An image of a parabolic lens is projected onto
and 9. Which equation models the function?
y-intercept of the graph is (0, 90), and the zeros are 5
y = 90(x - 5)(x – 9)
© y = 2(x - 5)(x – 9)
y = 90(x + 5)(x + 9)
y = 2(x + 5)(x + 9)

Needmax 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.

Prism m and pyramid n have the same base area and the same height. cylinder p and prism q have the same height and the same base perimeter. cone z has the same base area as cylinder y, but its height is three times the height of cylinder y. the figures and have the same volume.
