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:

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

The answer is c b/c you multiply
Answer:Rate of change is 7
Option B is correct.
Step-by-step explanation:
We need to find the average rate of change for
from x = 4 to x = 6
The formula used to find average rate of change is:

Where b = 6 and x = 4
Finding f(6):

Finding f(4):

Now Putting values:


So, Rate of change is 7
Option B is correct.
