We say that a set of system specifications is consistent if there is a way for all the specifications to be simultaneously true. Otherwise, the set of specifications is inconsistent. Consider the following set of system specifications:

If the file system is not locked, then new messages will be queued.

The file system is not locked if and only if the system is functioning normally.

If new messages are not queued, then they will be sent to the message buffer.

If the file system is not locked, then new messages will be sent to the message buffer.

New messages will not be sent to the message buffer.

Use propositional logic to determine if the set of system specifications consistent or inconsistent by doing the following:

Part a (2 pts) : First, define the appropriate propositional variables for representing the system specifications.

Part b (2.5 pts) : Then, translate each of the system specifications into propositional logic using the propositional variables you defined in part a.

Part c (2.5 pts) : Finally, is the set of system specifications consistent or inconsistent? Justify your answer.

Let A be a set of real numbers. We say that A is an open set if for every x0 ∈ A there is some δ > 0 (which might depend on x0) such that (x0 − δ, x0 + δ) ⊆ A. Show that a set B of real numbers is closed if and only if B is the complement of some open set A

Explain what we mean when we say that the economy exists in an ecological system. How can we add the natural capital in a circular flow diagram, and why is it important? Discuss how the concept of negative externalities and property rights are related to pollution and resource degradation.

Which of the following explanation is NOT consistent with fixed exchange rate system?

Which of the following explanation is NOT consistent with fixed exchange rate system?a. Central banks do not need foreign currency reserve at all.b. Under fixed exchange rate system, inflation can easily be spread among trading partners.c. Relatively easy to forecast exchange rate and thus it is helpful to increase trade.d. As the structure of a nation’s economy changes, the exchange rate should eventually be changed. But fixed system restricts this adjustment of relative price and the internal balance of payment...
