Algebra Problems -- Residuals and Polynomials

[threemonkeys]

Thank you to everyone willing to view this and help out!

33) Use residuals to determine whether the model is a good fit for the data in the table. Explain.
y=2x+1
(Table)
x | -4 | -3 | -2 | -1 | 0 | 1 | 2 | 3 | 4 |
y | -11 | -8 | -5 | -4 | -1 | -1 | 2 | 6 | 5 |

93)
Each of two cats has one black patch gene (B) and one tan patch gene (t). Any gene combination with a B results in black patches. The punnett square shows the possible gene combinations of the offspring and the resulting patch colors.

B t
B BB Bt
t Bt tt

a) Show how you could use a polynomial to model the possible gene combinations of the offspring.

What were the residuals that you calculated?

Hello threemonkeys. Please don't post lists of exercises with no efforts shown. (Also, post one exercise per thread.) Tutors would like to see how far you got, in each exercise, so include whatever you've done so far. Can you identify parts you don't understand? Ask specific questions, about the points where you're stuck.
