The 1st column is the weekend number (1 being the ﬁrst weekend) after the release of the movie, and data is provided for all weekends that the movie remained among the top-ten grossing ﬁlms. 3 For each movie, it is believed that the earnings E(w) during weekend w can be represented approximately by the mathematical formula E(w) = abw where a, b are positive parameters that depend on the movie. For each movie separately, assuming that the formula is correct, write a system of linear equations from which a, b can be determined (you have to make a suitable transformation of the data in order to model this using linear equations).

Formulate the person’s problem using a system of linear equations, ignoring any nonnegative integer requirements on the variables. 7: A person has taken a boat ride on a river from point A to point B, 10 miles away, and back, to point A on a windless day. The river water is ﬂowing in the direction of A to B at a constant speed and the boat always travels at a constant speed in still water.

END 22 Ch. 1. Linear eqs. Example: Example of a curve fitting problem As a numerical example consider the yield y from a chemical reaction, which depends on the temperature t in the reactor. The yield is measured at four diﬀerent temperatures on a specially selected scale, and the data is given below. Temperature t −1 0 1 2 Yield y 7 9 12 10 We will now derive the normal equations for ﬁtting a quadratic function of t to y using the method of least squares. So, the model function is f (t) = a0 + a1 t + a2 t2 , involving three parameters a0 , a1 , a2 .
