Find the mean of the following distribution: x:           10               30               50               70               89 f:            7                 8                 10               15               10

Explanation

To find the mean of the given distribution, we will follow these steps:

### Step 1: Write down the values of x and f
The values of x and their corresponding frequencies (f) are given as follows:
- x: 10, 30, 50, 70, 89
- f: 7, 8, 10, 15, 10

### Step 2: Calculate the product of x and f (i.e., x * f)
