D. All students in each grade. It can't be A since the survey is for the students, it defeats the purpose. It can't be B and C since those are too biased. Basing the student population on one factor like gender and sports is not logical in the context of this survey.
X + y = 3500 -------------- (1)
x - y = 2342 --------------- (2)
(1) + (2):
2x = 5842
x = 2921 -------------- Sub into (1)
x+ y = 3500
2921 + y = 3500
y = 3500 - 2921
y = 579
----------------------------------------------
Answer: x = 2921, y = 579

Answer:
<em>21/50</em>
Step-by-step explanation:
Fraction that voted for team A = 7/10
Fraction of those that wear red cap = 3/5 of fraction of team A
Fraction of those that wear red cap = 3/5 of 7/10
Fraction of those that wear red cap = 3/5*7/10
Fraction of those that wear red cap = 21/50
<em>Hence the fraction of people that wear red cap is 21/50</em>
