Mark ALL that are TRUE about game theory terminology. Group of answer choices A Nash equilibrium is a strategy profile in which no player can benefit by switching strategies, given that the other player's strategy remains unchanged. A pure strategy is a strategy that is always best. An assignment of strategies to each player is called a strategy profile. A weakly dominant strategy for player A is one that gives a better payoff (than A's other strategies) for more than half of B's possible strategies and lower payoffs (than A's other strategies) for B's other strategies.. A mixed strategy is a randomized policy assigning a probability to each action that the player in question can take.

5. understanding marginal and average tax rates consider the economy of citronia, where citizens consume only oranges. assume that oranges are priced at $1 each. the government has devised the following tax plans: plan a • consumption up to 1,000 oranges is taxed at 50%. • consumption higher than 1,000 oranges is taxed at 20%. plan b • consumption up to 2,000 oranges is taxed at 15%. • consumption higher than 2,000 oranges is taxed at 60%. use the plan a and plan b tax schemes to complete the following table by deriving the marginal and average tax rates under each tax plan at the consumption levels of 300 oranges, 1,200 oranges, and 3,000 oranges, respectively. consumption level plan a plan b (quantity of oranges) marginal tax rate average tax rate marginal tax rate average tax rate (percent) (percent) (percent) (percent) 300 1,200 3,000 complete the following table by indicating whether each plan is a progressive tax system, a proportional tax system, or a regressive tax system. progressive proportional regressive plan a plan b
