To find the mean number of absent students per day at Brighton Middle School, follow these steps:

1. Record the number of absent students for each day of the week:
- Monday: 11
- Tuesday: 9
- Wednesday: 6
- Thursday: 9
- Friday: 9

2. Calculate the total number of absent students for the entire week:
[tex]\[ 11 + 9 + 6 + 9 + 9 = 44 \][/tex]
The total number of absent students for the week is 44.

3. Count the number of days:
There are 5 days in the week.

4. Calculate the mean (average) number of absent students per day:
[tex]\[ \text{Mean} = \frac{\text{Total number of absent students}}{\text{Number of days}} = \frac{44}{5} = 8.8 \][/tex]

5. Round the mean to the nearest tenth if necessary:
In this case, 8.8 is already rounded to the nearest tenth.

Therefore, the mean number of absent students per day is [tex]\(\boxed{8.8}\)[/tex].

So, the correct answer is:
[tex]\[ 8.8 \text{ students per day} \][/tex]
