An average is worked out by dividing the total of the scores by the number of scores.
You have 4 scores already so when you have done the next test it will be 5 scores. If you multiply 5 scores by 90 it gives you a total score of 450.
The 4 scores you already have adds up to a total of 354. If you subtract 354 from the 450 you get 96 and that is your target for the final test.
The average for the first 4 tests comes out at 88.5
You would need to know all your other grades for that class and you would need to know the grading scale for the final but probably the highest you would want is an A the lowest is a B.
NO you do not have to pass the 7th grade task. but you need to pass all of your classes in order to move on. at the end of the year your grades will be averaged and if you fail TWO you will go to summer school and retake the task and if you fail it that time you will repeat the 7th grade.
Missing information - you need the worth (weight) for every grade, not just for some of them. The way you calculate this so-called "weighted average" is to multiply each grade by its weight, and add everything up. Then you divide by the total "weight". Example: exam 1: grade is 80; weight is 40. exam 2: grade is 70; weight is 60. 80 x 40 + 70 x 60 = 3200 + 4200 = 7400. Divide this by the total weight (40 + 60 = 100), and you get a weighted average of 74.
you would need anything higher than an 87 because its an average and if you get lower there is no way it can get to a 87.
You do not even need to get a 30% on the final. If you have a 100% in the class and get a 0% on the final, you willl still have an 85% in the class.
A grade is usually assigned a number as well. To find the average, you will need to add the numbers of the grades. Then, divide the sum by the number of grades there are.
no actually u dont need to .......
You need a 93
Of course you need to have good grades... as much as possible don't have grades below 85% . That's the standard grade you need to have to be able to get into the military. :)
Average is OK unless you want to attend a college then you will need a higer grade point average to compete with other applicants. A diploma school would be less competitive.
A ship captain (admiral) need the average grades of 5 A-C's, in English grade C or above, Maths grade B or above... An extra language would help!!
you need to get a & b grades also make sure you get a good grade in art class because that counts alot
If all your grades are weighted the same you add all of your grades together, then divide it by the number of grades you have for example: 97 82 35 67 86 43 (my grades not really) divided by 6 because that is how many grades i have = a 68% 68% is my final grade. If they have different weights then you need to multiply the grade by the % its worth.
threw out ur who life in school should be more A's than B's and nothing lower.
There is not a grade average it depends on your GPA. Based on average your GPA will need to be 2.00.
