Modelling Applications

Multiple Choice

Which of the following is NOT an advantage of using computer models?

• They are less expensive than building the real thing.

• They allow for various scenarios to be tested safely.

• They can predict the behavior of systems with complete accuracy.

• They can be faster than real-life applications.

Multiple Choice

What is a potential disadvantage of using models as mentioned in the text?

• Models can be faster than doing the real thing.

• Models can sometimes be more expensive than building the real thing.

• Models are only as good as the data entered into them.

• Models always accurately predict future behavior.

Multiple Choice

People's reactions to the results of a simulation may not always be positive because:

• They trust the computer model more than the real thing.

• There will always be a difference between the results from modeling and reality.

• The computer models are too expensive.

• The simulations take too long to run.

Multiple Choice

What is the main purpose of using a spreadsheet for personal finance modeling?

• A) To predict weather patterns.

• B) To model the sales of a tuck shop in a school.

• C) To simulate traffic flow.

• D) To design bridges and buildings.

Multiple Choice

According to Figure 6.6 in the text, if the 'Total Profit' is negative, what does it indicate?

• A) The tuck shop made more profit than loss.

• B) The tuck shop has a good stock inventory.

• C) The tuck shop sold out all items.

• D) The tuck shop made a loss.

Multiple Choice

In bridge and building design, why are computer models essential before construction?

• A) They are used for creating advertisements.

• B) They ensure the design meets criteria under various scenarios.

• C) They are cheaper than wind-tunnel tests.

• D) They replace the need for engineers.

Multiple Choice

What factors does a modeler have to consider when building a bridge?

• A) The color and design of the bridge.
