The vectors e1 = are called the elementary vectors in r2. (a) find all solutions c1, c2 such that ciei + c2e2 = 0. (b) show that any point (i. e. vector), (2, y), in r2 can be written as a linear combination of ej and e2-in a rather obvious way. question 2. now consider the vectors u1 = ( 1 and us = [ -1 ]: (a) find all solutions c1, c, such that cu + cu2 = 0. (b) show that any point (i. e. vector), (x, y), in r2 can be written as a linear combination of u and u.

Which one is true about the hexagons ?

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.
