During a recent eruption, a piece of ash was ejected from a volcano with an initial velocity of 368 ft/sec. the height (h), in feet, of our ash projectile is given by the equation h=16t^2 + 368t where t is time, in seconds. the graph of the equation will be a parabola assume the volcano does not have a height. so, h= 0 and t=0 1.) when does the ash projectile reach it's maximum height? 2.)what is the maximum height? 3.)when does the ash projectile return to the ground?

Me max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.
