To determine if the quantities in the table represent a proportional relationship, we need to check if the ratios of water used to time are constant throughout the table.
The given data is:
| Time (min) | Water Used (gal) | |------------|------------------| | 1 | 5 | | 2 | 10 | | 3 | 15 | | 7 | 35 | | 10 | 50 |
Now, let's calculate the ratios of water used to time for each pair:
- For 1 min: \( \frac{5}{1} = 5 \)
- For 2 min: \( \frac{10}{2} = 5 \)
- For 3 min: \( \frac{15}{3} = 5 \)
- For 7 min: \( \frac{35}{7} = 5 \)
- For 10 min: \( \frac{50}{10} = 5 \)
Since all the ratios are equal to 5, the quantities are indeed in a proportional relationship.
Thus, the correct response is:
Yes, the data table has a proportional relationship.
