Answer:
a) The variable of the study is: milligrams of nitrogen per liter of water.
This is the amount that needs to be measured and analyzed to reach conclusions in the study.
b) The variable is quantitative. The quantitative variables are those that represent quantities. This variables can be measured on a continuous or discrete scale. Then, all the variables that you can measure or count are quantitative variables(height of trees, number of passengers per car, wind speed, milligrams of nitrogen per liter, etc). On the other hand, qualitative variables are those that can’ t be measured, and they represent attributes, like apple colors (red, green), size of trousers (small, medium, large) and so on.
c) The population under study is the milligrams of nitrogen per liter of water that are in the entire lake. You can estimate the parameters of the population by taking samples (In the example, 28 samples are taken).

3 remainder of 7 i fink
Step-by-step explanation:
Answer:
c
Step-by-step explanation:
if you take 30 and divide by two you get 15 and 15. 15 divided by 3 is 5,5,5 and if you did two thirds then you would have five problems left
10x^2yz - 22x^3
=2x^2 (5yz - 11x)
Hope this helps!
