Answer:
In parametric form:
Step-by-step explanation:
We first find the mid point:
Then, a vector parallel to the z-axis is:
Then remember the equation of a line passing through point
and parallel to the vector
is:
So, in this problem we get:
After combining the two vectors:
In parametric form:

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:

Answer:y=7
Step-by-step explanation:x=2+7=8
