Let p be 0.831 denote the percentage of defective welds and q be 0.169 denote the percentage of non-defective welds.
Using the binomial distribution, we want all three to be defective.


 
 
        
        
        
In scientific notation, in would be 6.3825*10 to the 4th power
        
             
        
        
        
Answer:
slope is -2 and the y-intercept is 12 
Step-by-step explanation:
a key thing to remember: x is always equal to 0 when finding the y-intercept. 
so if you look at the table for where 0 is, you get the point (0,12) meaning the y-intercept is 12. 
to find the slope use the equation: slope= change in y/change in x
you can use any two points to find this. 
lets take the points of the x-intercept (6,0) and the y-intercept (0,12) 
12-0/0-6 
12/-6
-2 = slope 
 
        
             
        
        
        
I believe it would be -17m-4/8
