Danisha found the volume of the figure shown. her work is shown below.
analyze danisha’s work for finding the volume of the composite figure. what was her mistake?
a) she should have found the volume for a cone instead of the volume of a sphere.
b) she used the wrong formula for the volume of the cylinder.
c) she did not halve the volume of the sphere to find the volume for the half sphere.
d) she needed to find the product of the volumes instead of the sum.

Now 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.

Segment an is an altitude of right δabc with a right angle at a. if ab = 2, squared 5 in and nc = 1 in, find bn, an, ac.

Amass weighing 16 pounds stretches a spring 8/3 feet. the mass is initially released from rest from a point 2 feet below the equilibrium position, and the subsequent motion takes place in a medium that offers a damping force that is numerically equal to 1/2 the instantaneous velocity. find the equation of motion if the mass is driven by an external force equal to f(t)=cos(2t).
