Answer:
  
Step-by-step explanation:
Using the slope formula, you can form this equation! The slope of any equation would replace the m, and the y intercept would replace b!
I added in the slope formula at the bottom, just in case, so you'll see what I mean! 
I hope this helps, and I explained enough! Have a great day c:
 
        
                    
             
        
        
        
I don’t think he did distributive property
        
             
        
        
        
I would assume 1/5 is your answer. As 1/5+1/5+1/5+1/5+1/5 = 5/5 which is 1.
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
Given parameters: 
Number of white balls  = 24
Number of black balls  = 16
Unknown: 
The probability that white ball is drawn at random = ? 
Solution: 
The probability of an event is the likelihood of such an event to occur. That an event will occur has a probability of 1, it will not occur have a probability of zero. 
In this problem, the total number of outcomes of drawing any ball has sample space of (24 + 16)outcomes  = 40outcomes. 
 Probability of an event  = 
                   Pr(white balls) = 
   =
