Analysis of the relationship between the fuel economy (mpg) and engine size (in liters) for 35 models of cars produces the regression model modifyingabove mpg with caret equals 36.91 minus 3.824 times engine size mpg=36.91−3.824•engine size. explain what the slope means. choose the correct answer below.

The slope of -3.824 means that if we increase engine size by 1 unit, the mpg will decrease by 3.824 units

Explanation:

mpg=36.91−3.824•Engine size

Writing as y=mx+c then

mpg=−3.824•Engine size+36.91

Where mpy represent y, -3.824 represent m, engine size represent x and 36.91 represent c

Since from the equation y=mx+c m is the slope and c is the y-intercept, therefore,

The slope of -3.824 means that if we increase engine size by 1 unit, the mpg will decrease by 3.824 units

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.

a) i only

b) ii only

c) iii only

d) i and ii only
