"Mathematics - the unshaken Foundation of Sciences and the plentiful Fountain of Advantage to human affairs." -- (Isaac Barrow, 1630-1677)
Nicholas Copernicus (1473-1543): He rejected Ptolemy's model of an earth-centered universe. Copernicus' model, long since proved incorrect, involved 34 circles, and had the sun at the center of the universe with the earth as a "wanderer." Copernicus' ideas represented an assault on the Christian Church, which had Earth as the center of God's attention. Among other things, the Church referenced Biblical passages suggesting an immovable earth, such as Psalm 93:1, Psalm 104:5, and Ecclesiastes 1: 4-5.

ASSIGNMENT #33 Reading: Section 5.3, pages 286-296, including SUMMARY (page 296). Also, study CHAPTER REVIEW (pages 298-300) Exercises: Use your TI-83 to run twenty trials to test what happens if
Record your data and come up with an empirical probability of having an oversold situation. |
You are in Section 5.3.
What appears here is a summary of the TI-83commands that allow for a simulation of the Herky Airlines situationdescribed in the section summaries. Herky Airline planes have 40passenger seats, 90% of ticket purchasers show up for flights, andthe airline sells 43 tickets for each flight. In this simulation, 43random numbers are chosen from the set {0,1,2,3,4,5,6,7,8,9}. When a9 appears, this represents a no-show ticket purchaser. Here are theTI-83 instructions for this simulation, where -> indicates STO(Store).
