Math Wise Season 1, Episode 11: Predicting: Choosing a Sample

0 0 • 15 min • 0.0/10

The city council wants to pass a bill that would prohibit commercial use of the marina. That would sacrifice Cynthia's sailing instructions. But just who is in favor of restricting use of the marina, and why? It takes a while for Cynthia and her friends to determine who to ask. As a result of that sample, Cynthia and her friends discover that the real impetus for the bill was that marina members were sick of an old sea dog's clunky boat. But he wants to show a council member that his boat is getting cleaned up. Watch Math Wise Season 1, Episode 11 Predicting: Choosing a Sample in HD free online.

Measuring: Measuring Instruments

A Dallas-type plot pits big-business baron Roy Singleton with a young farm family, the Nobles. For quite a while, Singleton has tried to take their property, and now he seems to have found the answer. The old deed set the property line ""five chains from the northernmost granite rock."" Singleton and his surveyors have measured, and decided that the property line should be 100 meters south. Were this to be true, the Noble family would lose their only access road. In confidence, Mr. Noble decides that, if the property line is where Singleton insists, maybe the solution would be to build another access road. Paul and Leona, the youngest of the Nobles, get a trundle wheel to accurately measure how long that road would be. But all along, Singleton is watching them–and plotting. (Concludes in next episode.)

Measuring: Formulas

The proposed road for the Noble family is too expensive to build. When Leona argues that the high price doesn't make sense, she is told that a road has three dimensions. It would take 23 dump trucks to cart off the dirt before any gravel could be laid down. None of that would prevent Roy Singleton from taking over the farm property that he thinks is his. Still, Mr. and Mrs. Noble want to see the original deed. They telephone Leona with what appears to be bad news: It's true that the boundary line was five chains south of ""the northernmost granite rock."" Given that information, Leona sets out to calculate the area of the farm. But there's something that doesn't add up–unless Roy Singleton measured from the wrong rock. Sure enough, Leona and her brother Paul scout around and, in the presence of Roy Singleton, find the northernmost granite rock.

Predicting: Probability

Micki and the Marveltones put a lot of money and effort into recording a single, hoping that a radio station will play it. But the record gets lost in a slew of submissions from local bands (this is Los Angeles, after all). After an exhaustive study, the Marveltones' only clue turns out to be the biggest arrow of all. It would be easier to get on radio if they record a slow song, because it had a greater chance of being played.
