In this problem, I would say 7.16 to the nearest 10th would be 7.20 because 16 is closer to 20 then 10.
M + n²
= (2) + (-2)²
= 2 + 4
= 6
answer is A. 6
because negative times negative = positive
Answer:
Step-by-step explanation:
Let us assume there are n people in the group. If possible let each have different number of friends.
Number of friends can vary from 0 to n-1 only since no one is a friend of him- or herself, and friendship is symmetrical—if x is a friend of y then y is a friend of x.)
Now n people have friends as 0,1,2...n-1 such that each has distinct number of friends.
But say if A has 0 friends, it means A has no friend,
but there is one B who has n-1 friends i.e. all the others in the party are friends to him including A
This is a contradiction. So it follows in any group of people, two of them have the same number of friends in the group.
