Question
The arithmetic mean M of the five numbers a, b, c, d, e is equal to their sum divided by the number of quantities. Express it as a formula.
Solution
Sum of a, b, c, d, e = a + b + c + d + e
Number of quantities = 5
Sum divided by the number of quantities = `("a" + "b" + "c" + "d" + "e")/(5)`
As per the data: M = `("a" + "b" + "c" + "d" + "e")/(5)`.
