Decide whether statements (a) through (e) are true or false. Justify each answer. Assume A is an mtimesn matrix and Bold b is in set of real numbers R Superscript m. a. The general least-squares problem is to find an Bold x that makes Upper A Bold x as close as possible to Bold b. Choose the correct answer below. A. The statement is false because the general least-squares problem attempts to find an Bold x such that Upper A Bold xequalsBold b. B. The statement is true because the general least-squares problem attempts to find an Bold x that minimizes

Asays "we are both knaves" and b says nothing. exercises 24–31 relate to inhabitants of an island on which there are three kinds of people: knights who always tell the truth, knaves who always lie, and spies (called normals by smullyan [sm78]) who can either lie or tell the truth. you encounter three people, a, b, and c. you know one of these people is a knight, one is a knave, and one is a spy. each of the three people knows the type of person each of other two is. for each of these situations, if possible, determine whether there is a unique solution and determine who the knave, knight, and spy are. when there is no unique solution, list all possible solutions or state that there are no solutions. 24. a says "c is the knave," b says, "a is the knight," and c says "i am the spy."
