To find the weight of a cheetah that runs 7 miles using the line of best fit given by the equation \( y = 195 - 7.3x \), we can substitute \( x = 7 \) into the equation.
\[ y = 195 - 7.3(7) \] \[ y = 195 - 51.1 \] \[ y = 143.9 \]
So, the weight of a cheetah that runs 7 miles is 143.9 pounds.
Next, we need to determine whether this is an example of interpolation or extrapolation.
- Interpolation occurs when we estimate a value within the range of the data.
- Extrapolation occurs when we estimate a value outside the range of the data.
Looking at the data in the table, the maximum miles run is 8 miles. Since 7 miles is between 1 and 8 miles, this is an example of interpolation.
Thus, the correct response is:
143.9 pounds and interpolation.
