Next, use a graphing calculator to find the model that best expresses the height and vertical velocity of the rubber ball. We can also use this model to predict the maximum height of the ball and its vertical velocity when it hits the face of the CBR. Fit linear, quadratic, cubic, and power functions to the data.

regression equations. In this packet you will be calculating different regression equations. (Each problem will tell you which regression equation to calculate) Your calculator will find the equation for you. After we find the equation to represent the points (data), we need to know how well the equation matches the data.

So the equation of the regression line of y on x is: y = 30.66 + 0.688x. For the regression line of x on y: (to 3 s.f.) So the equation of the regression line of x on y is. x = 11.70 + 0.895y. Both lines must pass through the mean point (101.875, 100.75). c) Both variables are random variables. To find x when y = 100, we use the regression line ...

Use Stat > Regression > Regression to find the regression equation AND predict BAC when “beer” is 5. To predict the values, use Options and then type in the x value of your variable there. Use Stat > Regression > Regression to find the regression equation AND make a residual plot of the residuals versus the explanatory variable.
