There is actually a lot of wan technologies that are carried over the pstn. But the first thing we have to do, is to know what does the pstn means. The pstn means Public Switched Telephone Network. Though they have some similarities, the atm and the wan are different machines.
Answer:c
Explanation:
Since there’s a reduction in dollar then they will be a reduction in price thereby increasing demand
The correct answer is B.
A price floor is a policy established by economic authorities that consists on setting a threshold so that the price of a certain product or service cannot decrease under that. It distorts the market outcome when it is larger than the equilibrium price, because the amount supplied at the price floor level would the larger than the amount demanded by consumers and, hence, there is an excess of supply or surplus. Therefore, <u>the market does not clear because the rationing function of prices has been externally influenced. </u>
A price ceiling is a similar policy established by economic authorities. A threshold is set so that the price of a certain product or service cannot increase over it. It distorts the market outcome when it is smaller than the equilibrium price, because the amount supplied at the price ceiling level would the smaller than the amount demanded by consumers and, hence, there is an excess of demand of shortage. Again, <u>the market does not clear because the rationing function of prices has been externally distorted. </u>
<em>A market clears when the equilibrium is reached and the amount supplied equals the amount demanded, so that the desires of both producers and consumers meet. </em>
Answer:
22 days
Explanation:
number of activities : 3 ( A,B,C)
connected via : SS and FF combination. days lag on SS and F = 2
Durations : 5,10 and 3
A and B is connected by SS and there is a 2-day lag on the SS connection, this means that B will start 2 days after A have ended
i.e when T = 0 , B will start : 5 +2 = 7 days and end in 17 days
while B and C is connected by FF and there is also a 2-day lag on the FF connection, this means that C will start after B has ended and end in 2 days
i.e when B ends at 17 days ; C starts = 17 + 2 = 19 DAYS
hence the project will end in 19 + 3 = 22 days ( i.e when C ends )
