Answer:
15504 different groups
Step-by-step explanation:
We have a total of 20 people, and we want to know how many groups of 5 people we can make, where the order of the people inside the group doesn't matter, so we can solve this question calculating the combination of 20 choose 5.
The formula for combination is:
C(n, p) = n! / (p! * (n-p)!)
In this case, we have n = 20 and p = 5, so:
C(20, 5) = 20! / (5! * 15!) = 20*19*18*17*16 / (5*4*3*2) = 15504
So we have 15504 different groups.
It's a 45-45-90 triangle,
where the legs are congruent, and the hypotenuse is sqrt(2) times the length of a leg.
I think it's equal

It’s 9 because the whole number is eight, but seven is going to bring the number up ( five or more raise the score, four or less let it rest.) Good luck !
