The general form of the equation of a circle is Ax2 + By2 + Cx + Dy + E = 0, where A = B 0. If the circle has a radius of 3 units and the center lies on the y-axis, which set of values of A, B, C, D, and E might correspond to the circle? A.
A = 0, B = 0, C = 2, D = 2, and E = 3
B.
A = 1, B = 1, C = 8, D = 0, and E = 9
C.
A = 1, B = 1, C = 0, D = -8, and E = 7
D.
A = 1, B = 1, C = -8, D = 0, and E = 0
E.
A = 1, B = 1, C = 8, D = 8, and E = 3

Suppose i flip two identical coins. what is the probability that i get one head and one tail?

Ihonestly have no clue if it's each or none.

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.
