The Golden Gate Bridge in San Francisco, is a suspension bridge. It is supported by a pair of cables that are parabolic in appearance. The cables are attached at either end to a pair of towers at points 152 m above the roadway. the towers are 1,280m apart and the cable reached its lowerst point when it is 4m above the roadway. Determine an algebraic expression that models the cable as it hangs between the towers. Transfer the data to a graph where the parabola lies below the x axis. Use the centre between the two towers as the y-axis...thanks..email me the graph if you can at madaubin@yahoo.ca..thanks for all your help.

Ok you are an expert on the concept of Infinity. One night very late, you check into the Infinity Hotel, which happens to have an infinite number of rooms.

But the desk clerk tells you that even though they have an infinite number of rooms, there are an infinite number of people staying there that evening, and only one person is allowed in a room at a time. You, being an infinity expert, come up with a simple way to get a room for the night. How do you do it? (no, you don't go in a room and kill somebody and throw the body out or something like that)

Statistics is a mathematical science pertaining to collection, analysis, interpretation, and presentation of data as well as drawing valid conclusions and making reasonable decisions on the basis of such analysis.

In a narrower sense the term is used to denote the data themselves or numbers derived from data as, for example, averages. Thus we speak of employment statistics, accident statistics, etc.

It is applicable to a wide variety of academic disciplines from the physical and social sciences to the humanities, as well as to business, government, medicine and industry.

Statistical methods can be used to summarize or describe a collection of data; this is called descriptive statistics. In addition, patterns in the data may be modeled in a way that accounts for randomness and uncertainty in the observations, to draw inferences about the process or population being studied; this is called inferential statistics. Both descriptive and inferential statistics can be considered part of applied statistics. The discipline of mathematical statistics is concerned with the theoretical basis of the subject. The word statistics is also the plural of statistic (singular), which refers to the result of applying a statistical algorithm to a set of data.
