May has 31 days. how would the experimental probability be affected if someone mistakenly used 30 days to calculate the experimental probability that the maximum temperature will not be greater than 90ºf on a given day in may? (hint: select the correct reason with the correct calculation.)
answer choices:
20/31 is greater than 19/30 so using fewer days in the month produces a smaller probability
19/31 is greater than 19/30 so using fewer days in the month produces a smaller probability
20/31 is greater than 19/30 so using fewer days in the month produces a greater probability
19/30 is greater than 20/31 so using fewer days in the month produces a greater probability

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 \piπpi, what is the mass of sand indiana jones needs to avoid triggering the mechanism?
