answer is 13
Step-by-step explanation:
Using the BODMAS rule,bracket of division or multiplication, addition or subtraction.
This applies the rule:
therefore,
23- (12+6)+8 ,calculate within bracket first
=23-(18)+8
now remove the bracket,by multiply by the -1
=23-18+8
the start calculate from the left to right
=23-10
=13
therefore the answer is 13
Answer:
13
23-(12+6)+8
23-18+8
31-18
2x^2
2x*1x= 2x^2
1

1 pints out of every 1.2 gallons.
3.75/3.75 = 1
5/3.75 = 1.33 repeating
n = 22
Using
n = p(1-p)(Zc/E)²
From table E = 0.2 while p= 0.37
So substituting
We have n= 22.4
Thats a sample size of approximately 22
