Answer:
The design model is the description of the model to be implemented, the analysis model is the model that links the design and the system or domain model while the domain model is the entire software implementation.
Explanation:
The domain model is the conceptual aspect of software engineering that comprises operational and data features. The analysis model is the schematic description of the system that links the design model to the system domain. The design model is also known as the object model as it shows an abstract representation of the implementation. It helps to test the quality of the software been developed.

Answer:
The flashdrive can hold 35389 400-pages-books
Explanation:
If
of a page occupies 1 kB of memory, we can calculate how much memory a book will take

Now that we know that a book average file size is about 266,67 kB, we calculate how many of them can a 9 GB flash drive hold.
To do the calculation, we have to know how many kilobytes are in 9 gigabytes.
There is 1024 kilobytes in a megabyte, and 1024 megabytes in a gigabyte, so:

Finally, knowing the average file size of a book and how much memory in kilobytes the 9 GB flash drive holds, we calculate how many books can it hold.

The flashdrive can hold 35389 400-pages-books, or 14155776 pages of typical text.

Answer:
See explaination for the code
Explanation:
def wordsOfFrequency(words, freq):
d = {}
res = []
for i in range(len(words)):
if(words[i].lower() in d):
d[words[i].lower()] = d[words[i].lower()] + 1
else:
d[words[i].lower()] = 1
for word in words:
if d[word.lower()]==freq:
res.append(word)
return res
Note:
First a dictionary is created to keep the count of the lowercase form of each word.
Then, using another for loop, each word count is matched with the freq, if it matches, the word is appended to the result list res.
Finally the res list is appended.
