Explanation / Answer

3) A weighted mean is a kind of average. Instead of each data point contributing equally to the final mean, some data points contribute more “weight” than others. If all the weights are equal, then the weighted mean equals the arithmetic mean (the regular “average” you're used to).

WM = (0.3 * 2500 + 0.25 * 1500 + 0.5 * 3000)/7000v=v37.5 or 38
