An unknown metal has been found and the following experimental results have been tabulated in the table below. The table contains the grams of the unknown metal and the volume in milliliters of water displacement. Find a linear model that expresses mass as a function of the volume.


grams Volume in ml
19 134.2
21.5 154.9
24 167.8
26.5 189.1
29 209
31.5 220.3
34 245



A) Write the linear regression equation for the data in the chart.

Volume = x+ where x is the grams of the unknown metal. Round your answers to 3 decimal places

B) If the mass of an unknown metal is 17, using your un-rounded regression equation find its predicted volume. Round your answer to 1 decimal place.    mL
