The following table shows the number of hours some high school students in two states spend surfing the internet each week: state a 35 36 35 34 35 38 36 36 38 state b 24 22 20 50 25 24 65 25 26 part a: create a five-number summary and calculate the interquartile range for the two sets of data. (6 points) part b: are the box plots symmetric? justify your answer. (4 points)

Given: abcd is a square. prove: ac ? bd. we are given that abcd is a square. if we consider triangle aeb and triangle aed, we see that side is congruent to side ad because sides of a square are congruent. we know that side ae is congruent to side ae by using the . finally, we know that side de is congruent to side because the diagonals of a square bisect each other. therefore, triangle aeb is congruent to triangle aed by congruency. we see that angle aed and angle aeb are a linear pair, and congruent by cpctc. thus, the measure of these angles will be 90°, and diagonal ac is perpendicular to diagonal bd by the .
