Why is the residual sum of squares bigger then total sum of squares when there isn't a constant?
There is a calculation error.
Can 8081 be the sum of two perfect squares?
8081 can be the sum of two perfect squares because its perfect squares are 41 x41+80x80=1681+6400. Answer=1681+6400
How do you find the are of a figure?
You count the inside squares of the figure.
What is the sum of the squares of the first 20 natural number1 to 20?
The sum of the squares of the first 20 natural numbers 1 to 20 is 2,870.
What is the rule which tests whether a prime number can be written as the sum of two different squares?
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)
The sum of two positive numbers is 4 and the sum fo their cubes is 28 What is the sum of their squares?
The sum of their squares is 10.
If the regression sum of squares is large relative to the error sum of squares is the regression equation useful for making predictions?
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).
Why is the residual sum of squares bigger then total sum of squares when there isn't a constant?
There is a calculation error.
How do you figure area when all 4 sides are different?
You need to cut up your figure into several parts in shapes for which we know how to calculate areas, such as squares, rectangles, and triangles. The area of your figure is the sum of the areas of its parts.
Explain the square of the sum of two numbers is different from the sum of the squares of two numbers?
split 10 in two parts such that sum of their squares is 52. answer in full formula
Can 8081 be the sum of two perfect squares?

Sum of squares? Product?
How do you find the are of a figure?
You count the inside squares of the figure.
What is parrallelogram law?
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.
What is the sum of the squares of the first 20 natural number1 to 20?
The sum of the squares of the first 20 natural numbers 1 to 20 is 2,870.
