Answer:
I believe it is 48%
Step-by-step explanation:
The total amount of people who liked to read printed books is 67.
Then the total amount of people who liked either print or electronic books is 140.
If I am remembering correctly, you would divide 67 by 140 to get the percentage of people who like to read printed books.
<u>67/140 = 48%</u> (rounded)

Answer:
Step-by-step explanation:
If two ratios make a proportion then it can be shown as:
Let's verify the answer choices with this method
A. 1/4 and 5/25
- 1*25 = 4*5
- 25 = 20, incorrect, not a proportion
B. 1/4 and 7/24
- 1*24 = 4*7 
- 24 = 28, incorrect, not a proportion
C. 1/4 and 10/48
- 1*48 = 4*10
- 48 = 40, incorrect, not a proportion
D. 1/4 and 9/36
- 1*36 = 4*9
- 36 = 36, correct, this is a proportion
 
        
             
        
        
        
P(A) = 1/4
p(B) = 2/3
p(A ∩ B) = 1/5
p(A).p(B) = 2/12 = 1/6 ≠p(A ∩ B ) 
thus no, they are dependent because P(A) ⋅ P(B) ≠ P(A ∩ B)
        
             
        
        
        
Answer:

Step-by-step explanation:
From the diagram, side length  is opposite to angle A and side length
 is opposite to angle A and side length  is adjacent  to angle A.
 is adjacent  to angle A.
Recall the mnemonics SOH CAH TOA.
We use TOA, because it involves opposite and adjacent.


The correct choice is A.
