Step-by-step explanation:
Given




Solving (a): Number of students
Represent students with S and non students with N
So:
--- (1)
--- (2)

Answer:
A: sqrt(11)
B: 4.2
C: sqrt(26)
Step-by-step explanation:
First, 4^2 = 16
That means that sqrt 11 is smaller than 4.2 (a value greater than 4). This is because sqrt16>sqrt11.
Sqrt(26) is greater than sqrt(25) = 5. That means that it's greater than 4.2.
Hence, the order given above.
