We are given an arithmetic expressionx1o1x2o2...xn−1on−1xn such thatxifor 1≤i≤narepositive numbers andoi∈{+,×}for 1≤i≤n−1 are arithmetic operations (summation ormultiplication). We would like to parenthesize the expression in a such a way that the valueof the expression is maximized. For example, if the expression is 3 + 4×2 + 6×0.5, then theoptimal parenthesization is (3 + 4)×(2 + (6×0.5)), with a value of 35.

Two angles are complementary. the large angle is 36 more than the smaller angle. what is the measure of the large angle?

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.
