Arollercoaster can fit a maximum of 30 people per ride. how many rides will there be if 754 people buy tickets for the rollercoaster? a. divide 754 by 30. the answer is 25 with 4 left over. so there will be 25 rides. b. divide 754 by 30. the answer is 251 with 1 left over. so there will be 252 rides. c. divide 754 by 30. the answer is 25 with 4 left over. so there will be 26 rides. d. multiply 754 by 30. the answer is 22,620. so there will be 22,620 rides.

It appears that people who are mildly obese are less active than leaner people. one study looked at the average number of minutes per day that people spend standing or walking. among mildly obese people, the mean number of minutes of daily activity (standing or walking) is approximately normally distributed with mean 376 minutes and standard deviation 64 minutes. the mean number of minutes of daily activity for lean people is approximately normally distributed with mean 528 minutes and standard deviation 107 minutes. a researcher records the minutes of activity for an srs of 7 mildly obese people and an srs of 7 lean people. use z-scores rounded to two decimal places to answer the following: what is the probability (image for it appears that people who are mildly obese are less active than leaner people. one study looked at the averag0.0001) that the mean number of minutes of daily activity of the 6 mildly obese people exceeds 420 minutes? what is the probability (image for it appears that people who are mildly obese are less active than leaner people. one study looked at the averag0.0001) that the mean number of minutes of daily activity of the 6 lean people exceeds 420 minutes?
