This is a bit of a trick question.
12 = 16 - 4
162 + (-4)2 = 256 + 16 = 272
split 10 in two parts such that sum of their squares is 52. answer in full formula
The sum of their squares is 10.
If the regression sum of squares is the explained sum of squares. That is, the sum of squares generated by the regression line. Then you would want the regression sum of squares to be as big as possible since, then the regression line would explain the dispersion of the data well. Alternatively, use the R^2 ratio, which is the ratio of the explained sum of squares to the total sum of squares. (which ranges from 0 to 1) and hence a large number (0.9) would be preferred to (0.2).
There is a calculation error.
272
If there's some other meaning that is separate from maths, then I don't know it, but the maths answers is; if you add each digit of a number together (in 125 you would do 1+2+5)then you have the sum of its parts
8081 can be the sum of two perfect squares because its perfect squares are 41 x41+80x80=1681+6400. Answer=1681+6400
Sum of squares? Product?
-16 and +17
The sum of the squares of the first 20 natural numbers 1 to 20 is 2,870.
There are several parallelogram depending on the context. One such is that the sum of the squares on the four sides of a parallelogram equals the sum of squares on its diagonals.
It is Fermat's theorem on the sum of two squares. An odd prime p can be expressed as a sum of two different squares if and only if p = 1 mod(4)
