Math: Please help me!!!!!!!!!!!!!!!!?
Math problem: An oceanographer measured the length, in meters, of a deepwater wave and its speed, in meters per second. The results are shown in the following table.
Wave Length (m) Speed (m/s)
100 14.5
125 13.4
130 15.9
175 16.9
210 21.8
350 24.5
400 24.8
(a)
Find the equation of a linear regression line for the data where wave length is the independent variable, x, and speed is the dependent variable. (Round your numerical values to two decimal places.)
ŷ =
(b)
Using the equation from part (a), estimate the speed (in meters per second) of a wave that is 200 m long. (Round your answer to one decimal place.)
