<h3>
Answer: false</h3>
Work Shown:
s = false
p = true
r = false
-p = false, which is the opposite of statement p
s or -p = false or false = false
The result of an 'or' operation is false only when both parts are false; otherwise, it is true
(s or -p) or r = false or false = false
(s or -p) or r = false
The standard deviation is 19.91.
To find the standard deviation is a binomial distribution, you have to take the square root of the total number multiplied by the percent and its compliment.
Our expression will be:

This will evaluate to about 19.91.
The answers is 2:10 or 2/10
The answer in decimal format is 15.7
Or 7 radical 5
When you put 31/6 to 5 1/6 and 8 2/9 to 8 2/9 and 11/2 to 5 1/2. Then you change the denominators to 18, so you get 5 3/18 + 8 4/18 - 5 9/18. So you add the 5 3/18 and 8 4/18 to get 13 7/18. Then you subtract 13 7/18 by 5 9/18 to get 7 8/18. simplest form you will get 7 4/9. Your welcome.
