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:

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc

answer is because 4×10=40

and 98×4= is 392

40,392
