The social studies teacher wants to know whether the students in the entire school
prefer a model United Nations activity or a student government activity. The teacher
draws a random sample from the following groups:
• All teachers in the school
• All boys in each grade
• All students in each grade
• All students in the social studies club
Which group best represents the population he should take a random sample from
to get the best results for his survey? (5 points)
1) All teachers in the school
2) All boys in each grade
3) All students in each grade
4) All students in the social studies club

I've been working on this for a few days and i just don't understand, it's due in a few hours. you.the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α.part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part bsuppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i.e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case.part cnow try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
