Chapter 1: Lesson 1.10 Mathematical Modeling & Relations HW #18(b): Find the equation of the regression line using a calculator.
Direct Variation #21) If y is directly proportional to x and x = 10 when y = 2050, find a linear model that relates x and y. Inverse Variation See Homework #33
Joint Variation If z varies jointly as x and y then z = kxy (where k is a constant) #46 What would be a mathematical model for “z varies jointly as the square of x and the cube of y? #60 What would be a mathematical model for “P varies directly as x and inversely as the square of y? What is the constant if P = 28/3 when x = 42 and y = 9?
