Part of a regression output is provided below. Some of the information has been omitted.
quester [9]

Answer:

301.189

Step-by-step explanation:

Given the table :

Source of Variation - - SS - - - df - - - MS - - - - F

Regression - - - - - -3177.17 - - -2 - - 1588.6

Residual - - - - - - - - ______ --17 - - -17.717

Total - - - - - - - - - - 3478.36 - - 19

Calculate the SSR, Sum of Square residual

The Sum of Square RESIDUAL (SSR), Mean Square Residual (MSR) and Degree of Freedom RESIDUAL (DFR) are related by the formular :

MSR = SSR / DFR

Hence,

SSR = MSR × DFR

Fr the table ;

MSR = 17.717 ; DFR = 17

SSR = (17.717 × 17)

SSR = 301.189

A polynomial function g(x) with integer coefficients has a leading coefficient of 1 and a constant term of
mart [117]

Answer:

+1, -1, +11, -11

probably written with a +- symbol:

+-1, +-11

Maybe (silly) written like fractions:

+- 1/1, +- 11/1

Step-by-step explanation:

First list the factors of the leading coefficient. Here its 1. So we're going to use positive and negatives of the factors of 1, which is just +/- 1 . These numbers are going to go on the bottom of a fraction.

Next look for the factors of the constant, here it's 11

So that gives us

+/- 1, +/- 11 . These will go on the top of a fraction. (A fraction is a rational expression, that's why the name)

Then make all the combinations of

factors of constant

OVER

factors of leadingcoeff

So, we find

+/- 1, +/- 11
