D isn't the correct answer; the fact that adults are the target population doesn't validify anything.
C doesn't entirely prove its point because there are other factors that go into the game being biased.

Their data will only pertain to fans of the 2 teams playing each other, and not represent the population as a whole.
A would be my answer for reasons stated above.
Answer:
The answer of this question is 78°.
Step-by-step explanation:
Let angle X be denoted by y then angle Z=y (because isosceles angles of a traingle is equal)
Now,
y+y+24°=189°
2y+24°=180°
2y=180°-24°
y=156/2
y=78°
Answer:

Step-by-step explanation:
Given expression is 
Let us perform the operations inside the parentheses first.
