5.3+Finding+Population+Densities

VB 21 Feb Big Idea: Many important practical and mathematical applications involve comparing quantities of one kind or another; it is important to know which method to use and how we should use them. // Essential Question: // // What methods are there for comparing things? // 5.3 And Follow Up: Finding Population Densities. Notes: pd=p/a 5.3 A) What is population density of the census region in which you school is located? Since we are in Bangladesh it will be 150,448,339/143,980=1044.925260452840672315599388804 and with the rounding it will be 1044.93.  B) For you country, find the population density and compare it to five other places. Since I am from India I do 1103371000/3287263=335.65035715122276495674364965626 the rounded form is 335.65. The five other places I pick are UK, Sweden, Mexico, Switzerland, and USA. UK: 60776238/242900=250.21094277480444627418690819267 the rounded form is 250.21. Sweden: 9041262/449964=20.093300797397125103341600661386 the rounded form is 20.09. Mexico: 104266000/1958201=53.245810823301591613935443807862 the rounded form is 53.25. Switzerland: 728233/41284=17.639594031586086619513613021994 the rounded form is 17.64. USA: 305825000/9629091=31.760526512834908300274657285927 the rounded form is 31.76. India’s population density is larger then all the other countries I picked. C) Order the countries from least crowded to most crowded. Switzerland  Sweden  USA  Mexico  UK  India  D) India had the greatest population. The other counties are less by at least one hundred. The difference between the least populated and India is 318.01. FU What do you think accounts for the differences in population densities among the regions? In other words, why do you think some areas are densely populated and other are more sparsely populated. I think that is because a few places have better living abilities and are less costly.
