What's the longest you should leave a tampon in?

Depending on your flow... some brands say 4 - 8 hours. When you try to remove it and it is uncomfortable it may be because the tampon hasn't reached its max absorption. Do not be alarmed. Just leave it in longer next time or get a less absorbing one.

Explanation:

34.4 miles

Step-by-step explanation:

Mathematically;

z-score = x-mean/SD

from the question, we have mean as 29 and standard deviation as 3.6 with z-score as 1.5

So we need to find the z-score here

1.5 = x-29/3.6

3.6 * 1.5 = x-29

5.4 = x-29

x = 29 + 5.4

x = 34.4
