jill has a swimming pool in her backyard. it is shaped like a rectangle and measures approximately 16.3 feet wide and 26.2 feet long. it is an average of 5 feet deep. during a few hot weeks during the summer, some water evaporates from the pool, and jill needs to add 8 inches of water to the depth of the pool, using her garden hose. although her water pressure varies, the water flows through jill’s garden hose at an average rate of 10 gallons/minute.
how many liters will jill need to add to her pool to return the water level to its original depth? how many gallons of water is this? reminder: volume = length x width x depth

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?
