attendence you got a full 15%

and you got a 17.2% on your midterm examination

for you writing assignments you got an 37.6%

ok this is your grade for each test score:

grade on test your grade
100% 94.8%
98% 94.3%
96% 93.8%
94% 93.3%
92% 92.8%
90% 92.3%
88% 91.8%
86% 91.3%
84% 90.8%
82% 90.3%
80% 89.8%
78% 88.3%
76% 87.8%
74% 87.3%
72% 86.8%
70% 86.3%

ok i'm thinking you kinnda get the pattern now.
good luck on your test!

Answer 5

100%=1, 86%=0.86, 94%=0.94. Same with the percentages.
So...
0.15(1)+0.2(0.86)+0.4(0.94)
=0.15+0.172+0.376
=.698
.698/.75=.9300... ----> You have a 93% right now.
Assuming you need a 94 to get an A...
.698+0.25(x)=0.94
0.25x=0.242
x=0.968 ----------------> You need a 97% to get an A.

Answer 6

A I will consider is between 85 to 89.9:

a15 + b20 +c40 +x=what grade intended(F)

a=decimal (percentage) coefficent of Class Attendance

b=decimal (percentage) coefficent of Midterm examinations

c=decimal (percentage) coefficent of Writing Assignments

x=decimal (percentage) coefficent of Final Examination

F=grade overall intended(whole percentage)
-------------------------------------------------- we want to solve for d
a=1, b=0.86, c=0.94, x=(whole percentage)mark on final, f=first 85, then 89.9
