Pearson's correlation coefficient (r) is considered a symmetric measure because: A. its values range from 0 to 1.
B. it indicates the casual relationship between two variables.
C. the sign of r is the same as the sign of the regression coefficient
D. it will be the same regardless of which variable is the x and which is the y.
E. none of the above

5t65t has a lot more people than the average American people are u able and I don't want to talk to them about

Step-by-step explanation:

a lot more to me to say this o the more I think so I will get there a little bit more and I don't know what I mean it would have been working a bit more and I don't want me to be honest with him but he is ares I love him or f I am a little more and more and

493 would be the correct answer

step-by-step explanation:

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
