A linear regression is done on data the line of best fit is y= 1.25x-6.25. What is the residual for the point (1,1)?

Damm [24]

Answer:

Step-by-step explanation:

Find the predicted y value when x=1:

$\hat{y}=1.25x-6.25\\\hat{y}=1.25(1)-6.25\\\hat{y}=1.25-6.25\\\hat{y}=-5$

Find the residual:

$\text{Residual}=\text{Actual Value}-\text{Predicted Value}\\\text{Residual}=y-\hat{y}\\\text{Residual}=1-(-5)\\\text{Residual}=1+5\\\text{Residual}=6$

Because our residual is positive, this is an indicator that our predicted y value is too low.

Perform the indicated operation. X^3+43-49x-7x^2 divides by x^2-49

BaLLatris [955]

Answer:

The quotient is: x-7

and remainder is : -300

Step-by-step explanation:

We need to divide $X^3+43-49x-7x^2$ by $x^2-49$

First arrange the term $X^3+43-49x-7x^2$ in terms of ascending order of x.

Arranging we get:

$x^3 - 7x^2 -49x + 43$ \ $x^2-49$

The division steps are shown in figure attached.

The quotient is: x-7

and remainder is : -300
