Singers. The frequency table shows the heights (in inches) of 130 members of a choir. Count Count 2 5 6 11 9 8 Height 60 61 62 63 64 65 66 7 Height 69 70 71 72 73 74 75 76 9 4 2 20 18 7 4 67 1 68 12 a) Find the median and IQR. b) Find the mean and standard deviation. Make sure to account for the frequency of each height.

The median of a data set is the measure of center that is found by adding the data values and dividing the total by the number of data values that is the value that occurs with the greatest frequency that is the value midway between the maximum and minimum values in the original data set that is the middle value when the original data values are arranged in order of increasing (or decreasing) magnitude

The functions f(x) and g(x) are shown in the graph f(x)=x^2 what is g(x) ?

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 > ?
