Answer:
Step-by-step explanation:
Let us assume that if possible in the group of 101, each had a different number of friends. Then the no of friends 101 persons have 0,1,2,....100 only since number of friends are integers and non negative.
Say P has 100 friends then P has all other persons as friends. In this case, there cannot be any one who has 0 friend. So a contradiction. Hence proved
Part ii: EVen if instead of 101, say n people are there same proof follows as
if different number of friends then they would be 0,1,2...n-1
If one person has n-1 friends then there cannot be any one who does not have any friend.
Thus same proof follows.

Answer:

Step-by-step explanation:
Distance between two points is the slope .
Slope =change in y/change in x
Given (-26,0) and (95,0)
x1 = -26
y1 = 0
x2 = 95
y2 = 0
Slope = y2 - y1 / x2 - x1
0-0/95-(-26)
0-0/95+26
0/121
0
