For this discussion, you will investigate population statistics for either any three countries, any three states, or any three cities. (You can probably find the most recent available figures on Wikipedia.) You can choose whichever countries, states or cities you want. Based on those statistics, answer the following questions:
1.Which one has the largest current population?Which one has the smallest?
2.Which one has the largest current rate of population growth, measured as a percent? Which one has the smallest?
3.Will the largest country/state/city always have the largest rate of growth? Why or why not?
4.Using exponential models, make a prediction about the population of your three countries/states/cities in 10 years.

If you answer 2+2 you will get over 80 points

Does anyone know how to solve and graph this: 4 + | a + 2 | < 7the only part i don't get is the "4 +"

Name and describe the three most important measures of central tendency. choose the correct answer below. a. the mean, sample size, and mode are the most important measures of central tendency. the mean of a data set is the sum of the observations divided by the middle value in its ordered list. the sample size of a data set is the number of observations. the mode of a data set is its highest value in its ordered list. b. the sample size, median, and mode are the most important measures of central tendency. the sample size of a data set is the difference between the highest value and lowest value in its ordered list. the median of a data set is its most frequently occurring value. the mode of a data set is sum of the observations divided by the number of observations. c. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is the product of the observations divided by the number of observations. the median of a data set is the lowest value in its ordered list. the mode of a data set is its least frequently occurring value. d. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is its arithmetic average. the median of a data set is the middle value in its ordered list. the mode of a data set is its most frequently occurring value.
