The Big Telescope Company sells circular mirrors. Their largest mirrors have radii of 5 meters and their smallest mirrors have radii of 1 meter. The cost of every mirror is proportional to the cube of the mirror's radius. What is the ratio of the total cost of 25 of the company's smallest mirrors to the cost of one of the company's largest mirrors? Express your answer as a common fraction.

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). =
