MATH 20 Final: MATH 20 Final Exam
Document Summary
Here are some problems that appeared on past math 20 exams. Note that you will be given a table of z-scores for the standard normal distribution on the test. Don"t forget to have a serious look at hw9. (1) (a) state both parts of the fundamental theorem of calculus as accurately as pos- sible. (b) consider the function de ned by h(x) := z x+1. Show using the change of variable z = (x )/ that z is normally distributed with mean 0 and standard deviation 1. (b) a radar unit is used to measure speeds of cars on a motorway. The speeds are normally distributed with a mean of 90 km/hr and a standard deviation of 10 km/hr. What is the probability that a car picked at random is travelling at more than 100 km/hr? (4) a football is thrown upward from a height of 4 feet with a velocity of 20 feet per second.
