A company that makes scarves has many different styles and colors that people can order. The company keeps track of the number of each style, color combination they make, and the average sale price for the scarves having that combination. They create a scatter plot
using the data with the number of scarves along the z-axis and the average price per scarf, in dollars, along the Y-axis.
The data in the graph suggest a linear association. Which of the functions best represents the equation of the line of best fit?

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."
