Answer:
8:00 to 9:00am
Step-by-step explanation:
7 plus 14=21 21-12= 9 am so between 9:00 and 10:00 am

50.27
Step-by-step explanation:
area of a circle: pi X r^2
r= radius
 
        
                    
             
        
        
        
Answer:
25. Yes, it is a function, because none of the x outputs are repeating
 
        
                    
             
        
        
        
Answer: C. (3,-2) (-6,-9) (-6,9) (-9,6) (9,6)
 
        
             
        
        
        
Answer:
From the central limit theorem we know that the distribution for the sample mean  is given by:
 is given by:
 

And now for the deviation we have this:

So then the correct answer for this caee would be: 
c. 1.30 ounces. 
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".  
The central limit theorem states that "if we have a population with mean μ and standard deviation σ and take sufficiently large random samples from the population with replacement, then the distribution of the sample means will be approximately normally distributed. This will hold true regardless of whether the source population is normal or skewed, provided the sample size is sufficiently large".
Solution to the problem
From the central limit theorem we know that the distribution for the sample mean  is given by:
 is given by:
 

And now for the deviation we have this:

So then the correct answer for this caee would be:
