Angle abd and angle dbc are linear pairs, and angle abd and angle edc are vertical angles. if the measure of angle abd=5(2x+1), the measure of angle dbc=3x+6, and the measure of angle ebc=y+135\2, select all the statements that are true a) measure of angle abd=45 b.) measure of angle dbc=135 c.) x=13 d.)y=135 e.)measure of angle edc =135 e.) measure of angle abc + the measure of angle abe=270 f.) angle dbc and angle ebc are linear pairs

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.

Evaluate the expression for the given value of the variable. | ? 4 b ? 8 | + ? ? ? 1 ? b 2 ? ? + 2 b 3 -4b-8+-1-b2+2b3 ; b = ? 2 b=-2
