In python:
first_grade = float(input("Please input the first grade "))
second_grade = float(input("Please input the second grade "))
third_grade = float(input("Please input the third grade "))
print("The average of the three grades is {}".format( round((first_grade + second_grade + third_grade) / 3,2)))
Answer:
1. Insert a table
2. Setting margins
3. Spelling and grammar correction
4. Header and footer
5. Search a word
Explanation:
1) A table can be inserted in a word document to manage data easily and in a more presentable way.
2) Different margins can be set according to the requirement and rulers can be made visible and invisible.
3) If by chance typo errors happen, a red wavy line indicates spelling mistakes and green indicates grammar mistakes which can be corrected easily.
4) Sometimes writing some professional documents, we need some text to be visible either on top or bottom of every page of that document which can be done with the help of headers and footers.
5) By pressing Ctrl+f we can easily search for a particular word in a document.
Answer:
The computer can do 12000 searches per second. Suppose there are 60000 inventory items. And we need to search one item from it in a sequential manner. The computer can do 12000 searches in one second. Hence it can search in a list of 60000 inventory in 5 seconds, as 12000 x 5 =60000 searches, in the worst case. And if the item is below 12000 on the list, it will take less than 1 second(1/12000 sec in best case), and so on.
And if we assume that the list is sorted, and perform a binary search. then in the worst case, the number of searches required in the worst case will be 60000/2= 30000. And the time required will be 30000/12000= 5/2=2.5 seconds, and (1/24000) seconds in the best case. Its 1/24000 as its binary search.
