The strategy for these is to look at what these problems are telling you. 
It says the y-value, so you know that this is a y = equation.
y = what? 
y = 2 more than. 4 is two more than 2, right? So saying it's more than is another way of saying "y is 2 + blah blah."
So y = 2 + what? Three times the x-value. What does that mean? 3*X = 3X.
Thus we arrive at the final answer, y = 3x + 2
        
             
        
        
        
Answer:
7/6
Step-by-step explanation:
1/3=2/6
2/6+5/6=7/6
 
        
                    
             
        
        
        
575% as a mixed number would be 5 3/4

Answer:
The estimate for the proportion of Americans over 33 who smoke is 0.28.
Step-by-step explanation:
Proportion of Americans over 33 who smoke.
Number who smoke divided by the size of the sample.
In this question:
Sample of 1267.
913 don't smoke, so 1267 - 913 = 354 smoke. Then

The estimate for the proportion of Americans over 33 who smoke is 0.28.
