Final answer:
The ratio of dogs to cats is 1:1, as indicated by the equal distribution of ownership (both 8/20, or 0.4) in the apartment complex.
Step-by-step explanation:
The question requires completing a ratio that compares the number of dogs to the number of cats owned by the residents of an apartment complex. From the given data in Solution 2.7, we have:
- Dogs: 8/20 = 0.4
- Cats: 8/20 = 0.4
Since both the number of dogs and cats owned are the same, the ratio of dogs to cats is 1:1. Although we're not given the actual model in the question, based on the provided solution that shows equal portions, we can safely state this ratio. This means there is one dog for every cat owned within the apartment complex.
Note: The sum of all marginal distributions must equal one as mentioned in the solution. Here, both the number of dogs and the number of cats are 40% of the total number of pets, hence the ratio checks out and is correctly simplified.
