The Morgan family went to the local arcade. Mr. Morgan bought 3 packages of tokens for his children for $14.94. Later in the day, he decided to buy more tokens and packages. Mr. Morgan needed to know the price for one package, or the unit price, before deciding how many more packages to buy.
1. What is the price of one package?
2. Write a mathematical argument that can be used to defend your solution. (Prove your answer in #1 is correct.)
3. How much would he spend if he bought 5 more packages?
4. Write a mathematical argument that can be used to defend your solution. (Prove your answer in $3 is correct.)

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). =
