What dyhu mean? At a level? Gcse?
At a level a high B is 78%
and an A is 80%
but this depends on the year and the paper
(8 x 80) - (7 x 78) ie 640 - 546 = 94. Not particularly likely?
78 rounded to the nearest ten is 80
80
2 + 78 = 80
78 + 79 + 80 + 80 + 81 + 81 = 479
To get a final grade of 72, you need a 72 on the exam. For a final grade of 75, you need an 72 on the exam. For a final grade of 80, you need a 99 on the exam. If you get 100 on the exam, your final grade will be a little over 80.
80%
Assuming the 78 is 80% of the class and a 60 is passing: 78*.80 + x*.20 = 60 .2x + 62.4 = 60 .2x = -2.4 x = -12 So you cannot really fail the class. (If you need a 70 to pass the class you need at least a 38.)
78% of 80 people= 78% * 80= 0.78 * 80= 62.4 people
you would need a 94. Multiply your current average of 78 times 7 to get to 546. To have an average of 80, you multiply 80 *8 to get 640. 8 represents the total number of exams you have taken. I am assuming the question is "what does the student need to score on his eighth exam to get an 80 for the semester?" subtract 546 from 640 and you get 94.
78% is considered a C. Normally the letter grade scale is that an A is 90-100, B is 80-89, C a 70-79, D is 60-69 and F is anything below 60.
(75+83+78+X)/4=80, solve for X X=4*80-75-83-78 So X=84
Either 80% or 85% but aim for 100% when your taking the test!
80 is 2 bigger than 78
As a percentage it is 72%
(8 x 80) - (7 x 78) ie 640 - 546 = 94. Not particularly likely?
