<span>Which ordered pair is the best estimate for the solution to the system?
</span>A. (2, −6.5)
        
                    
             
        
        
        
10cm
5cm is shown above all u gotta do is multiply by two OR add 5+5 to get 10 cm.
        
             
        
        
        
The answer is 5/6 because you need to flip the numbers.
        
             
        
        
        
Answer:
a
    The  null hypothesis is  
     The  alternative hypothesis  
b
  The   95% confidence interval is  
Step-by-step explanation:
From the question the we are told that 
       The  population mean is  
       The  sample size is  n = 30 
        The  sample mean is  
        The standard deviation is  
      
Given that the confidence level is   then the level of significance is mathematically represented as
 then the level of significance is mathematically represented as 
                   
                   
=>               
Next we obtain the critical value of  from the normal distribution table
 from the normal distribution table 
     The value is  
Generally the margin of error is mathematically represented as 
                  
substituting values 
                 
                 
The 95% confidence interval confidence interval is mathematically represented as 
               
substituting values 
                
                 
 
        
 
        
             
        
        
        
Hi,
To find the number of small cylinders that fit inside the big cylinder. You need to divide volume of small cylinder with the volume of big cylinder. We do this by using formula to calculate volume of cylinder:

To find radius just divide diameter with 2.

Now just division:

Answer: You could fit 374.8 smaller cylinders inside a big cylinder.
Hope this helps.
