Answer: 2
Step-by-step explanation: :)!
Stance formula : d = sqrt (x2 - x1)^2 + (y2 - y1)^2
(3,5)(7,3)
d = sqrt (7 - 3)^2 + (3 - 5)^2
d = sqrt 4^2 + (-2^2)
d = sqrt 16 + 4
d = sqrt 20
d = 4.47....rounded = 4.5
Let's begin by listing out the information given to us:
There are four students: n = 4
Number of students to be selected: r = 2
To calculate the combination of 2 students to be chosen, we use:

Therefore, there 12 possible combinations from these
