Answer:
a. Concentration of nitrogen in water draining from fertilized lands
b. Quantitative
c. Water draining from fertilized lands
Step-by-step explanation:
a. Here we are evaluating the Concentration in miligrams of Nitrogen per liter of water, that drains from fertilized lands.. So thats what is defined as the variable.
b. When we talk about qualitative variblaes, we refer to variables that we can't define with numbers. For example the colour of a car, that's a qualitative variable. In this problem, can put a number on the nitrogen concetration. When we can measure the variable with numbers we consider it to be a quantitative variable. Therefore this is a quantitative variable
c. The implied population is the population where we want to interfer the analysis. In here we want to know the concentration of water draining from fertilized lands. So we are using random samples from a lake, and we extrapolate that analysis to a bigger universe, that it´s the water draining from fertilized lands

Answer:
Profit $5700
Step-by-step explanation:
To find loss/profit you subtract the expenses from the total income
Income from sales= $16000
Franchise fee= 5% of sales income
Rent=$1250
Utilities=$450
Wages=$4800
insurance=$300
supplies=$2700
Total expenses
=$1250+$450+$4800+$300+$2700+$800=$10300
Total income
=$16000
Profit
=$16000-$10300=$5700
