the coordinates of the vertices of quadrilateral jklm are j(−3, 2) , k(3, 5) , l(9, −1) , and m(2, −3) .

which statement correctly describes whether quadrilateral jklm is a rhombus?

a) quadrilateral jklm is not a rhombus because there are no pairs of parallel sides.

b) quadrilateral jklm is a rhombus because opposite sides are parallel and all four sides have the same length.

c) quadrilateral jklm is not a rhombus because opposite sides are parallel but the four sides do not all have the same length.

d) quadrilateral jklm is not a rhombus because there is only one pair of opposite sides that are parallel.

Consider the reaction 2x2y2+z2⇌2x2y2z which has a rate law of rate= k[x2y2][z2] select a possible mechanism for the reaction.

In a study of the relationship between socio-economic class and unethical behavior, 129 university of california undergraduates at berkeley were asked to identify themselves as having low or high social-class by comparing themselves to others with the most (least) money, most (least) education, and most (least) respected jobs. they were also presented with a jar of individually wrapped candies and informed that the candies were for children in a nearby laboratory, but that they could take some if they wanted. after completing some unrelated tasks, participants reported the number of candies they had taken. it was found that those who were identiď¬ed as upper-class took more candy than others. in this study, identify: (a) the cases, (b) the variables and their types, (c) the main research question, (d) identify the population of interest and the sample in this study, and (e) comment on whether or not the results of the study can be generalized to the population, and if the ď¬ndings of the study can be used to establish causal relationships.
