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:
C. 20
Step-by-step explanation:
Take a value from the x-axis (Width) and the y-axis (Height) and substitute them into the equation. I'll use the point (5, 4).
Height = Constant/Width
4 = Constant/5 (Given)
20 = Constant (Multiplied 5 on both sides)
D

Answer:
mean: 2.6, mode: 1, median: 1
Step-by-step explanation:
The mean is essentially the average of the data set which can be defined as: 
. So adding all the values together you get: 
. and counting all the numbers in the data set you find the data set has 10 numbers. This gives you the equation: 
which is the mean
To find the mode, you find which number occurs most frequently, this is of course 1, which can really be determined by just looking at the data set for a second. all the other numbers only occur once, while 1 is in the data set 5 times. So 5 is the mode
To find the median you sort the data, from min to max, and then find the middle number. Sorting the data set gives you. -2, 1, 1, 1, 1, 1, 4, 5, 6, 8. Since this data set has an even amount of numbers, there is not going to be an exact middle. If you go the "middle" which is the 5th and 6th number, you add these two numbers and divide the sum by 2. This gives you: (1+1)/2 = 1 So the median is 1
School A : 750 + 200 = 950 per semester
School B : if u get a 10% discount, then ur actually paying 90%
0.90(1000) = 900 per semester
The best deal would be school B...u would save $ 50 per semester by choosing B over A
