A mapping company is creating a program that can predict the traffic on routes and estimate the delay from the traffic. The program takes an input of 5 routes and outputs the delay for each route. The program has two phases: Setup: Loads historical traffic data for the geographic region. Simulation: Predicts the traffic and estimates the delay of 5 routes. The initial setup phase takes 10 minutes. The simulation phase takes 5 minutes per route, which amounts to 25 minutes total for the 5 routes. The program takes 35 minutes total. The company would like to improve the program's efficiency by parallelizing the simulation operations. What is true about the potential efficiency gains

Answer (b) the meter will display a negative sign;

The answer is the third one (organizational chart)

The main part about version control is that you have a repository, which hosts files. any changes done to those files are recorded and, as such, can be reverted back. it is kind of like google drive/google docs (except not as "real-time autosave"). usually these files involve code. version control can usually record changes to files and the lines of code themselves.version control is used by developers, mainly with coding. this may include websites, software, video games, etc. it is very useful in terms of practicality and collaboration.  reverting back a previous version of a file is very useful in the coding/programming world. suppose a programmer adds in something new to a file, a code snippet or two. then he changes his mind because he does not like the feature he coded in (it does not work, inefficient, with version control, he can easily revert back the changes he made.  version control also makes it easier to collaborate. oftentimes, you can use an online, remote  repository such as github or bitbucket. a team of people  can each  connect their computers  to this repository and be synchronised with the source code.recording your changes is also for teamwork  as it tells you who did what. changes can be monitored as well.  online repositories (like  github) may also contain  features to talk about issues with the code, and you can  reference them in the changes.version control also allows you to have different versions of the same thing. there are open source projects where anyone able can contribute to the project; such collaborators are able to create a new version (a new "branch") from the master branch. in this new branch derived from the main master branch, one adds their code and such.  in time, the original developer will look at this branch; they can add all or some of those changes to the main branch if they approve.
