It shows a positive correlation 
Just go from the very left of the graph to the very right and see, if the points go up or down.
Or pick off some points to see the trend
(2,1) (3,2) and (5,4)
These points show that over time the number of typos go up with the number of pages printed.
 
        
             
        
        
        
Answer: Y= 2/3x + 9
Explanation: The equation is in slope-intercept form, y=mx+b. Since it is parallel to the equation, it has the same slope (2/3x) and since b is the x intercept, b is 9.

Start by doing the binomial expansion of (x+y)^6 where x represents success. This is 
(x^6y^0) + 6(x^5y^1) +15(x^4y^2) +20(x^3y^3) +15(x^2y^4) +6(x^1y^5) +(x^0y^6) 
We are interested in the x^3y^3 term which represents exactly 3 sucesses. Since the probalbility of sucess and failure are both .5 we should be able to figure this out just using the coefficients of the terms which is 
20/64 = .3125 which is 31.25%
