"With the help of God, and with His precious assistance, I say that algebra is a scientific art" -- (Omar Khayyam, 1048-1131) Fibonacci (Leonardo of Pisa, 1170-1250): While he is famous for his sequence 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, ... Fibonacci also made a major contribution to mathematics by advocating for the acceptance of the decimal system in the western world. Born in Italy, he studied under Islamic teachers during a period of his life when he lived in North Africa. He saw the advantage of the decimal system over the cumbersome systems used in Europe. He wrote many mathematical manuscripts that made use of the decimal system. Interestingly, he signed his works "Blockhead." Where did Herkimer expect to find landscaping companies in the Middle East? Answer:In Soddy Arabia. Herky's friends: CAROL LING...she loves to sing Christmas songs. SID DOWN...this guy never liked to stand around for long periods of time. ASSIGNMENT #28 Reading: Review chapter 4, as necessary. Exercises: Quizzes 4.1A, 4.1B, 4.2A, 4.2B, 4.3A, 4.3B

You are working with review materials for Chapter4.

In your collection of spreadsheets, you have onetitled SIMPSON'S PARADOX. I suggest taking a few minutes to look atthis piece of software.

A reminder that if you see a prediction model ofthe form log[y(hat)] = a + bx, this model represents an exponentialfunction.

log[y(hat)] = a + bx ==> y(hat) =10a+bx =10a10bx = 10a(10b)x.

Since 10a and 10b are constants (call then cand d, respectively), we have the form y(hat) = cdx, which represents anexponential function.
