Answer:
0.14285714285
Step-by-step explanation:
divide on calculator and make sure to have negative sign before three, remember you are dividing fractions
I hope it helps! If not sorry :(
 
        
                    
             
        
        
        
 y = a(x - b)^2 + c     has vertex  (b , c)
so here the vertex is (1, -36)
        
             
        
        
        
 The correlation coefficient r of the data set is <em>-0.28</em>
 
        
             
        
        
        
Answer:
distributive
Step-by-step explanation:
the number out side the parenthesis, 3 in this case, is being distributed to the numbers inside the parenthesis 
 
        
                    
             
        
        
        
P(A) = 0.993 is the probability of event A
    _
P(A) is the probability of not A (note that I am trying to place a bar over A. I hope you can see it, else it is because the editor did not show it as I intended)
Then, use the fact that the probability of A plus the probability not A is equal to 1:
                    _
=> P(A) + P(A) = 1
         _
=> P(A) = 1 - P(A) = 1 - 0.993 = 0.007
So, the answers are:
        _
1) P(A) = 0.07
             _
2) Yes, A is unlikely because its probability is very low.
