Your company sells exercise clothing and equipment on the internet. to design the clothing, you collect data on the physical characteristics of your different types of customers. here are the weights (in kilograms) for a sample of 24 male runners. assume that these runners can be viewed as a random sample of your potential male customers. suppose also that the standard deviation of the population is known to be sigma = 4.5 kg: what is sigma1, the standard deviation of ? 0.188 kg. 2.s78 kg. 0.919 kg. 4.s kg.

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.
