Answer:
Following are the response to the given question:
Explanation:
The glamorous objective is to examine the items (as being the most valuable and "cheapest" items are chosen) while no item is selectable - in other words, the loading can be reached.
Assume that such a strategy also isn't optimum, this is that there is the set of items not including one of the selfish strategy items (say, i-th item), but instead a heavy, less valuable item j, with j > i and is optimal.
As  , the i-th item may be substituted by the j-th item, as well as the overall load is still sustainable. Moreover, because
, the i-th item may be substituted by the j-th item, as well as the overall load is still sustainable. Moreover, because  and this strategy is better, our total profit has dropped. Contradiction.
 and this strategy is better, our total profit has dropped. Contradiction.
 
        
             
        
        
        
Answer:
Boolean
Explanation:
Boolean is one of the primitive data types that will only hold either true or false value. This data type is commonly used in a variable that will track a status with only two possible outcomes. 
For example, the<em> ParticipantPD</em> field is to track the payment status (paid or unpaid) of a participant. So, declare the<em> ParticipantPD</em> field as boolean data type will meet its purpose.
                boolean ParticipantPD = true;
                or
                boolean ParticipantPD = false;

HLOOKUP performs the same function as VLOOKUP, but looks up data that has been formatted by rows. HLOOKUP searches for a value in the top row of a table, and then returns a value in the same column from a row you specify in the table or array
 
        
                    
             
        
        
        
Answer:
Demilitarized zone (DMZ).
Explanation:
Demilitarized zone is a kind of security assurance scheme used by network administrator to detect network breach even before it gets to the secured network. 
The private LAN is protected with a firewall and a DMZ is configured to allow access by untrusted users, on another workstation, which is a duplicate of the companies private local address.
