Using python: In the directory rootdir some of the files contain randomly generated content while others are written by human authors. Determine how many of the files contained in the directory are written by human authors. Store your answer in the variable number_human_authored.

Using repl.it, your own Linux installation, or other Linux emulator do the following and take screenshots for the steps that require it. Paste your screenshots into a word document, in the same order as the questions, and upload the file by 11 AM on Friday.

1. Show the contents of your home directory and take a screenshot

2. Create a directory named IT305 in your home directory and take a screenshot

3. Create a file called oldfile.txt in your home directory using the command line method of your choice. Make sure the file has at least 10 lines of characters in it. (I would suggest writing 10 lines that follow a pattern like this - This is line 1. This is line 2. and so on)

4. Create a new file in IT305 in the following manner:

use the nl command to number the lines of oldfile.txt, pipe that to the head command but only show the first 5 lines, pipe that to the tail command but only show 2 lines and redirect that output to the IT305 folder and create the newfile.txt. Do this on one command line. Take a screenshot of the command line that you use and of the contents of newfile.txt

5. Using the nslookup command, do a lookup of www.marymount.edu  (Links to an external site.)and redirect the output to a file named marymount.txt

6. del the IT305 directory and take a screenshot that shows that it is no longer in your home directory

Cruise Company produces a part that is used in the manufacture of one of its products. The unit manufacturing costs of this part, assuming a production level of 6,000 units, are as follows: Direct materials $4.00 Direct labour $4.00 Variable manufacturing overhead $3.00 Fixed manufacturing overhead $4.00 Total cost $15.00 The fixed overhead costs are unavoidable. 6. Assuming Cruise Company can purchase 6,000 units of the part from Suri Company for $13 each, and the facilities currently used to make the part could be rented out to another manufacturer for $24,000 a year, what should Cruise Company do? a. Make the part and save $6.00 per unit. b. Make the part and save $2.00 per unit. c. Buy the part and save $2.00 per unit. d. Buy the part and save $4.00 per unit.

You are an analyst working for the life cycle manager of a particular type of cruise missile. Periodically, the inventory of cruise missile engines must be certified and part of the certification requires testing a sample of missile engines then calculating a confidence interval for the true mean flight speed (μ in mph). Based on prior tests, it is appropriate to assume that the missile’s flight speed is normally distributed with known standard deviation, σ=20 mph.

Twenty-five cruise missiles are tested on a range with an average flight speed of?1=375 mph. You are tasked to calculate a 90 percent confidence interval for ?.

Fill in the table to help document your work:

You are the CEO of a vacation cruise company that provides cruise service between Seattle WA to Anchorage AK. To provide this service, you use two inputs: ships and attendants. The table below describes the combinations of inputs required to produce cruises service. Assume that a ship costs $1 million dollars and that each attendant costs $1,000. The ship can make multiple cruises (and note that currently, your company owns only one ship).

Fill in the remaining columns.

This is per cruise ATC and MC:

In this module, you have reviewed acoustic and radio sensors. Although they are both passive sensors, they function very differently. Given what you have learned about these sensor types, identify the strengths, weaknesses, and several example applications for both. Which do you think has the most potential for early UAS commercial operations in America and why? Can you identify any needs for additional development to make these sensors more viable for widespread integration with UAS, particularly small platforms? Be sure to consider issues related to noise, interference, effective range, etc.

1. Archway Adventures has compiled data for 2017 on customer orders by region and product group as follows:

Let us assume that these are representative of the pattern of orders that they anticipate seeing in 2018.

1. What is the probability that a randomly selected order will be from North America?
2. What is the probability that an order is from North America and it is for a game?
3. What is the probability that an order is from outside North America and Europe or is for something other than a toy or game?
4. Among orders from the “rest of the World”, what is the probability it is for a toy?
5. Among orders for toys, what is the probability that the order comes from the “Rest of the World”?
6. Are the events “Toy” and “Rest of the World” independent? Explain.
7. The rows of the table are mutually exclusive categories. How would our summary be complicated if some orders were for multiple products?

2. 54.5% of Archway’s orders come from North America, 31.5% from Europe and the remaining 14% from the rest of the world. Among North American customers, 3% complained about late or lost deliveries. Similarly, complaints were received from 8% of European customers and 15% of customers from the rest of the world.

1. Construct a probability tree that shows all combinations of where orders originated and whether customers complained. Label all branches in terms of what the event is on the branch and the corresponding probability (e.g., P(A), PA’), P(B|A), P(B’|A),…). Also determine the probability for each ending joint event (e.g., P(Europe and Complain)).
2. Summarize all of the joint probabilities in a probability table.
3. What percentage of Archway customers complained about delivery problems?
4. Among those who complained, what percentage were from Europe?

PROMPTS:

Many opponents of free trade use the following example to illustrate its negative effects: Joe Smith started the day early having set his alarm clock (MADE IN JAPAN) for 6AM. While his coffeepot (MADE IN CHINA) was perking, he shaved with his electric razor (MADE IN HONG KONG). He put on a dress shirt (MADE IN SRI LANKA), designer jeans (MADE IN SINGAPORE) and tennis shoes (MADE IN KOREA). After cooking his breakfast in his new electric skillet (MADE IN INDIA) he sat down with his calculator (MADE IN MEXICO) to see how much he could spend today. After setting his watch (MADE IN TAIWAN) to the radio (MADE IN INDIA) he got in his car (MADE IN GERMANY) filled it with gas from SAUDI ARABIA and continued his search for a good paying AMERICAN JOB. At the end of yet another discouraging and fruitless day he checked email on his computer (MADE IN MALAYSIA) then decided to relax for a while. He put on his sandals (MADE IN BRAZIL) poured himself a glass of wine (MADE IN FRANCE) and turned on his TV (MADE IN INDONESIA), and then wondered WHY he can’t find a good-paying job in America.

QUESTION: Should America encourage free trade with its trading partners or seek a more protectionist approach? Take a stand on this issue. It is not enough to argue BOTH sides of the issue. Support your opinion with good economic reasoning. Who benefits from your approach and who loses? Why? Include impacts on both American citizens and the citizens of the other countries with whom we (U.S.) trade. If your home country is outside the U.S. indicate the possible impact of your stand (favoring either free trade or trade protectionism) on your country. Some common search topics include employment, tariffs, quotas, and free trade agreements. Find a recent news article or editorial (past 12 months) that supports your point of view. Summarize the article, indicate how it supports your answer to #1, and include the URL.

EDIT:::::::: Can someone please help me out by explaining the prompt?

thanks in advance, Chegg friends.
