Using the $"$lm$"$ function, build a multiple regression model with $"$mpg$"$ as the response and "horsepower" and "origin" as the predictors, store the results in an object called "auto.lm$3",$ and finally, using the "summary" function, print the results as follows:$$

auto.lm$3=$lm$($mpg~horsepower$+$origin$)$

summary$($auto$.$lm$3)$

Find the coefficient of determination of the regression model. Give your answer in four decimal places.$$
