Answer:
See explaination
Explanation:
Please check below for the code for first_word.py file which will print first word of an input file stuff.txt. So the open function will open file in read mode. We had maintained a count variable so that we can skip printing first word of first line. Also the command line.strip() checks whether string is empty or not so that we will not get index error while calling split function over line to get first word.
#!/usr/local/bin/python
stuff = open("stuff.txt", "r");
count = 0;
for line in stuff:
count+=1;
if (count>1 and line.strip()):
print(line.split(maxsplit=1)[0])
Answer: So have you done assignment 5? and have you read back the previous one?
Answer: Stratified sample
Explanation:
For preparing samples of various data of companies and enterprises we need to apply probability distribution to different samples of data. Here in the question we are to apply a representative sample from a list of 200 customers who have complained about errors in their statement. So here we can apply stratified sampling where we can divide the 200 customers into separate groups. These sub groups of the customers are known as stratas. These stratas are selected based on certain characteristics which can be identified among the customers group. Here we can form subgroups based on the type of complain that has been lodged by the customer and selecting 5 customers from four zip codes. Then it would be easy to apply probability distribution to the sub groups to derive information from them.
This process would also enable a more easier and cheaper way of sampling the customer data.
Answer:
In order to start engineering you must know the basics Science, Math, and Technology. For example you need math to get all the parts in the right place and fix any pieces that need to be angled right, science because you need to know what happens if you put this with that if it’ll spark break or anything, and technology because you need to know the different pieces and their purpose, hope it helps!
Explanation:
Since Joan wants to see what her presentation would look like in the eyes of her audience, it might be best for her to use the Slideshow view that is available at the bottom right side of her desktop view.
This option is a full-screen form of her Normal view in Microsoft PowerPoint. The Slideshow view is represented by the projector screen symbol next to the zoom in and out bar.
