Explanation / Answer

5. The answer is option 2. Given a table of net profit per item, choose the cutoff value that maximizes net profit.

Any business ultimate motto is to grow with business by earning profits, its true that they expect no losses at the least preference, but they are happy to take a path on cocentrating on items that generate profits by analysing the profitability of particular items.

So the answer is option 2.

6. The answer is option 2. 0.978

The total accuracy of a system is calculated by number of success/Total expected attempts.

As the number of attempts is sum of total number of success + total number of failures.

Total attempts = 8+2+20+970

Total successes = 8 +970

Where r in actual 1 case and 970 in actual 2 case.

So total accuracy of rhe system is 978/1000

= 0.978

The answer is option 2. 0.978

7) please refer the question 6. It is showed in steps clearly.
