7 because 8+7 is equaled to 15
In the research of Professor Nwamabi the use of air conditioning represents independent variable.
Given 100 participants are randomly selected in a research in which effects of air conditioning on sleep habits is studied.
Dependent variable is the variable whose value is dependent on the other variables like increase in profit and production.
Independent variable is the variable whose value is not dependent on the other variables.
In the research of Professor Nwamabi in which he is examining the effects of air conditioning on sleep habits, use of air conditioning represents independent variable. In this study the effect is on sleep habits means the value of sleep habits will change due to use of air conditioning. It shows that the use of air conditioning is not depending on other variable in the research.
Hence the use of air conditioning represents the independent variable.

Answer:
Step-by-step explanation:
When y varies jointly as x and z, the equation is written ...
y = k·x·z
Here, the joint variation is not with z, but with z². There is also an inverse variation with w, so the entire relation is ...
y = k·x·z²/w
We want to find the value of k for the given values of the variables. So, we can solve for k to get ...
Then the equation of variation is ...
