Say the score is 8/12 you divide 8 by 12 then multiply that number by 100. You'll need a calculator! :P
Zinc: 47,98 % Chlorine: 52,02 % The chemical formula is ZnCl2.
If you mean potassium Cyanide, the formula is KCN
Do you mean the molecular formula? If so, then it is C4H10. If you mean empirical formula, then it is C2H5.

Carbon
the total grades of the student in a particular subject area divided by the total number of students multiplied by 100
The term "mean" is another way of saying "average." In order to calculate a mean percentage score, you must add together all the percentages, and divide the total by the amount of percentage scores being used.
z=x-mean / sd
Set up a formula that divides their actual score by the maximum score available. Then format that result as a percentage. So say they had a maximum score of 60 and they scored 45. If the 45 is in cell B3 you could put a formula in cell C3 as follows: =B3/60 In this case it would give you 0.75 which if formatted as a percentage will give you 75%. So put all the scores of students in one column and in the first cell of the column beside it, put the formula that divides their score by the maximum. Copy the formula down for all others and format them as a percentage.
you do your score, divide it by the 100% mark and then times by 100 eg: 32/35 I would do 32 divided by 35 and times by 100 to get the overall percentage
Add up all the percentages and divide by the total number of them, gives you the average mean.
100 x (standard deviation/mean)
The formula of percentage is pi. This is used in math.
Depends. The percentage,of credit used to the percentage not used is more important. Let's say you are using 71% of your available credit your score will be lower. The income ratio to debt is also used.
1% increase
The z-score can't be calculated with the information given. A mean & standard deviation is required to put into the formula: Z = (x-mean)/sigma. Your x value is 10.
There are two formulas used in getting the simple percentage in statistical treatment in research. The first formula, Frequency and percentage distribution, % = f/N x 100, where f is the frequency and N is the number of cases. The next formula is Mean where the mean equals the sum of all scores divided by the number of cases.
