3.
Given the linear model 3x - 10y = -(-3), what value of y is predicted when x=2? Round to the nearest hundredth
4.
Given the linear model -6x + 11y = 7, the "Fit" when x=9 would be...? Round to the nearest hundredth.
5.
The following linear model is created: y = -7x+8. What is the predicted value of the dependent variable when the independent variable has a value of 2.8?
Homework Answers
1)
Predicted value of y when x = 0 is -1/7
Thus, the residual = 7 - (-1/7) = 50/7 = 7.14
2)
The "Fit" when x = -1 is (3*-1 + 8) = 5
3)
The predicted value of y when x = 2 is (3*2 - 3)/10 = 0.30
4)
The "Fit" when x = 9 is (7 + 6*9)/11 = 61/11 = 5.55
5)
The predicted value of the dependent variable, y when the independent variable, x = 2.8 is (-7*2.8 + 8) = -11.6
