A model rocket is launched from the deck in Jim's backyard and the path followed by the
rocket can be modeled by the relation h = -5t^2 + 100t + 15, where h, in metres, is
the
height that the model rocket reaches after t seconds.
a) What is the height of the deck?
b) What is the height of the model rocket after 2 s?
c) What is the maximum height reached by the model rocket?
formula:
x=
-b ± √b² - 4ac
2a

Cor d? ? 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.
