How many five digit numbers can be obtained given that that the ten thousands place cannot be zero?
9*10*10*10*10 or 90000
How do you find the mode for these numbers 2 3 4 5 6 6 9?
All you have to do is find the number that appears the most. The mode for 2 3 4 6 6 and 9 would be six because there are two sixes. There is only one 2 3 4 5 and 9.
If you had the numbers 2 4 4 6 6 6 8, the mode would be 6. There are three sixes and only two fours. The same goes for any set of numbers.
If there are three fours and three sixes, there would be two modes-4 and 6.
Hope this helped!
What is 7896 to the nearest 10?
7900.
Since the 6 is greater than 5, you round up, but since you have a 90, you have to round that up, too.
It goes:
7896 rounds up
7899 round up
7900
I hope that helps.
What are odds of rolling six of a kind with six of a kind on one roll?
If you have 6 dice and you roll them one at a time (to explain this more easily but it works if you roll them simultaneously).
It doesn't matter what your first number is, so the odds of you getting that number is 1/1.
The second roll you have a 1/6 chance of getting the same number and this will be the same for the third, fourth, fifth and sixth dice.
Thus, you multiply each of these odds out.
1 x 1/6 x 1/6 x 1/6 x 1/6 x 1/6
Which equals a 1/7776 chance of rolling six of a kind in any one go.
If you have already rolled a six of a kind, it will still be a 1/7666 chance of getting it again because your previous actions do nothing to influence the chances of your future actions.
If you are wondering what the chances of rolling two 6 of a kinds over 2 goes you have to multiply the chances of getting a 6 of a kind by the number of times you want to get them (so (1/7776)2) which equals 1/60466176.
The formula used for working this out is (1/Ns)Nd-1
Where Ns is the number of sides on each die and Nd is the number of dice. It is minus 1 because it doesn't matter what is thrown on the first roll. If it matters what you roll (e.g. you have to throw a six every time), then on your first roll you have a 1/6 chance of rolling that number and so the -1 is not necessary in the formula.
What is determination of sample size?
It is the process of deciding how large a sample is required so that the variable(s) of interest can be estimated to the desired degree of accuracy.

The variance ratio test is a statistical method used to assess the presence of a unit root in a time series, which indicates whether the series is non-stationary. Developed by Lo and MacKinlay, it compares the variances of different time intervals of the series to determine if the observed variance is consistent with a random walk model. A significant difference in variances suggests that the series may not be stationary, implying that past values have a persistent effect on future values. This test is commonly used in finance and econometrics to analyze asset prices and economic indicators.
This is a factorial problem. The first number can be any of ten digits, the second any of nine (because you can't repeat a digit), the third any of eight and the fourth any of the remaining 7 digits. 10x9x8x7=5040 combinations.
Infinite. If numbers can be repeated, the list could go on nonstop.

Difference between declaring a variable and definition a variable?
Declaration is a promise: 'I will define (or has defined) this variable/function somewhere else'.
