Get started for freeUse the regression capabilities of a graphing utility or a spreadsheet to find linear and quadratic models for the data. State which model best fits the data. $$ (-4,1),(-3,2),(-2,2),(-1,4),(0,6),(1,8),(2,9) $$
Plot the points and determine whether the data have positive, negative, or no linear correlation (see figures below). Then use a graphing utility to find the value of \(r\) and confirm your result. The number \(r\) is called the correlation coefficient. It is a measure of how well the model fits the data. Correlation coefficients vary between \(-1\) and 1, and the closer \(|r|\) is to 1, the better the model. $$ (0.5,9),(1,8.5),(1.5,7),(2,5.5),(2.5,5),(3,3.5) $$
Use the regression capabilities of \(a\) graphing utility or a spreadsheet to find any model that best fits the data points. $$ (0,0.5),(1,7.6),(3,60),(4.2,117),(5,170),(7.9,380) $$
Use a symbolic integration utility to evaluate the double integral. $$ \int_{0}^{1} \int_{0}^{2} e^{-x^{2}-y^{2}} d x d y $$
Evaluate the double integral. Note that it is necessary to change the order of integration. $$ \int_{0}^{3} \int_{y}^{3} e^{x^{2}} d x d y $$
