In summary, the number of handshakes at a UN meeting can be calculated using the formula n(n-1)/2, where n is the number of people in attendance. It is seen as a measure of interaction and cooperation between world leaders, but it is not a reliable measure of international relations. The maximum number of handshakes can only be achieved when every person present shakes hands with every other person. If the number of people at the UN meeting increases, the number of handshakes will also increase.

at a United Nations meeting, a group of 15 delegates meet to discuss an international peace treaty. If all of the delegates shake hands with one another, how many handshakes are exchanged?

That should be straight forward. In a group of n people each person shakes hands with the n-1 other people. That would be a total or n(n-1) except that each had shake involves two people. The total number of hand shakes is n(n-1)/2.

## 1. How is the number of handshakes at a UN meeting calculated?

The number of handshakes at a UN meeting can be calculated using the formula n(n-1)/2, where n is the number of people in attendance. In this case, n=15, so the number of handshakes would be (15*14)/2 = 105.

## 2. Why is the number of handshakes important at a UN meeting?

The number of handshakes can be seen as a measure of the level of interaction and cooperation between world leaders at the UN meeting. It also reflects the number of connections and relationships being formed between individuals and countries.

## 3. Is it possible to have more than 15 handshakes at a UN meeting?

No, it is not possible to have more than 15 handshakes at a UN meeting with only 15 people in attendance. The maximum number of handshakes can only be achieved when every person present shakes hands with every other person, which is represented by the formula n(n-1)/2.

## 4. How does the number of handshakes change if more people attend the UN meeting?

If the number of people at the UN meeting increases, the number of handshakes will also increase. The relationship between the number of people (n) and the number of handshakes (n(n-1)/2) is directly proportional, meaning that as one value increases, the other value also increases.

## 5. Is the number of handshakes at a UN meeting a reliable measure of international relations?

The number of handshakes at a UN meeting can provide some insight into the level of interaction and cooperation between world leaders, but it should not be considered as a sole measure of international relations. Other factors such as agreements, resolutions, and diplomatic relations should also be taken into consideration.
