You are correct. The higher the standard deviation is, the more spread out the data set will be. Nice work.
 
        
             
        
        
        
Answer:
x = 3
Step-by-step explanation:
2x - y = 4
x + y = 5
y = 5 - x
2x - (5 - x) = 4
2x + x - 5 = 4
3x = 9
x = 3
 
        
             
        
        
        
Answer: you can only add like terms, for example; 2x + 3x = 5x as they both have an x next to the numbers.
you cannot simplify 2 + 4x as they both don’t have an x next to them.
hence why, the answer to 2x^2 + 15x^2 would be 17x^2
