Engineers want to design seats in commercial aircraft so that they are wide enough to fit 99% of all males. (accommodating 100% of males would require very wide seats that would be much too expensive.) men have hip breadths that are normally distributed with a mean of 14.5 in. and a standard deviation of 1.1 in. find upper p 99. that is, find the hip breadth for men that separates the smallest 99% from the largest 1%.
the hip breadth for men that separates the smallest 99% from the largest 1% is upper p(99)=

Ascientist places 24 cells in a petri dish. she knows the cells grow at an exponential rate, doubling in number every hour. how long will it take (in hours) for there to be 1100 cells in the dish? time to 1100 cells: 5.51832530 hours how long will it take to reach 110 cells? time to 110 cells : 2.1963972 hours what is the average rate of change in the number of cells between 9 hours and 11 hours? average rate of change: cells per hour what is the instantaneous rate of change after 7 hours? instantaneous rate of change: cells per hour note: you can earn partial credit on this problem.
