Use the multiple regression equation to predict a person's salary. Assume that the variable A is the number of years of college. Assume that the variable B is the number of years of experience. Suppose the person has 7 years of college and 3 years of experience. What should their salary be?

To use the multiple regression equation to predict a person's salary, you will need the specific equation which includes the coefficients corresponding to the variables "A" (number of years of college) and "B" (number of years of experience). Without the equation or specific coefficients, I cannot give you an accurate prediction.

However, if you have the multiple regression equation with the corresponding coefficients, you can predict the person's salary by substituting the values of "A" and "B" into the equation. The equation will look something like this:

Salary = a + b1A + b2B

where "a" is the intercept, b1 is the coefficient for variable A, and b2 is the coefficient for variable B. Plug in the values of A=7 and B=3, and calculate the prediction using the equation. The result will be the predicted salary for the person with 7 years of college and 3 years of experience.
