Question

The equation of the trend line is y = -0.36x + 12.6 use the equation to of the trend line to predict the wind chill for a wind speed of 51 mi/h round your answer to the nearest degree. The wind chill at 51 mi/h

Answer 1

Given:

The equation of the trend line is:

`y=-0.36x+12.6`

In this equation y represents the wind chill and x represents the wind speed.

To find:

The wind chill at 51 mi/h.

Solution:

We have,

`y=-0.36x+12.6`

Putting
`x=51`, we get

`y=-0.36(51)+12.6`

`y=-18.36+12.6`

`y=-5.76`

Round the answer to the nearest degree.

`y\approx -6^\circ`

Therefore, the wind chill at wind speed 51 mi/h is -6°.
