10. Modify your program from Programming Project 9 so that it outputs the sum of all positive numbers, the average of all positive numbers, the sum of all nonpositive numbers, the average of all nonpositive numbers, the sum of all positive and nonpositive numbers, and the average of all numbers entered. 11. Sound travels through air as a result of collisions between the molecules in the air. The temperature of the air affects the speed of the molecules, which in turn affects the speed of sound. The velocity of sound in dry air can be approximated by the formula:

velocity ≈ 331.3 + 0.61 ×Tc where Tc  is the temperature of the air in degrees Celsius and the velocity isin meters/second. Write a program that allows the user to input a starting and an ending temperature. Within this temperature range, the program should output the temperature and the corresponding velocity in 1° increments. For example, if the user entered 0 as the start temperature and 2 as the end temperature, then the program should output 

At 0 degrees Celsius the velocity of sound is 331.3 m/s At 1 degrees Celsius the velocity of sound is 331.9 m/s At 2 degrees Celsius the velocity of sound is 332.5 m/s

Write a program that calculates the total grade for N classroom exercisesas a percentage. The user should input the value for N followed by each ofthe N scores and totals. Calculate the overall percentage (sum of the totalpoints earned divided by the total points possible) and output it as a per-centage. Sample input and output is shown below.

How many exercises to input? 3

Score received for exercise 1:10

Total points possible for exercise 1:10 

Score received for exercise 2:7

Total points possible for exercise 2:12

Score received for exercise 3:5

Total points possible for exercise 3:8

Your total is 22 out of 30, or 73.33%

CSIS Discussion

NEED THIS BY 11PM EASTERN TONIGHT!!!

Instructions:
 

*First, Discuss topic in at least 250 word paragraph.
 

*Second, make 1 reply of at least 100 words for each  paragraph provided below. For your paragraph and replies, you  should   support your assertions with at least 1 source and accompanying   citations in APA format. Acceptable sources include the textbook,   reputable websites, and the Bible.

Discussion Topic:
 

A user complains that her computer is responding very slowly. She also  says that when booting the PC, it reports a lower value for memory than  she assumed is available. You investigate and consider the idea that one of the RAM sticks in her PC may have become unseated. Detail the steps  you would take to determine how to diagnose and reset the RAM.
 

100 word Reply to Each Paragraph!
 

Paragraph #1
 

    DB 3 RAM issues         

Random  Access Memory (RAM) is “one of the most important components of not  only desktop PCs, but laptops, tablets, smartphones, and gaming  consoles. Without it, doing just about anything on any system would be  much, much slower”. (Martindale, 2019, p.1) Ram is where a computer  temporarily stores information that will need access for a short time.  When troubleshooting a RAM issue, the first thing I would do is to check  the BIOS to make sure that the correct amount of memory it says it  installed. Not having the recommended amount of RAM installed may be a  problem and you may have to consider upgrading. Next, locate the RAM  sticks making sure the computer is completely powered down, opening the  case by removing the side or back panel. Next press down on the  retention clips on both ends of the motherboard slots to remove the RAM  sticks. Install the new RAM making sure RAM sticks are aligned correctly  within the space of the motherboard slots. “Be sure to note the  location on the notches on both the RAM Nd the DIMM slots”. (Techanew,  n.d.). When the Ram sticks are installed correctly, they will click into  place. Close the computer by putting the panels back on and restarting  the computer to test and see if the issue has been resolved.

Paragraph 2
 

   When  determining how to diagnose and reseat the RAM I would begin by  checking the amount of RAM on the computer. “A system that does not have  enough RAM can sometimes appear to be unstable. Using the systems  window, find out how much RAM is installed, and compare recommended  amounts. Consider upgrading RAM” (Andrews, Dark, & West, 2017).  After checking and making sure the correct amount of RAM is installed, I  would then begin by checking the RAM sticks. I would first turn the  computer off and I would then open the case and release the clips  holding in the RAM sticks. I would then remove each RAM stick  and reseat each RAM stick ensuring clips are fully engaged.  After reseating all the RAM sticks, I would then reboot the computer to  see if it responds and begins to work correctly. If it is still not  working, I would shut down the computer again and remove each RAM stick.  I would insert only one of the RAM sticks and turn on the computer to  see if the RAM stick is working properly. I would repeat this process  for each RAM stick until a bad RAM stick is found. If no bad RAM sticks  are found, then I would turn off the computer and insert a known good  RAM stick into one of the RAM slots on the motherboard. I would then  turn on the computer to see if it is working properly. I would repeat  for each slot on the motherboard until a bad slot is found.

Software Development History Presentation (6-8) slides

/in /by

Assignment Instructions

Create a narrated 6-8 slide presentation in Microsoft PowerPoint® in which you discuss the aspect of software development history that you found most interesting during this week’s learning. Be sure to discuss whether this historical aspect has a continuing influence in today’s software development environment in terms of core programming concepts such as repetition structures, decision structures, arrays, functions, and variables. For example, think about how the shift from procedural programming to object-oriented programming changed or did not change how the core concepts were handled. When composing your presentation, be sure to use Standard English and a highly developed and sustained viewpoint and purpose. The communication of your presentation should be highly ordered, logical and unified.

Additionally, one slide must be devoted to some aspect of software development history demonstrating the benefits of multiculturalism and diversity in a global context. How has software development evolved as we have become more globalized and how has it influenced the growth and change in software development?

Your presentation must have narration throughout as if you were delivering it in a live, professional setting. Focus on your word choice. Your oral delivery techniques, including word choice and oral expressiveness, should display exceptional content, organization, and style, while leading the audience to a dynamic and supported conclusion.

For instructions on adding audio to your presentation, please review the HOONUIT module on adding media.

Stretch Assignment: (I’d like to include this portion of the assignment in future classes. I ask that you give it a try and provide me a short summary on your thoughts of adding this to the class going forward!)

Macros are little recorded sessions of code changes in Excel. We know scripting as anything trigger or event based that is recurrent. I ask that you create a script in Excel by creating a Macro. Your macro should ZERO OUT all of the data in the table you are using. You can call the macro, StartOfTheDay. You would run this macro, say, when you arrived in the morning to enter new data into the tables and purge the data from the previous day. Give it a try! Remember save your file as a filename.xlsm (if it includes a macro). If you’d prefer a different macro, just let me know the pupose of your macro in the comments section of your submission.

Week 8 Discussion – Adding New Resources to Your Project

/in /by

In order to deliver the Home Office Renovation project ahead of schedule, you have been granted permission to add more resources to your team. Your project sponsor has worked out a deal to add an outside firm (partner) to your project team. They have very little understanding of your project, and you don’t have a lot of time to educate them on the project’s specifics. Describe how you plan to incorporate them as members of your project, as well as how to get them up to speed on your project for Home Office Renovation.
