<span>A volcano that expels highly viscous magma is a greater threat to life and property because it is more explosives and thus is more difficult or impossible to predict. When there are more explosives happen, the damage that created to nearby life and poverty will also be increased. Depending on the amount of magma that being erupted, it might take more than ten years for the soil to have good enough composition for plants to grow.</span>
Answer:
False.
Explanation:
The concept of "Nash equilibrium" is been by economist and also by "gamers" in game theory. Nash equilibrium is so good for making decisions and the determination of strategies.
In playing this game, the players or participants can use the pure strategy or the mixed strategy. The mixed strategy is the use of different strategies randomly.
"If a player chooses a mixed strategy in a Nash equilibrium, this implies that the payoff from using that mixed strategy is the same as the payoff from using any of the pure strategies in it".
The statement given above is FALSE because the PAYOFF WILL INCREASE IF WE ARE TO PLAY A MIXED STRATEGY.
For instance if we have a head of 1 and -1, and a tail of -1 and 1, the payoff for pure strategy is likely one or minus one but for a mixed strategy it could be zero.
Answer: d. Regulate the firm's pricing behavior.
Explanation:
One way the government can regulate monopolies is to protect the interests of the consumers who are usually the end users. The government have the market power to set prices higher than normal in a competitive market. Thjs can be achieved by Price capping or limiting price increases. As this helps Regulate the firm's pricing behavior.
Wher do we choose the communication planning and resource?
The question is incomplete. The complete question is :
A manufacturer believes that the cost function : 
approximates the dollar cost of producing x units of a product. The manu- facturer believes it cannot make a profit when the marginal cost goes beyond $210. What is the most units the manufacturer can produce and still make a profit? What is the total cost at this level of production?
Solution :
Given the cost function is :
Now, Marginal cost = 
So, if the marginal cost = $ 210, then the manufacturer also makes a profit and if it goes beyond $ 210 than the manufacturer cannot make a profit.
Therefore, we have to equate : 
So when x = 45, then C(x) = $ 8042.5
Therefore, the manufacturer 
to 45 units and 
This leads to a total cost of $ 8042.5
