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
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).
How do you find the sum of the squares of consecutive even numbers?
What I would do is square each of the consecutive even numbers, and then add their squares. It depends on how complex you want the answer to be. If you need a formula to do it, then use the following. If it's always starting at two, then use the formula: Sum of even numbers' squares from 0 to w. x=w/2 f(x) = (4*x^3+6*x^2+2*x)/3 If you put in 1, then you get the first even number squared. If you put in two, then you get the sum of the squares of the first two even numbers. Three will give you the sum of the squares of the first three even numbers. If you need to vary where it starts (e.g. adding the squares of the even numbers from 8 to 26) the use that formula with the larger number (13, because 26 is the thirteenth even number) and then subtract the formula at the lower number minus one (3, since 8 is the fourth even number, and 4-1=3). F(13)=3276; F(3)=56; 3276-56=3220. So, the sum of the squares of the even numbers from 8 to 26 is 3220. Sum of even numbers' squares from w to z. x=(w/2)-1 y=z/2 f(y)-f(x)
Two numbers have a sum of 20 if their squares is a minimum find the numbers Complete the square to find the minimum?

How do you factor 121a2 plus 144b2?
There is a formula for the difference of two squares. The sum of two squares doesn't factor.
What is the sum of a quadrilaterial?
The formula for quadrilaterals depends on what shape. Example.... Formula for rectangles: 2L x 2W Formula for squares: 4S
Sum of squares of odd integers?
The formula for the sum of the squares of odd integers from 1 to n is n(n + 1)(n + 2) ÷ 6. EXAMPLE : Sum of odd integer squares from 1 to 15 = 15 x 16 x 17 ÷ 6 = 680
What is the formula for the how many squares do you see puzzles?
Sum of N2 for N=1 to X, and X is the number of squares across the top or side on the large square.
What is the formula for solving single factor ANOVA?
There is no single formula.It is necessary to calculate the total sum of squares and the regression sum of squares. These are used to calculate the residual sum of squares. The next step is to use the appropriate degrees of freedom to calculate the mean regression sum of squares and the mean residual sum of squares.The ratio of these two is distributed as Fisher's F statistics with the degrees of freedom which were used to obtain the average sums of squares. The ratio is compared with published values of the F-statistic since there is no simple analytical form for the integral.

What formula of triangles says that the square of the hypotenuse id equal to the sum of the squares of the other two sides?
pythagorean theorem
Whose formula for triangles says that the square of the hypotenuse is equal to the sum of the squares of the other two sides?
Pythagoras' theorem
Why is the residual sum of squares bigger then total sum of squares when there isn't a constant?
There is a calculation error.
What is the pythagorean theorem not just the formula?
The square on the hypotenuse of a right-angled triangle is equivalent to the sum of the squares on the two adjacent sides.
