Answer:
The given situation is an example of ultimatum game.
Explanation:
The ultimatum game is a popular experiment. It is widely used in economic experiments. In this game two people are matched randomly, one player as a proposer and one as a responder. They are told they would play a game exactly once. The proposer is given an amount of money and he has the task to split or divide that amount between himself and the responder. When the proposer conveys the decision, the respondent then decides whether to accept or reject it. If the responder accepts, then both earn the amount split per the proposer's suggestion. If responder rejects then both the proposer and responder receive nothing.
For example a player is given a sum of money, $ 20. He is called proposer. He is told to offer some endowed amount (from $1 to $20) to the other player who is responder. If responder accepts this amount offer they both keep that money but if the responder rejects the offer then both players get nothing.
A proper fraction is a fraction whose numerator is less than the denominator.
The answer is C. 4/17 is a proper fraction.
A, B, and D are improper fractions.
The building is 76 feet tall. Notice that there's a pair of similar triangles in this diagram: The top of the building, root of the building, and the stake form triangle 1. The top of the tree, root of the tree, and the stake form triangle 2. Since the root of the tree is half way between stake and building, the proportionality between the triangles is 2. Therefore, the building is twice as tall as the tree. 38*2=76.
