The frequency distributions of two data sets are shown in the dot plots below.

which of the following statements are true. check all that apply.

-the mean of data set 1 is greater than the mean of data set 2.

-the mean of data set 1 is equal to the mean of data set 2.

-the median of data set 1 is greater than the median of data set 2.

-the median of data set 1 is equal to the median of data set 2.

-the standard deviation of data set 1 is smaller than the standard deviation of data set 2.

-the data sets have the same interquartile range.

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 > ?
