Question

What is the mean of the following integers?
-8, -5, 3, -9, 5, 2, 5

Answer 1

To calculate the mean of the integers \(-8, -5, 3, -9, 5, 2, 5\), follow these steps:

1. **Add the integers together:**

\[
-8 + (-5) + 3 + (-9) + 5 + 2 + 5
\]

Calculating step by step:

- \( -8 + (-5) = -13 \)
- \( -13 + 3 = -10 \)
- \( -10 + (-9) = -19 \)
- \( -19 + 5 = -14 \)
- \( -14 + 2 = -12 \)
- \( -12 + 5 = -7 \)

So, the sum of the integers is \(-7\).

2. **Count the number of integers:**

There are 7 integers in total.

3. **Calculate the mean:**

The mean is calculated by dividing the sum by the number of integers:

\[
\text{Mean} = \frac{\text{Sum}}{\text{Number of integers}} = \frac{-7}{7} = -1
\]

Therefore, the mean of the integers is \(\boxed{-1}\).
