How do I figure a mean?

Add the numbers together, then divide by the number of numbers.

For example, to figure the mean of 3, 4, and 5, add 3, 4, and 5 to get 12. Divide by the 3 and get 4. Thus the mean of 3, 4, and 5 is 4.

How to calculate mean

The mean is (1+5+9)/3 = 5.
The squared deviations are (1-5)^2=16, (5-5)^2=0, and (9-5)^2=16.
The sum of the squared deviations are 16+16 = 32.
Divided by one less than the number of data points, 32/(3-1) = 16.
The square root of 16 is 4. This is the sample standard deviation.

How to calculate 5^(-1)mod 792

I am sorry, but I was under the impression that the modulo operation involves integer divisions only. This means it involves only integers. However 5^(-1) is a rational number that is not an integer. And then I could be wrong.
As to doing modulo operations with this calculator, well you can't. Sorry again.

How to I stop my sharp EL-531X calculator from rounding when converting from decimal to scientific notation?

You need to select the number of decimal places you would like, or if you would like the calculator to behave as normal. Press SET UP and select FSE (press 1) . You now have 5 options.
0: FIX means you can choose a fixed number of decimal places for every calculation.
1: SCI means scientific notation and choose the number of significant values you would like to deal with.
2: ENG means engineering and the power goes up in multiples of 3.
3: NORM1 and 4: NORM2 are the usual or normal settings on the calculator. Most school calculations will use NORM1 mode.

First thing to do, before you enter the value of the equation to your calculator multiply the first term((1/3x+5) from the second term(1/3x+5) to make your answer simplified.Then after that you will observed that your answer look like in this pattern AX2 +BX+C it means that the equation is in general form of quadratic equation. So, in your problem,we are looking for a value of X1 and X2,when you used your calculator in solving this problem, First On you calculator then look for the mode then press it after that look for the equation(EQN).Then from the side of the word EQN there is a corresponding number to press,from my calculator it is number 5..Then press it.After you press it, there is a equations choices,look for the equation AX2 +BX+C then press it(given number to press). Now,enter the value of A, B and C from your simplified answer. After pressing the value of A press = sign from your calculator same as B and C.After you enter all the value of A,B and C continuously press = sign from your calculator till you get the answer, the value of X1 and X2.

Random number generators on computers are not really random. They need to be "seeded". If you seed the random number generator with the same seed each time you will generate the same list of numbers. A common technique in computer programming is to seed the random number generator with a value like the number of seconds that has occurred since midnight. This gives you the illusion of real random numbers.

Look up the word "Seed" in your calculator documentation and it will most likely tell you how this is accomplished on the TI calculators.
