A weight is suspended from a spring and allowed to hang at its rest position. It is then pulled down 2 inches, released, and allowed to oscillate up and down. Its location (in inches) relative to its rest position is given by the function f(t)= 2sin(2.5t - pi/2), where t is the time in seconds. How much time will it take for the weight to move through one complete cycle of motion?

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
