Answer:
Step-by-step explanation:
a) One can get maximum score when all the 20 questions answered are correct.
Maximum score = 20*3 = 60 points
b) Minimum score = 20 * (-2) = -40 points
c) Points for correctly answered questions = 10*3 = 30
Incorrectly answered questions = 14 - 10 = 4
Points for incorrectly answered questions = 4 * (-2) = -8
Total score = 30 + (-8) = 22
d) Points for correctly answered questions =5*3 = 15
Points for incorrectly answered questions = 13 * (-2) = -26
Total score = 15 + (-26) = -11

Answer:
A and D
Step-by-step explanation:
53 + 37 + 44 with the time standard being minutes

134 minutes.
Let's try simplifying it into minutes to find how much we have :
134/60
2 hours and 14 minutes
Therefore A and D are correct.
