The scatter plot shows the relationship between the number of hours spent practicing piano per week and the number of pieces of music the student can play:
part a: what is the group of points labeled t called? what is the point labeled r called? give a possible reason for the presence of point r. (3 points)
part b: describe the association between the number of hours practiced each week and the number of pieces a piano student can play. (2 points)

Part A :  T is a Nonlinear Positive Association, R is an outlier. R could have been that one song or pecie that he couldnt play correctly.

Step-by-step explanation:

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

it would open into a square depending on the type of envelope i’m not sure about the second part
