This geometry video tutorial provides a basic introduction into solving ratios and proportions word problems. It explains how to calculate the arithmetic mean and geometric mean of two numbers. It helps you to understand why this process works by writing an arithmetic sequence and a geometric series. It mentions how to calculate the mean proportional of two numbers as well as how to identify the means and extremes. It contains a practice problem that helps you to calculate the number of girls in a classroom given the ratio of boys to girls. It discusses how to determine the ratio of x to y given an equation. It contains a problem that explains how to determine the ratio of the area of two squares as well as the ratio of the perimeter of two squares. There's another problem that explains how to use ratios and proportions to calculate the distance between two cities given a scale map as well as the scale factor that goes with it. The last problem discusses how to calculate the perimeter of a rectangle given the area of the rectangle with the ratio of the length to the width of the rectangle.

This site provides links to random videos hosted at YouTube, with the emphasis on random. π₯
Origins of the Idea π±
The original idea for this site stemmed from the need to benchmark the popularity of a video against the general population of YouTube videos. π§
Challenges Faced π€
Obtaining a large sample of videos was crucial for accurate ranking, but YouTube lacks a direct method to gather random video IDs.
Even searching for random strings on YouTube doesn't yield truly random results, complicating the process further. π
Creating Truly Random Links π οΈ
The YouTube API offers additional functions enabling the discovery of more random videos. Through inventive techniques and a touch of space-time manipulation, we've achieved a process yielding nearly 100% random links to YouTube videos.
About YouTube πΊ
YouTube, an American video-sharing website based in San Bruno, California, offers a diverse range of user-generated and corporate media content. π
Content and Users π΅
Users can upload, view, rate, share, and comment on videos, with content spanning video clips, music videos, live streams, and more.
While most content is uploaded by individuals, media corporations like CBS and the BBC also contribute. Unregistered users can watch videos, while registered users enjoy additional privileges such as uploading unlimited videos and adding comments.
Monetization and Impact π€
YouTube and creators earn revenue through Google AdSense, with most videos free to view. Premium channels and subscription services like YouTube Music and YouTube Premium offer ad-free streaming.
As of February 2017, over 400 hours of content were uploaded to YouTube every minute, with the site ranking as the second-most popular globally. By May 2019, this figure exceeded 500 hours per minute. π
