The volume (in cubic feet) of a black cherry tree can be modeled by the equation ŷ = -51.1 +0.3x₁ + 5.3×2, where x₁ is the tree's height (in feet) and x2 is the tree's diameter (in inches). Use the multiple regression equation to predict the y-values for the values of the independent variables. (a) x₁ = 71, x2 = 8.7 (b) x₁ = 65, x2 = 11.7 (c) x₁ = 85, x2 = 17.4 (d) x₁ = 90, x2 = 19.1
