Add them together. Divide that total by 10.
A ten-figure number would be any number that has ten digits: 1,234,567,891 -- it can be any numbers, as long as there are ten single numbers put together.
38.5
Just add them together, and divide the result by 10. (For the average of a larger set of consecutive odd numbers, it's faster to use the formula for an arithmetic series to add them up. Also, the average of such a set is the same as if you just average the first and the last number.)
The average of the first ten prime numbers is 12.9.
A ten sided figure is a decahedron.
A plane figure bounded by some numbers of straight sides is called a polygon. Thus a polygon with ten-sided is called a decagon.
The mean is the sum of all of the numbers in the series divided by the number of items in the series. In this case it is the SUM(10...190), which equals 1900. There are 19 items in the series, so the mean is 1900/19 = 100.
-- Write down a list of the first ten whole numbers. -- For each one, multiply it by itself, and write the product next to it.
A decaredra is the ten face solid figure.
They are: 2 3 5 7 11 13 17 19 23 and 29
Add all of them, and divide by the amount of numbers. Get your answer. It is.. 12+10+9+15+16+10=72. 72/6=12 Your answer is twelve.
There are ten numbers from one to ten, if you include the one, and the ten. If you leave the one and ten out, then there are only eight numbers.
