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.  part b:   describe the association between the number of hours practiced each week and the number of pieces a piano student can play. will give brainyist to person who answers both parts

     PART A:  

       The groups under the label T are in a positive linear association. The dot under the label R has no association. The presence of R might be because one student decided to time his/her self to see how much music he/she can play in 3 hours. In this case, 70 sheets of music.

PART B:        

       The association between the number of hours in each week and the number of pieces a piano student can play is based on what each students limits are. If some students want to go all the way for each day, then they will have more music played in more hours. If some students want to limit themselves for each day, then their music played and their time spent will be shorter. If some just want to do a certain amount of music in a certain amount of time, then their dot will be in the somewhere middle.

thats my best guess hope it helps =P

-2 is the right

required rate of return = 0.166 = 16.6%

step-by-step explanation:

under the capital asset pricing model (capm), the required or expected rate of return for a particular security or asset is given using the formula:

required rate of return = risk-free rate + beta*(market risk premium)

we are given that;

risk-free rate = 4% = 0.04

beta = 1.4

market risk premium = 9% = 0.09

we simply plug these values into the above formula;

required rate of return = 0.04 + 1.4*(0.09)

required rate of return = 0.04 + 0.126

required rate of return = 0.166 = 16.6%
