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 38 mi/h. Round your answer to the nearest degree.

Answer 1

Answer:

$-1\°$

Step-by-step explanation:

Let

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

y ----> the wind chill in °F

we have

$y=-0.36x+12.6$

so

For x=38 mi/h

substitute in the linear equation and solve for y

$y=-0.36(38)+12.6=-1.08\°$

Round  to the nearest degree

$-1.08=-1\°$
