Lucy earns 52 dollars each week working part-time at a bookstore. She earns one additional dollar for each book that she sells. Let 'A' be the amount (in dollars) that Lucy earns in a week if she sells 'B' books.

Write an equation relating A to B . Then use this equation to find the amount of money Lucy earns if she sells 15 books.

Given are five observations for two variables, x and y. xi 1 2 3 4 5 yi 3 7 5 11 14 which of the following is a scatter diagrams accurately represents the data? what does the scatter diagram developed in part (a) indicate about the relationship between the two variables? try to approximate the relationship betwen x and y by drawing a straight line through the data. which of the following is a scatter diagrams accurately represents the data? develop the estimated regression equation by computing the values of b 0 and b 1 using equations (14.6) and (14.7) (to 1 decimal). = + x use the estimated regression equation to predict the value of y when x = 4 (to 1 decimal). =
