Answer:
10626 different arrangements
Step-by-step explanation:
As we have a total of 23 students and we want to form groups of 3, where the order of the 3 students matters, we can solve this problem using a permutation of 23 choose 3.
The formula for a permutation of n choose p is:
P(n,p) = n! / (n-p)!
So, using n = 23 and p = 3, we have:
P(23,3) = 23! / (23-3)! = 23! / 20! = 23 * 22 * 21 = 10626
So we have a total of 10626 different arrangements of first, second and third place.
Creating a right triangle means that their should always be a right angle at the point you will come up with.
So the unique possible solutions are:
(1,2) and (2,4) => (2,2)
(2,4) and (3,6) => (3,4)
(2,4) and (4,8) => (4,4)
(1,2) and (3,6) => (3,2)
By the way you can notice that if you have two points with coordinates (a,b) and (c,d) the point you are looking is always (c,b) because it is always on a parallel of the x-axis and of the y-axis.
