Counter example that a positive integer is not equal to the sum of two squares?
3 is the smallest integer that cannot be written as the sum of two squares. This is easy to see, since the only squares less than or equal to 3 are 0 and 1.
How do you solve the sum of squares?
If a question says solve the sum of the squares of 3 and 10, you would multiply 3 by 3 to get 9 and 10 by 10 to get 100, and add the two numbers to get 109. 32 + 102 = 9 + 100 = 109
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 sum of the first 5 numbers squared?
The question is ambiguous.Does it want the sum of the squares, or the square of the sum ? They're different.Here are both:1). Sum of the squares: . (1)2 + (2)2 + (3)2 + (4)2 + (5)2 = 1 + 4 + 9 + 16 + 25 = 552). Square of the sum: . (1 + 2 + 3 + 4 + 5 )2 = (15)2 = 225
The sum of the consecutive number of 73?
36+37=73
Which is bigger the sum of the squares of 3 and 5 or the square of the sum of 3 and 5?
sum of squares: 32 + 52 = 9 + 25 = 34 square of sum (3 + 5)2 = 82 = 64 This is a version of the Cauchy-Schwarz inequality.
The product of 2 numbers is 24 and the sum of their squares is 73 create a system of two nonlinear equations?
xy=24 (x^2)+(y^2)=73
How many squares are shaded to show two thirds on a 70 square grid?
70* 2/3 = 46 and 2/3 squares.

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.
What 2 prime numbers sum is 76?
The sum of the two prime numbers 3 and 73 is 76.

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).
What is the sum of 67 plus 3 plus 3?
67 + 3 + 3 = 73
When the sum of a number plus 3 is squared it is 9 more than the sum of the number plus 2 when squares?
2

There is a calculation error.
The sum of the squares of two consecutive odd integers is 34 what are the numbers?
3 and 5
