Answer:
Mean = 1.9
Standard deviation = 0.6
Step-by-step explanation:
The Mean is calculate by the formula:

⇒ 
Thus Mean to the nearest tenth is 1.9
Standard Deviation is the square root of sum of square of the distance of observation from the mean.  
 
where,  is mean of the distribution.
 is mean of the distribution.
Putting all values in the formula, We get
Standard Deviation = 0.597 ≈ 0.6 
 
        
             
        
        
        
I got you hun!
27= 3x is the equation you will need
27 is the total the coach needs making it the total. Since each pack comes with 3 you will mutiply the amount of pack, or x, by 3. 
X=9 
we know this because if you divide 3 by 27 to get it on the other side we get 9. This means the coach needs to buy 9 packs of baseballs for the team.
27=3(9) 
Hope this helps!
        
             
        
        
        
Six is the answer because a hexagon has 6 similar sides.
        
             
        
        
        
-3x + 6 + 12 y. I am afraid that there are no like terms to combine, and it is neither an equation nor an inequality. 
Hope this Helps!
