Answer:
2.86 miles.
Step-by-step explanation: 
We have been given that Megan uses a pedometer to find how many steps she takes each school day. she took 32,410 steps over the course of 5 days.



 
 
1 feet = 12 inches.
 
 
 
 
 
 
 
 
 
 
Therefore, Megan walks 2.86 miles on Monday.
 
        
                    
             
        
        
        
Answer:
 
   
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 138
Average = 32.6 inch
Population variance,

We have to find a point estimate for the population variance of the height.
The point estimate for the population variance is the population variance itself.

Thus, the point estimate of population variance is the population variance that is 2.8.
 
        
             
        
        
        
Answer:
see below
Step-by-step explanation:
7,12,16,20,27,40,56,64
The square numbers are 16 = 4^2   and 64 = 8^2
The difference is 64 - 16 =48
The cube numbers are 27 = 3^3 and 64 = 4^3
64 - 27 =37
 
        
                    
             
        
        
        
Yes, we apply the distributive property to simplify this expression.
3*5 = 15
6*3 = 18
15 + 18 is the final answer.
