Answer 1

Answer:

(i) The basic formula for a weighted average where the weights add up to 1 is x1 (w1) + x2 (w2) + x3 (w3), and so on, where x is each number in your set and w is the corresponding weighting factor. To find your weighted average, simply multiply each number by its weight factor and then sum the resulting numbers up.
