In correlation coefficient analysis, the value of r represents the degree of correlation. The closer the value is to 1, the more likely that a direct positive correlation exists. The closer the value is to -1, the more likely that a direct negative correlation exists. However, if the value of close to 0, then there is likely no or very low correlation. Therefore, the value representing low or no correlation in the given values is -0.001.

What must be added to x - y to obtain y-x?

Lera25 [3.4K]

To make x-y reasonable, you must make x the same value as y. It is the same as y-x. But a different variable order. For example x= 6 and y=9, and x - y is unreasonable, to make it reasonable, you must add 3 more to x to make it the way of y - x. So, your answer is just like 9-9 or 10-10 or any other subtraction equation with equal value, you don’t have to know what the variables equal, you just have to take an example and try it, that’s all you need to do to get out of the tricky problems. Hope this helps and have a great night of sleep :))

Ralphie has a large tropical fish collection. He gives 2/3 of his fish to a local high school. Then he gives 2/5 of the remainin

Lubov Fominskaja [6]

Let initially number of fishes =x

He gives 2/3 of his fish to a local high school, that is he gives 2x/3 fish .

So number of fishes left = x -(2x/3) = x/3 . And he gives 2/5 of x/3 to an elementary school , that is , he gives 2x/15 fishes to the elementary school. And finally the number of fishes left =30 , that is

$x-(\frac{2x}{3}+\frac{2x}{15})=30$

$x-\frac{12x}{15}=30$

$\frac{3x}{15}=30$

$x = 150$

So initially he have 150 fishes .
