Answer:
The correct answer is controlled maintenance. 
Explanation:
It is the maintenance whose mission is to maintain a certain level of service in the equipment, programming the interventions of their vulnerable points at the most appropriate time. It usually has a systematic character, that is, it intervenes even if the team has not given any symptoms of having a problem.
Some data transmission networks mess up the messages they send, so if the messages are sent in a certain sequence, they are not guaranteed to arrive in that same sequence. To solve this, the protocol must incorporate a mechanism that allows it to reorder the messages at the destination. This mechanism can be the numbering of the fragments, for example.
 
        
                    
             
        
        
        
We
should note that the bond investment account is recorded at cost by the Bondholder
or Investor. 
The
cost or price is calculated as:
Cost
= $90,000 * 86.4%
Cost
= $90,000 * 0.864 = $77,760
Therefore,
the entry to record should be:
<span>debit
Held-to-Maturity Investment in Bonds for $77,760 and credit Cash for $77,760</span>
 
        
             
        
        
        
Answer:
The correct answer is: Typically, some resources are better suited for producing one good than another, which means that there are diminishing returns when moving such resources away from producing what they are best suited for. 
Explanation:
A production possibility curve shows the different combinations of two goods that can be produced using all the given resources. Since resources are scarce, to increase the production of one good we need to decrease production of the other.  
But resources are specialized and cannot be perfectly substituted between their two uses. So as we go on increasing production of one good the opportunity cost of sacrificing its alternative goes on increasing.
Because of this increasing opportunity cost the shape of the frontier is downward sloping, bent outwards and concave to the origin.
