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

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
