To determine whether the bear population is proportionally related to the number of years, we need to check the ratios of the bear population to the number of years.
We can calculate the ratios for each given time:
-
For 1 year: \[ \text{Ratio} = \frac{6 \text{ bears}}{1 \text{ year}} = 6 \]
-
For 20 years: \[ \text{Ratio} = \frac{120 \text{ bears}}{20 \text{ years}} = 6 \]
-
For 60 years: \[ \text{Ratio} = \frac{240 \text{ bears}}{60 \text{ years}} = 4 \]
The ratios for the first two rows (1 year and 20 years) are both 6, while the ratio for the last row (60 years) is 4.
Since the ratios are not all the same, this indicates that the bear population is not proportionally related to the number of years.
Therefore, the correct response is: The bear population is not proportionally related to the number of years because the ratio in the last row is not equal to the ratios in the first two rows.
