AP CSP Boolean Logic 5

The two variables age and day are initialized with the values shown.

age <-- 16

day <-- "Monday"

Choose the compound conditional that evaluates to false.

• ( (age = 16) AND ( NOT (day = "Tuesday") ) ) AND (day = "Monday")

• ( (age = 16) AND (day = "Tuesday") ) OR (day = "Monday")

• ( (age > 10) AND ( (age + 5) > 25 ) )

• NOT ( (age = 16) AND (day = "Tuesday") )

The following expression is from the data loading logic of a website.

NOT ( state ≠ "loading" AND result = "error" )

Which of these expressions are logically equivalent?

• state ≠ "loading" AND result ≠ "error"

• state = "loading" AND result = "error"

• state = "loading" OR result ≠ "error"

• state ≠ "loading" OR result = "error"

This program uses a nested conditional to recommend a heat level for cooking eggs.

In which situations will heatLevel be "medium"?

Note that there may be multiple answers to this question. Choose all answers that apply:

• When inHurry is false and eggDish is "fried"

• When inHurry is true and eggDish is "fried"

• When inHurry is false and eggDish is "scrambled"

• When inHurry is true and eggDish is "scrambled"

The following circuit takes the output of an OR gate and sends it through a NOT gate. This circuit is logically equivalent to the NOR logic gate, a common gate in computers.

Select the output column that correctly completes out the truth table for the circuit:

• 0

Trace the code and plot the movements of the robot for the 3 scenarios.

If the robot is directed to move onto a black square, it “crashes” and the program ends.

Choose the scenario that results in a "crash."

• 
• 
• 

In the program below, the initial value of x is 5 and the initial value of y is 10.

What is displayed as a result of running the program?

• Foxtrot

• Hotel

• November

• Yankee

The diagram shows a circuit composed of two logic gates labeled OR and AND. Each gate takes two inputs and produces a single output.

If the inputs A and C are both false, which of the following best describes the output of the AND gate?

• The output will be true no matter what the value of input B is.

• The output will be false no matter what the value of input B is.

• The output will be true if input B is true; otherwise it will be false.

• The output will be false if input B is true; otherwise it will be true.

The diagram below shows a circuit with three gates, where the output from two OR gates are sent into a third OR gate. The circuit has four inputs (A, B, C, D), two for each OR gate.

If the final output is 1, what is NOT a possible state of the inputs A/B/C/D?

• A = 0, B = 1, C = 0, D = 0

• A = 1, B = 0, C = 1, D = 0

• A = 1, B = 1, C = 0, D = 1

• A = 1, B = 0, C = 1, D = 1

• A = 0, B = 0, C = 0, D = 0

The two variables age and day are initialized with the values shown.

age <-- 16

day <-- "Tuesday"

Choose the compound conditional that evaluates to false.

• (age > 10) AND (age < 20)

• NOT (age > 10)

• (day = "Tuesday") OR (age < 12)

• NOT ( (age = 16) OR (day = "Monday") )
