I have to answer these questions with these graphs made how do i answer them
Answer:
A line graph is also used when there are two variables—but only makes sense when you're tracking changes over a continuous measurement (e.g., time, temperature, distance). Line graphs are especially useful for illustrating direction (i.e., peaks and dips) rather than magnitude.
Line graphs are used to track changes over short and long periods of time. When smaller changes exist, line graphs are better to use than bar graphs. Line graphs can also be used to compare changes over the same period of time for more than one group.
Deana is studying the table shown here, which lists the birthrate and death rate for several countries.
Country Birthrate
(per 1000 People) Death Rate
(per 1000 People)
Brazil 14.7 6.1
Cambodia 24.1 6.1
Italy 8.3 9.8
Mali 43.5 10.5
Venezuela 19.6 5.5
Deana applies the data in the table to calculate the rate of population increase or decrease of each country.
Which assumption is necessary for Deana’s calculations to be accurate?
A. The immigration and emigration rates of the countries are insignificantly small or approximately equal.
B. The immigration rates of the countries are much higher than the emigration rates.
C. The immigration rates of the countries are much smaller than the emigration rates.
D. The population is evenly distributed between rural, suburban, and urban areas.
In order to use only the birth and death rates to calculate the rate of population growth or decrease of a country, the immigration and the emigration rates must either be insignificant or approximately equal.
Population growth rateThe growth rate of a population is determined by the following equation:
Growth rate = (Birth rate - death rate) + (Immigration - Emigration)
Thus, if immigration is more or less equal to emigration or both factors are insignificantly small, the difference between the birth and death rates can be used to estimate the population growth.
