A car was driven 6 times to measure the distance and the amount of fuel used. The results are as follows: 1 2 3 4 5 6 Distance (km) 20 25 30 35 28 40 Amount of fuel used (L) 2.14 2.75 2.65 3 2.80 2.479 Construct a scatter plot Is there a linear relationship between distance and the amount of fuel used? If so, How would you describe the relationship? What percentage of the variability in the amount of fuel used can be explained by the variability in the distance? Determining the regression line for distance and amount of fuel used.

When granular materials? fall, they form conical piles. The angle of? slope, measured from the? horizontal, at which the material comes to rest is called the angle of repose. The angle of repose is related to the height h and base radius r of the conical pile by the equation ?=cot?1 r h. When a certain granular material is stored in a pile 20 feet? high, the diameter of the base of the pile is 25 feet.
