Final answer:
The production of 3,500 iPads and 1,500 HDTVs is unattainable and lies outside the production possibilities frontier, indicating that producing this combination of goods exceeds the capacity of current resources.
Step-by-step explanation:
The production of a combination of 3,500 iPads and 1,500 HDTVs, according to the table provided, lies outside of the production possibilities frontier (PPF). The PPF represents different combinations of goods that can be produced with the available resources at the full capacity of production. When a point is on the PPF curve, it indicates full utilization of resources. However, any point outside the curve, such as the given combination of 3,500 iPads and 1,500 HDTVs, is unattainable with the current resources and technology. Such a point reflects the unattainability aspect of the PPF, illustrating that the production exceeds the capacity of the resources.
