Kathy ordered a 14 inches pizza. When she came to the store to pick up her pizza. The
owner told her "I can give you a discount if you can answer my question". Kathy said
"Sure!" The question is "What is the area of one slice of this pizza if I cut it into 8 slices.
Tell me your answer in terms of t." Can you help Kathy with the answer for this question?

There are two major tests of readiness for college: the act and the sat. act scores are reported on a scale from 1 to 36. the distribution of act scores in recent years has been roughly normal with mean µ = 20.9 and standard deviation s = 4.8. sat scores are reported on a scale from 400 to 1600. sat scores have been roughly normal with mean µ = 1026 and standard deviation s = 209. reports on a student's act or sat usually give the percentile as well as the actual score. the percentile is just the cumulative proportion stated as a percent: the percent of all scores that were lower than this one. tanya scores 1260 on the sat. what is her percentile (± 1)?
