7.2 units is the distance between the two points (-5,3) and (1, -1). 
The formula used for determining the distance between two points is shown below. In case this equation is used for finding the distance between the origin and a point, the value of x1 and y1 would just be equal to zero. 
distance = 
The given points can be directly substituted for the formula. 
Let: x2= 1, x1= -5, y2= -1, and y1= 3
distance = ![\sqrt{[1-(-5)]^{2} + (-1 -3)^2 }](https://tex.z-dn.net/?f=%5Csqrt%7B%5B1-%28-5%29%5D%5E%7B2%7D%20%2B%20%28-1%20-3%29%5E2%20%7D)
distance = 
distance =  or 7.21 units
 or 7.21 units
When rounded to the nearest tenth, the distance between the two points would be 7.2 units.

A proportional relationship is just a linear relationship where b = 0, or to put it another way, where the line passes through the origin (0,0).
 
        
                    
             
        
        
        
ANSWER
D. 4 minutes 40 seconds
EXPLANATION
The given data set showing the number of seconds of each song the playlist is:
283,204,198,229,173,230,168,236,215,204
Let the length of the 11th song be x.
Because he wants the mean to be 3 minutes 40 seconds, which is equal to 220 seconds, we write and solve the following equation for x.





We convert 280 seconds to minutes.

The correct choice is D
 
        
             
        
        
        
K=-9 Bc you move the variable to the left and then collect like terms and divide both sides
