Answer: 0.2872
Step-by-step explanation:
Given : In a sample of 1000 randomly selected consumers who had opportunities to send in a rebate claim form after purchasing a product, 260 of these people said they never did so. 
i.e. n= 1000 and x= 260 
⇒ Sample proportion : 
z-value for 95% confidence interval : 
Now, an upper confidence bound at the 95% confidence level for the true proportion of such consumers who never apply for a rebate. :-



∴ An upper confidence bound at the 95% confidence level for the true proportion of such consumers who never apply for a rebate : 0.2872
 
        
             
        
        
        
Answer:
22.5°
Step-by-step explanation:
it's a right angle which equals 90° 
which is 4 times as much as x
so i just divided 90 by 4
however since you are using formulas it would be written
90 ÷ 4 = x
 
        
             
        
        
        
Since the shirt is 25 percent off your paying for 75 percent of the shirt. 0.75(36) is 27. The shirt will cost 27.00
