Playing violin causes students to get better grades.  

is a reasonable conclusion

Step-by-step explanation:

Given that the correlation coefficient for practicing violin and getting better grades in a group of people is 0.8.

If practicing violin time is taken as x and getting better grades is taken as y then we are given that x and y are positive strong correlated.  Strong because correlation coefficient is >0.5

Hence the given conclusion is reasonable.

Playing violin causes students to get better grades.  

D No; even though there is a strong positive correlation, playing violin doesn't cause students to get better grades

I just took the test

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792
