disa [49]

Answer:

(4) s = 20

Step-by-step explanation:

Given system:

r + 2s = 52
2r - s = 4

Eliminate r to solve for s.

To do so, double the first equation and then subtract the second one:

2r + 4s = 104
2r - s = 4

Subtract

4s - (-s) = 104 - 4
5s = 100
s = 100/5
s = 20

Correct choice is (4) 20

Answer:

C. 2

Step-by-step explanation:

Cohen's d is a parameter used to express the standardised difference between two means. It is defined as the difference between the means divided by the pooled standard deviation.

In this case, the difference between both means (M2-M1) is 8. As for the pooled standard deviation, simply take the square root of the given pooled variance:

$S=\sqrt{S^2}\\S=\sqrt{16} \\S= 4$
