Answer:
The answer is: As described in the question, North Korea is one of the poorest countries in the world, and it is expensive to train doctors to perform eye surgery. In a poor country, the labor cost of the doctor will not be that large but doctors need very specific and expensive equipment to perform eye surgeries. North Korea probably cannot afford to purchase the equipment necessary for performing eye surgeries.
If purchasing power parity holds, when a country's central bank decreases the money supply, its <u>If purchasing power parity holds, when a country's central bank decreases the money supply, its price level (rises/falls) and its currency (appreciates/depreciates) relative to other currencies in the world. </u>
A theory of exchange rate determination and a means to compare average prices of goods and services between nations is purchasing power parity (PPP).
According to the hypothesis, fluctuations in the spot exchange rate are caused by importers' and exporters' actions, which are prompted by variations in prices across nations.
Alternatively, PPP contends that changes to a nation's current account may have an impact on the value of the currency's exchange rate on the foreign exchange (Forex) market.
In contrast, the interest rate parity theory postulates that fluctuations in the exchange rate are caused by investor actions (whose transactions are reported on the capital account).
The "law of one price" as it pertains to the overall economy is the foundation of PPP theory.
Hence, option A and D is correct.

Answer:
22.49 g of NH3
Explanation:
The balanced equation for this would be:
3H₂+N₂ → 2NH₃
So let's take note of this:
We will need 3 moles of H₂ to produce 2 moles of NH₃.
Now let us convert:
First we determine the molar mass of H2:
Element:
number of atoms x molar mass
H = 2 x 1.01 g/mol = 2.02 g/mol
Let's see how many moles of H2 there are in 4.00g
Now we can see how many moles of NH₃ we can make given the ratio and convert it again to grams by getting the molar mass of NH₃:
This means that with 1.98 moles of H₂, we produce 1.32 moles of NH₃
So let's get the molar mass of NH₃ so we can convert it to grams:
N = 1 x 14.01 = 14.01
H = 3 x 1.01 = 3.03
17.04g/mol
Answer:
14.91 and 24.77%
Explanation:
The computation of the company interest coverage ratio is shown below:-
Interest coverage ratio = Earning before interest and tax ÷ Interest
= $161,000 ÷ $10,800
= 14.91
Operating profit margin = (Earning before interest and tax ÷ Revenue) × 100
= $161,000 ÷ $650,000 × 100
= 24.77%
Therefore we have applied the above formula and hence option is not available.
Answer: Delegation
Explanation: Delegation in the context above may simply be explained as the process whereby there is a shift in the responsibility of one person to another who will function as a deputy. When an individual usually a superior, who is the actual overseer of a certain process or routine entrusts or handover to another person due to one reason or the other such as tight scheduling or shortage of personnel. In most cases the new handler is usually a lower ranking official in the task such as in the scenario above and as such, the expected rate of output is slightly reduced.
