The mean weight of 8 numbers is 15. If each number is multiplied by 2, what will be the new mean?

Explanation

To solve the problem, we need to determine the new mean after each number in a set is multiplied by 2. Here’s the step-by-step solution:

### Step 1: Understand the given information
We know that the mean weight of 8 numbers is 15. This means that if we denote the numbers as \( x_1, x_2, x_3, \ldots, x_8 \), the mean can be calculated as:
\[ \text{Mean} = \frac{x_1 + x_2 + x_3 + \ldots + x_8}{8} = 15 \]
