To determine if the quantities in the data table have a proportional relationship, we need to check if the ratios of water used to time are equivalent for each pair of values.
The data table is as follows:
| 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 entry:
- For 1 min: \( \frac{5 \text{ gal}}{1 \text{ min}} = 5 \)
- For 2 min: \( \frac{10 \text{ gal}}{2 \text{ min}} = 5 \)
- For 3 min: \( \frac{15 \text{ gal}}{3 \text{ min}} = 5 \)
- For 7 min: \( \frac{35 \text{ gal}}{7 \text{ min}} = 5 \)
- For 10 min: \( \frac{50 \text{ gal}}{10 \text{ min}} = 5 \)
Since all of these ratios are equal to 5, the quantities in the data table do represent a proportional relationship.
So the answer is B: Yes, the data table has a proportional relationship.
