Rhonda needs to continue taking samples of ducks until both samples have at least one of each type of duck.
OR Ja should take a third sample and then use the two that are most representative since these samples vary quite a bit.
O Rhonda should use both of these samples as they are to make inferences about the average population of each type of
Park in the pond.
O Both samples must be biased because there are more Mallards than any other type of duck recorded in the sample.

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 b suppose 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 c now try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
