Assume the box contains 9 balls:
4 red, 2 blue, and 3 yellow. a ball is drawn and its color noted. if the ball is yellow, it is replaced; otherwise, it is not. a second ball is then drawn and its color is noted.

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

Let f(x) = 3 − x . find the average rate of change of f(x) from x = a to x = a + h and simplify your answer so that no single factor of h is left in the denominator.

What is the solution to the system of equations? y=1.5-3 y=-x
