Predicting y-Values In Exercises 1 4, use the multiple regression equation to predict the y-values for the values of the independent variables.Elephant Weight The equation used to predict the weight of an elephant(in kilograms) isyn = -4016 + 11.5x1 + 7.55x2 + 12.5x3 where x1 represents the girth of the elephant (in centimeters), x2 represents thelength of the elephant (in centimeters), and x3 represents the circumference ofa footpad (in centimeters). (Source: Field Trip Earth)(a) x1 = 421, x2 = 224, x3 = 144(b) x1 = 311, x2 = 171, x3 = 102(c) x1 = 376, x2 = 226, x3 = 124(d) x1 = 231, x2 = 135, x3 = 86
