Based on the data collected from 23 flights, what is the probability of at least one O-ring failing, regardless of temperature? (Note: This probability is called an experimental probability because it's based on only 23 flights, which is a fairly small number of events. To get a
better approximation of the actual probability, we would need data from many more flights. Note also that even though there was O-ring failure
on seven flights, all of those shuttles returned safely.)

Which expression is equivalent to -12(3x-3/4)

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?

Is ofat (-25, 0), (25, 0) co- (0, -15), (0, 15)?
