A certain experiment produces the data (1, 1.6), (2, 2.8). (3, 3.2), (4, 3.8), and (5, 4.1). Describe the model that produces a least-squares fit of these points by a function of the form y-81 x + Ī²2xf. Such a function might arise, for example, as the revenue from the sale of x units of a product, when the amount offered for sale affects the price set for the product.
a. Give the design matrix and observation vector for the unknown parameter vector Ī²=
b. Find the associated least-squares curve for the data

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90Ā° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, ā6) is rotated 90Ā° counterclockwise. (x, y) ā (āy, x) 1. switch the x- and y-coordinates: (6, ā3) 2. multiply the new x-coordinate by ā1: (6(ā1), ā3) 3. simplify: (ā6, ā3) .
