How much greater is the shared variance between two variables if the pearson correlation coefficient between them is –.4 than if it is .2?

The variance is twice as big since it doesn't account for sings

there is no

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
