Answer:

Step-by-step explanation:
Given
 --- male committing a crime in an episode
 --- male committing a crime in an episode
 -- Number of episodes
 -- Number of episodes
Required
Determine the probability of male committing a crime at least 3 times
This question illustrates binomial distribution and will be solved using;

So, the required probability is represented as:

And will be calculated using:














So:



 
        
             
        
        
        
The answer is 3. To find the interquartile range, all you have to do is subtract your Q3-Q1. In this case, all you do is 
20-17=3
        
                    
             
        
        
        
Answer:
2.5
Step-by-step explanation:
 
        
                    
             
        
        
        
122
286-42=144
144\2=122
122(peter)+164(malco)=286(total weight)
        
                    
             
        
        
        
If I remember correctly, the solutions are only on the solid line or in the shaded area? therefore Answers could be:
6.) (-3,0.5) (-4,0) (-2,0) (-2,-5) (-3,-5) (-4,-1) (-3,-1) (-2,-1)
7.) (-1,0) (-2,0) (-3,0) (0,-1) (-4,-1)
