Use the chart below to answer the questions: Country Population (1997 estimate) Area (square km) U. S. 272,648,000 9,364,520 Romania 22,609,000 237,391 Ghana 18,339,000 237,533 Which of these countries has the greatest population density? Which has the least? Provide an explanation and proof for your answer to receive full credit.

Romania has the greatest population density (95.24) and U.S. has the least (29.12). It means that there are more inhabitants per square kilometer in Romania than in Ghana and US. and that there are less inhabitants per square kilometer in U.S. than in Ghana and Romania.

Step-by-step explanation:

         Country Population (1997 estimate) Area (square km)

U.S.                272,648,000                                9,364,520

Romania         22,609,000                                   237,391

Ghana             18,339,000                                    237,533

Which of these countries has the greatest population density? Which has the least? Provide an explanation and proof for your answer to receive full credit.

Let's recall the formula of the population density:

Population density = Country population/Area

U.S. 272,648,000/ 9,364,520 = 29.12 (rounding to the next hundredth)

Romania 22,609,000/ 237,391 = 95.24 (rounding to the next hundredth)

Ghana 18,339,000/ 237,533 = 77.21 (rounding to the next hundredth)

Romania has the greatest population density (95.24) and U.S. has the least (29.12). It means that there are more inhabitants per square kilometer in Romania than in Ghana and US. and that there are less inhabitants per square kilometer in U.S. than in Ghana and Romania.

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
