    How do you do standard deviation on a Casio fx115ES???? Help!

  • portroyal Dec 19, 2008

    re: single variable statistics - if I simply enter three data points (5,10,15) in 'data' and then enter 'var' to see 'n', x-bar, etc., I get nothing back - it doesn't seem to have 'read' my data or done any calculation. Is there some other procedure you have to go through so the calculator knows your through entering data then 'crunch' the numbers?

take you sales for the last year and put it into a calculator, then press plus + and then 6 and then the per cent key %

Take your sales from last year, multiply by 6 and then divide by 100. That is the amount you will increase. Add it to last years sales.

Only thing is I did not find windows 8 drivers for this printer as standard so you may run into trouble with computers running windows 8 as each computer has to have the exact operating system printer driver designed for its exact operating system .
Unless you can find windows 8 drivers somewhere on the internet

What are rational numbers


Use the words: decimal part, not decimal fractin
Any number whose decimal part is periodic (has a recurring pattern that repeats indefinitely) is equivalent to a rational number, IS a rational number
0.345 345 345 ... =345/999=115/333
In the following screen captures, discard the last digit if it does not belong to a period. It is the effect of rounding up of the calculator


3deb58af-3d70-4f55-adc1-35b7c9392031.jpg
Period is 345

7b3e81fc-c59c-455d-a5f2-e4b169925684.jpg
Period is 1
847342a7-5d3b-4604-b706-2ec9853c2dc7.jpg
Period is 09
8f929e6d-512c-41e2-a253-ffa88c0ab74e.jpg
Period is 79
0417fef1-6661-4f31-868f-8202884893ae.jpg

In general, if you have a decimal part of the form 0.d_1 d_2 d_3....d_n d_1 d_2 d_3 ...d_n ... where d_1 is the first digit of the period, d_2 is the 2nd digit of the period, ..., d_n is the n-th digit (and the last one) of the period, then the fraction representation of
0.d_1d_2...d_n d_1d_2... d_n ...=(d_1d_2...d_n)/(99...9) where the number of 9's in the denominator is equal to the number of digits in the period.
Once the fraction is found, one should reduce it to its simplest form.

I am horrible at maths need help asap


With algebra you are learning problem solving-that is the process of problem solving using rules and equations. The best way to learn it is to shut out all distraction and work at it. If there is something you don't understand you may have to go back to the beginning and learn all the principals and rules that you don't understand- Algebra can be a very hard subject but it can be concord with persistence.
