D. Compare your data from this experiment to the data from the experiment on bridges withdifferent numbers of layers. How is the relationship between the number of layers in a bridgeand its breaking weight similar to the relationship between bridge length and breakingweight? How is it different?

For this problem from the graph given we can see that the relationship between Breaking weight and Bridge lenght is inversely proportional (since every time that the Bridge lenght increase the Breaking weight decrease).

And we assume that we have a proportional relationship (higher number of layers higher breaking weight).

So then we can conclude that the relationships are different: number of layers vs breaking weight (proportional) and bridge lenght vs breaking weight (inversely proportional).
