Find an equation in standard form for the ellipse with the vertical major axis of length 18 and minor axis of length 10. X squared divided by nine plus y squared divided by five = 1 x squared divided by five plus y squared divided by nine = 1 x squared divided by twenty five plus y squared divided by eighty one = 1 x squared divided by eighty one plus y squared divided by twenty five = 1

Which is the equation of a line perpendicular to the line with the equation 3x+4y=8

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.
