Final answer:
Without the total number of houses and the number of those in Pinewood Estates, it is impossible to determine the proportion of houses built there. The question requires statistical data to calculate the percentage.
Step-by-step explanation:
The question asks about the proportion of houses built in Pinewood Estates. This is a mathematics question focused on finding percentages, which falls under the category of statistics and probability. To answer the question accurately, one would need to know the total number of houses being considered and the number of those houses that were built in Pinewood Estates. Without this information, it is not possible to determine the correct proportion or percentage.
As an example in determining proportions, if you have a sample where 50% of items are one type and 50% are another type, you would conclude that half of the items belong to each type. Similarly, if 75% of items were of one type and 25% were another, three-quarters of the items would be the first type and a quarter would be the second type. However, this example does not provide the specific answer to the question about Pinewood Estates, since the necessary data is not available in the question.
