What number it is the ones is greater than tens and the tens digits is 80 what am i?
You are someone who asks arithmetical questions!
The number you are looking for is 89.
What is the mean and median and mode of 22 36 9 27 3020?
The mean of the set of values is the average of all these values. Add up all the values and divide the sum by 5 to get:
(22 + 36 + 9 + 27 + 3020)/5 = 622.8
The mode is the number that occurs the most. There is no mode here since each term occurs once, but you can't have two modes occuring at the same number of times!
The median is found via determining the center of the set of the values in ascending order. Rearrange the values in that order to get:
9 , 22 , 27 , 36 , 3020
Then, the median is 27.
Does variance provide more information than standard deviation?
No. Because standard deviation is simply the square root of the variance, their information content is exactly the same.
What are the meaning and examples of decimal and fraction?
a decimal is a proper fraction whose denonimater is a power of ten.
a fraction is the quotient of two rational numbers.

Does studying Range median mode or mean help later in life?
Anything you learn tomorrow will be based upon something you learned today, and the stuff you learn today will be based upon the stuff you learned yesterday. There's really no way of predicting what information you will be required to learn in the future, so you better learn as much as you can today. Your first job or your next job may require you to know something about -- or to learn about -- statistics. Perhaps you will work for a political polling company, such as Rasmussen or Zogby, or a testing company, such as ETS. Or maybe you'll work for an engineering firm and be required to do a statistical analysis that requires an understanding of probability and statistics. Or maybe, you'll simply find yourself in a conversation at a highbrow party or a business function, where a basic understanding of math, including the parameters you mentioned, will be key to your understanding of what's being discussed. Maybe a politician who is running for office will cite data to impress you, but if you don't understand the rudiments of stats, you won't be able to tell whether he's telling the truth or is full of crap.
How many ways could you get a sum of 3 when two dice are thrown?
Two ways- one on the first die, and two on the second die, and visa versa.
What were Electronic Data Systems stock values in 1988 and 1990?
I am looking for the share prices for Electronic Data Syaytems in the years 1990 and 1988.
How do you work out an average?
add all the numbers together and then you divide it by the number of numbers there are for example if you have 20, 10, and 30 they equal 60 and since there are 3 numbers you divde 60 by 3 and there you go you get 20
Can you make a 4banger in to a v6 in an Alero and what all would it take?
Change engines. It would take a donor car and lots of work by someone who knew what they were doing. Forget going that route. Sell the 4 cylinder and buy a V6 if that is what you want.
What are the measurements that fall beyond three standard deviations from the mean?
They are observations with a low likelihood of occurrence. They may be called outliers but there is no agreed definition for outliers.
What is the calulated value of the standard deviation of returns for -22.0 -2.0 20.0 35.0 and 50.0?
It is 28.73
Vasilka is one of the similar woman names like Vasilissa and Vasiliki. I think that Vasilka is mostly used in Bulgaria but also in other Balkan countries, and Vasilissa mostly in Russia. Vasiliki is the Greek name. All of them mean ''the royal one'' or ''the Queen'' and the name comes from the Greek word ''Βασιλεύς'' (pronounced Vasilefs) or ''Βασιλιάς'' (pronounced Vasilias). The same name for the men is ''Vasilis''.
If the true value is 21.751 grams what is the absolute error and the percent error?
In order to determine the absolute error of this you would have to have a measurement or an estimate of whatever this object is. at which point you would take the difference between the two.
For example: 21.571 is the True value 20.000 is the Recorded Value.
Thus: (True value) - (Recorded Value) = Absolute error (21.571) - (20.000) = 1.571
To determine the Percent value, applying the skills learned above, it is represented by the following equation
(Recorded value - True value) / True value*100%
(20.000 - 21.571) / 21.751*100% = -7.28%
It is possible to have multiple points of absolute error for instance. If you have 3 measurements one above the true value, the true value, and one below the true value. (e.g 20, 21.571, 22.571) can be represented as +/- 1.571g
How can you find the total number of 4-number combinations possible from digits 1-7?
*inclusive: 74 = 2401 *exclusive: 7*6*5*4 = 840
What is the probabiltiy of landing on a number with 3 factors on a spinner with 8 possible outcomes?
The answer will depend on what the 8 numbers on the spinner are!
The mathematical probability of getting heads is 0.5. 70 heads out of 100 tosses represents a probability of 0.7 which is 40% larger.
