Given the following code

x = 5 y = 5 if (x >5) or (y >5): print('A') else: print('Z') 

Which of the following is an equivalent program? (See DeMorgan Laws document )

x = 5 y = 5 if not(x >5) and not(y >5): print('A') else: print('Z')	x = 5 y = 5 if not(x > 5) and not(y > 5): print('Z') else: print('A')
x = 5 y = 5 if not(x >5) or not(y >5): print('A') else: print('Z')	x = 5 y = 5 if (x >5) and (y >5): print('Z') else: print('A')

What would be printed if the following python code was executed

Students are required to take two tests and write a review paper in a course. However, students who score 90 or above in both tests do not have to write the review paper. Which of the following python statements correctly determines whether a student needs to write a paper?

A.

if test1 < 90 and test2 < 90:

print('you need to write the review paper')

else:

print('you do not need to write the review paper')

B.

if test1 >= 90 or test2 >= 90:

print('you do not need to write the review paper')

else:

print('you need to write the review paper')

C.

if test1 < 90 or test2 < 90:

print('you need to write the review paper')

else:

print('you do not need to write the review paper')

D.

None of the code above correctly determines if you need to write a paper
