Parking at a large university has become a very big problem. University administrators are interested in determining the average parking time (e. g. the time it takes a student to find a parking spot) of its students. An administrator inconspicuously followed 300 students and carefully recorded their parking times. Identify the population of interest to the university administration. a. The 250 students that data was collected from.
b. The entire set of students that park at the university.
c. The entire set of students, faculty and staff that park at the university.
d. The students that park between 9 and 10 A. M on wednesday.

What is the rotational symmetry of a wheel

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 > ?
