Why will the sum of an irrational number and any other number always be irrational?
The proposition is not true.pi and -pi are both irrational. But their sum, = 0, is rational.
What is the sum of 13 x 0?
Any number multiplied by zero will always give the result of zero.
Is the sum of irrational roots irrational?
Not always. For example: sqrt(2)+(-sqrt(2))=0 which is not irrational.
The sum of two quadratic functions will always be quadratic?
No. While the sum of two qudratics cannot have a power greater than two, it could have a power of 2, 1 or 0. x2 + 1 is one quadratic (2-x)(2+x) is another quadratic. Their sum is 1, a constant (power = 0).
Is the sum of two rational numbers is it rational or irrational?
Such a sum is always rational.
What is the sum of residuals for the least square fitted line?
the sum of the residuals is always 0(zero) because its how far they are away from the LSRL. that's what makes them residuals in the first place :P
What residuals do Seinfeld get for each show?
how much in residuals is jason alexander receiving from seinfeld
The sum of the deviations from the mean is always?
0 (zero).
What is two numbers a and -a whose sum is 0?
'a' can be any number whatsoever. The sum of +a and -a is always zero.
Is the sum of a number and its opposite is always negative?
No, it would always equal 0. So if it was like 3 + -3 = 0
When using the least squares method should the column of residuals always sums to zero?
Yes.
Is the sum of two numbers always greater than the larger number?
Not always, if the smaller number is 0 or a negative number. Then their sum will be equal or less than the greater number.
What is the Sum of deviation from the mean is?
The sum of deviations from the mean, for any set of numbers, is always zero. For this reason it is quite useless.
What is weighted residual method?
In estimating a linear relationship using ordinary least squares (OLS), the regression estimates are such that the sums of squares of the residuals are minimised. This method treats all residuals as being as important as others.There may be reasons why the treatment of all residuals in the same way may not be appropriate. One possibility is that there is reason to believe that there is a systematic trend in the size of the error term (residual). One way to compensate for such heteroscedasticity is to give less weight to the residual when the residual is expected to be larger. So, in the regression calculations, rather than minimise the sum of squares of the residuals, what is minimised is their weighted sum of squares.
What is the sum of 0 mutliplied -7?

The sum of any number and 0 is?
Depends what the number is. If you were multiplying and did (substitute Z with any number)0xZ,the answer would always be zero. Actually the SUM is the answer to a addition problem. So the answer would be the number in which is to 0.
