Solve clustering problem. After step 1 i.e putting each data-point to a cluster now I want to calculate the mean or average of all of the data-points in a specific cluster. let suppose we have some data-points like A(2,3), B(4,5), C(6,7), D(8,9) in a cluster. How can I calculate their average?

Note that ( x + y ) 3 = x 3 + y 3 + 3 x y ( x + y ) .. If n or n + 1 is the cube of an integer, the result is clear by the uniqueness of prime factorization, so we assume that neither is the cube of an integer. Then neither is n ( n + 1 ). Set x = n 1 3 and y = ( n + 1 ) 1 3 .. If x + y is rational, then so are ( x + y ) 3 and 3 x y ( x + y ). Hence 3 x y is rational. Thus 27 n ( n + 1 ) must be the cube of an integer, a contradiction.

Is a weighted average, assuming the weights sum up to one, always smaller than the unweighted arithmetic average? As if the weights are smaller than one the weighted mean is a convex combination of the individual points. Is there any condition on the individual observation for the statement to hold true?

Сalculate a windowed average where the newest value replaces the oldest value in a set of size 10. In this case, I have a real-time number stream and have access to current value, current average and the previous value.Is there any way to calculate this value incrementally storing minimal amount of historical state?

Calculate an average or typical time. If I would just use the median (or other "normal" types of calculating an average), for example 23 : 59 and 00 : 01 would yield 12 : 00 when it should 00 : 00. Is there a better method?
