If triangle MNO is rotated 180 degrees clock wise about the Irgun to form triangle PQR , what are the coordinates of the verticals of Triangle PQR? What conjecture can be made about the relationship between the coordinates of the vertices of a shape rotated 180 degrees clockwise about the origin and original shape ? explain your reasoning

Apsychology student wishes to investigate differences in political opinions between business majors and political science majors at her college. she randomly selects 100 students from the 260 business majors and 100 students from the 180 political science majors. does this sampling plan result in a simple random sample? why or why not? no, because each group of 200 students in the sample does not have the same chance of being selected. yes, because each group of 200 students in the sample has the same chance of being selected. no, because each individual student does not have an equal chance of being selected. yes, because each individual student has the same chance of being selected.
