To determine the weight of a cheetah that runs 7 miles using the line of best fit 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 if this is an example of interpolation or extrapolation.
-
Interpolation occurs when we estimate a value within the range of the given data. In this case, the data points you provided include distances of 1, 3, 5, 8, and 10 miles. Since 7 miles falls between the existing data points of 5 miles (145 pounds) and 8 miles (135 pounds), this is considered interpolation.
-
Extrapolation occurs when we estimate a value outside the range of the given data.
Thus, we conclude:
- The weight of a cheetah that runs 7 miles is 143.9 pounds.
- This is an example of interpolation.
