No-cfc and green cool manufacture air conditioners. no-cfc claims that their air conditioners cool faster than green cool air conditioners. an air conditioning magazine decided to test no-cfc's claim. they randomly tested five no-cfc air conditioners at their dallas office and five green cool air conditioners at their phoenix office. all of the air conditioners had the same specifications, were set to auto cooling mode, and were installed in rooms with the same amount of space to be cooled. after observing the cooling effect of each air conditioner, the magazine reported that the average time it takes for a no-cfc air conditioner to reduce the room temperature by 3Β°f was 10 minutes, and the average time it takes for a green cool air conditioner to reduce the room temperature by 3Β°f was 12 minutes. given the magazine's data collection method and report, what conclusion can be made?

Nthe opening scene of the movie raiders of the lost ark, indiana jones replaces a golden statue with a bag of sand. the platform on which the statue is placed is designed to detect the mass of the statue. if the bag of sand has a different mass than the statue, then a mechanism triggers and destruction ensues. the density of gold is about 20\text{ g/cm}^320 g/cm 3 20, space, g, slash, c, m, start superscript, 3, end superscript. the density of sand can be estimated at 2.5\text{ g/cm}^32.5 g/cm 3 2, point, 5, space, g, slash, c, m, start superscript, 3, end superscript. the gold statue can be modeled as a cylinder with height 25\text{ cm}25 cm25, space, c, m and radius 8\text{ cm}8 cm8, space, c, m. in terms of \piΟpi, what is the mass of sand indiana jones needs to avoid triggering the mechanism?
