Question

The equation of the trend line is y = −0.36x + 12.6.

Use the equation of the trend line to predict the wind chill for a wind speed of 33 mi/h. Round your answer to the nearest degree.

Answer 1

−1\°

Step by step explation:

Let

x -----> the wind speed in mi/h

y ----> the wind chill in °F

we have

y=-0.36x+12.6y=−0.36x+12.6

so

For x=38 mi/h

substitute in the linear equation and solve for y

y=-0.36(38)+12.6=-1.08\°y=−0.36(38)+12.6=−1.08\°

Round to the nearest degree

-1.08=-1\°−1.08=−1\°
