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 expressesmass as a function of the volume.

grams	Volume in ml
14	38.3
16.5	43.9
19	52.6
21.5	57.1
24	65.7
26.5	72.6
29	78.6

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 12, using yourun-rounded regressionequation find its predicted volume. Round your answer to 1 decimal place. mL _________
