zloy xaker [14]

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

Therefore, the value of Cohen's d (d) is:

d=\frac{M_{2} -M_{1}}{S} \\d=\frac{8}{4}\\d=2

It's -18.

-1/6b=3

Multiply the reciprocal of -1/6 to both sides, this will get x by itself

(-6/1)*-1/6b=3*(-6/1)

b= -18/1
b= -18

Answer:

Hi  , the answer is 280-140/ 4-2 = 140/2  

y = 2/140 x

b .  70 beats each minute

Step-by-step explanation:  

we will  take a 2 point from the graph

(280,4) , (y1,x1)    and (140, 2) , (y2,x2)      each point represent a (y,x)  point

m = y1-y2 / x1-x2   = 280-140 / 4-2 = 140 /2

now , y/x = 140/2 ... by B. Multiplication we will get y = 2/140 x  

b .

from the graph we see that every minute  the curve increase 70 beats

Thanks
