Question 40

40.

Is this interpolation or extrapolation?

Extrapolation because 10 is between 8 and 12 pounds.

Interpolation becuase 10 is outside the other data points.

Interpolation because 10 is between 8 and 12 pounds.

Extrapolation because 10 is outside the other data points.

Question 41

41.

Make a scatter plot of the data:

Question 42

42.

Describe the correlation

positive correlation

negative correlation

relatively no correlation

Question 44

44.

Using your equation from #43, predict the gas mileage for a car that weighs 4400 pounds (4.4 thousand pounds). Round to the nearest hundredths place.

Question 45

45.

This is extrapolation because 4.4 is within the data.

This is interpolation because 4.4 is within the data.

This is interpolation because 4.4 is outside the data.

This is extrapolation because 4.4 is outside the data.

Question 46

46.

Question 47

47.

This is interpolation because 30 mpg is within the data.
