t = 'minute'
else:
t = 'minutes'


A. t='minute'+('s'ifx=1else")
B. t='minute'ifx!=1else'minutes'

For the given pseudocode, which XXX and YYY will output the sum of the input
integers (stopping when -1 is input)? Choices are in the form XXX / YYY.
val = Get next input
XXX


while val is not -1
YYY
val = Get next input


Put sum to output
A. sum=val/sum=val
B. sum=0/sum=sum+val
C. sum=0/sum=val
D. sum=val/sum=sum+val


Give this one a try later!

, B. sum=0/sum=sum+val

C. Write 250 lines, run and debug, write 250 lines, run and debug
D. Write 500 lines, run and debug


Give this one a try later!


B. Write 10-20 lines, run and debug, write 10-20 more lines, run and debug,
repeat




What is output?
def calc(num1, num2):
return 1 + num1 + num2


print(calc(4, 5), calc(1, 2))
A. 145 112
B. 9 3
C. 4, 5, 1, 2
D. 10 4


Give this one a try later!


D. 10 4

, Given x = 1, y = 2, and z = 3, how is the expression evaluated? In the choices, items in
parentheses are evaluated first.


(x == 5) or (y == 2) and (z == 5)


A. False OR (True AND False) --> False OR False --> False
B. False OR (True AND False) --> False OR True --> True
C. (False OR True) AND False --> True AND False --> False
D. (False OR True) AND False --> True AND False --> True


Give this one a try later!


a. False OR (True AND False) --> False OR False --> False




Assume a and b are variables that hold the base and height of a right triangle. The
length of the long side (hypotenuse) is calculate as the square root of a^2 + b^2.
Which expression calculates the length of the hypotenuse?
A. math.square_root(aa+bb)
B. math.sqrt(math.pow(aa),math.pow(bb))
C. math.sqrt(math.pow(a,2)+math.pow(b,2))
D. math.pow(math.sqrt(a),2)+math.pow(math.sqrt(b),2)


Give this one a try later!


C. math.sqrt(math.pow(a,2)+math.pow(b,2))




What values are in result_set after the following code is run?
