30. A fence surrounds a square plot of land. The area of the land is 324 yd2. Find the length of each side
of the fence.
Use the strategy Systematic Guess and Check.
• 10 x 10 = ? The initial guess is (correct, high, low).
• 20 x 20 = ?This guess is (correct, high, low).
? X ?= 324 This guess is correct.

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.

Find the volume of the solid whose base is the region bounded by f(x), g(x) and the x-axis on the interval [0, 1], and whose cross-sections perpendicular to the y-axis are squares. your work must show the integral, but you may use your calculator to evaluate it. give 3 decimal places for your answe
