To determine if the quantities in the table are in a proportional relationship, we need to check if the ratios of water used to time are equivalent throughout the table. A proportional relationship means that as one quantity changes, the other changes by the same factor.
Let's calculate the ratio of water used (in gallons) to time (in minutes) for each entry and see if they are equivalent:
-
For 1 min:
- Water Used: 5 gal
- Ratio: \(\frac{5}{1} = 5\)
-
For 2 min:
- Water Used: 10 gal
- Ratio: \(\frac{10}{2} = 5\)
-
For 3 min:
- Water Used: 15 gal
- Ratio: \(\frac{15}{3} = 5\)
-
For 7 min:
- Water Used: 35 gal
- Ratio: \(\frac{35}{7} = 5\)
-
For 10 min:
- Water Used: 50 gal
- Ratio: \(\frac{50}{10} = 5\)
All the ratios simplify to 5. Since all the ratios are equivalent, we can conclude that:
Yes, the data table has a proportional relationship.
