Which of these r-value represents the strongest correlation -0.5 -0.7 -0.4 -0.6

-0.7

Step-by-step explanation:

We know that when the absolute value of correlation coefficient 'r' is nearest to 1 then then we say that it represents the strongest correlation.

From the given options, the absolute value of -0.5=0.5

The absolute value of -0.7=0.7

The absolute value of -0.4=0.4

The absolute value of -0.6=0.6

We can see that the absolute value of -0.7 i.e. 0.7 is nearest to 1.

Therefore , the value of r =-0.7 represents the strongest correlation.

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
