To determine if the quantities in the data table are in a proportional relationship, we can check if the ratios of the number of apples to the number of trees are constant.
Let's calculate the ratios for each pair of values:
-
For 2 trees and 26 apples: \(\frac{26}{2} = 13\)
-
For 3 trees and 39 apples: \(\frac{39}{3} = 13\)
-
For 6 trees and 78 apples: \(\frac{78}{6} = 13\)
-
For 10 trees and 130 apples: \(\frac{130}{10} = 13\)
-
For 12 trees and 156 apples: \(\frac{156}{12} = 13\)
Since all these ratios equal 13, the quantities in the data table are indeed in a proportional relationship.
Therefore, the correct response is: Yes, the data table has a proportional relationship.
