Question

describe the relationship between speed and fuel consumption. there is a strong, nonlinear relationship between speed and amount of fuel used. the relationship is negative for speeds up to 60 km/h and positive for speeds beyond 60 km/h. there are no unusual points. there is a strong relationship between speed and amount of fuel used. there are no unusual points. there is a strong, nonlinear relationship between speed and amount of fuel used. there are no unusual points. there is a strong, linear relationship between speed and amount of fuel used for speeds 60 km/h and higher. there are no unusual points. there is a nonlinear relationship between speed and amount of fuel used. the relationship is negative for speeds up to 60 km/h and positive for speeds beyond 60 km/h. there are no unusual points.

Explanation:

By observing the scatter - plot, the points do not follow a straight - line pattern, indicating a nonlinear relationship. For speeds up to 60 km/h, as speed increases, fuel used decreases (negative relationship), and for speeds beyond 60 km/h, as speed increases, fuel used increases (positive relationship). Also, there are no outliers or unusual points.

Answer:

There is a strong, nonlinear relationship between speed and amount of fuel used. The relationship is negative for speeds up to 60 km/h and positive for speeds beyond 60 km/h. There are no unusual points.
