Answer:
A) Not mutually exclusive
Step-by-step explanation:
Given



Required
Determine if they are mutually exclusive or not
Mutually exclusive are defined by:

So, we have:

Take LCM


By comparing:
 ---- Calculated
 ---- Given
We can conclude that A and B are not mutually exclusive because:

 
        
             
        
        
        
Answer:each book cost 39 dollars

Answer:
19.5º
Step-by-step explanation:
Every triangle is equal to 180º for all angles. So, you add 33.5 + 127 and subtract the sum by 180. 
33.5 + 127= 160.5
180- 160.5 = 19.5
So, the angle F is 19.5º

What I did was I subtracted 4500 minus 500 because it was a fee then I divide 4400 by 35 and I got 125 people.
        
                    
             
        
        
        
Answer:
see explanation
Step-by-step explanation:
For a given scale factor k
If k > 1 then expansion
If k < - 1 then expansion in the opposite direction
If 0 < k < 1 or - 1 < k < 0 then contraction
k = - 2 ← expansion in opposite direction
k = 1.5 ← expansion
k = 
 ← contraction
k = - 
 ← contraction
