Question

what is the mean? -8 3 -9 -9 -9 -1 -8 1

Explanation:

Step1: Sum the numbers

First, we add up all the given numbers: \(-8 + 3 + (-9) + (-9) + (-9) + (-1) + (-8) + 1\)
Let's calculate step by step:
\(-8 + 3 = -5\)
\(-5 + (-9) = -14\)
\(-14 + (-9) = -23\)
\(-23 + (-9) = -32\)
\(-32 + (-1) = -33\)
\(-33 + (-8) = -41\)
\(-41 + 1 = -40\)

Step2: Count the numbers

There are 8 numbers in total.

Step3: Calculate the mean

The mean is the sum divided by the number of values. So, the mean \(= \frac{-40}{8} = -5\)

Answer:

\(-5\)
