State the multiple regression equation that predicts wine quality based on the percentage of alcohol and the type of wine (red, white). Interpret the meaning of the slopes b1 and b2. 10. At a 0.05 level of significance, determine whether each independent variable makes a contribution to the regression model. Then add an interaction term to the model and, again at a 0.05 level of significance, determine whether it makes a contribution to the regression model. Which model is the most appropriate? Explain.

What are the solutions of the system? solve by graphing. y = -x^2 -6x - 7 y = 2

Im literally having a mental breakdown

He graph of f(x) = |x| is stretched by a factor of 0.3 and translated down 4 units. which statement about the domain and range of each function is correct? the range of the transformed function and the parent function are both all real numbers greater than or equal to 4. the domain of the transformed function is all real numbers and is, therefore, different from that of the parent function. the range of the transformed function is all real numbers greater than or equal to 0 and is, therefore, different from that of the parent function. the domain of the transformed function and the parent function are both all real numbers.
