95% Confidence interval:  (0.8449,0.9951)
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 50
Number of times the dog is right, x = 46
 
95% Confidence interval:
 
 
Putting the values, we get:
 
(0.8449,0.9951) is the required 95% confidence interval for the proportion of times the dog will be correct.
 
        
             
        
        
        
Step-by-step explanation:
Let x = number of games that Alex played 
The total money that he spent C is given by
 
 
If he spent $45, then we can write

This means that Alex played 15 games.
 
        
                    
             
        
        
        
The answer is c. we add 4x^4+x^4. then cancel the -x^2+x^2 and also the -x and x . so, we are left with the -1. that's why the answer is c
