Reverse percentage |
2006-04-19 |
|
From Mike:
How would I calculate a reverse percentage?
Let me give you an example. I have two values that calculate to a success rate of 93.32. Total=1546051 Failures=103302. (1546051-103302)/1546051=93.32% success.
Now how much would I need to increase the total value to get the success up to 95%?

Finding a rule for a sequence |
1999-02-17 |
|
From Lindsey Masters:
I'm doing a maths investigation and i have a sequence which goes:- 13,16,25,32,45,56,73. Our teacher told us we have to find a rule by looking at the differences of the terms until we find a constant. The first differences are:- 3,9,7,13,11,17. The differences of these are:- ...... Please could you tell me how to work it out so that I could work out the rules of similar sequences.
