(a) Write the information in each Table as a matrix.
(b) Use the matrices from part (a) to find the total number (in millions) of births and deaths in each year (assuming birth and death rates for all years are close to these in 2010).
(c) Using the results of part (b), compare the number of births in 1970 and in 2010, Also compare the birth rates from part (a). Which gives better information?
(d) Using the results of part (b), compare the number of deaths in 1980 and in 2010. Discuss how this comparison differs from a comparison of death rates from part (a).

- Urban Travel Times Population of cities and driving times are related, as shown in the accompanying table, which shows the 1960 population N, in thousands, for several cities, together with the average time T, in minutes, sent by residents driving to work. City Population N Driving time T Los Angeles 6489 16.8 Pittsburgh 1804 12.6 Washington 1808 14.3 Hutchinson 38 6.1 Nashville 347 10.8 Tallahassee 48 7.3 An analysis of these data, along with data from 17 other cities in the United States and Canada, led to a power model of average driving time as a function of population. a Construct a power model of driving time in minutes as a function of population measured in thousands b Is average driving time in Pittsburgh more or less than would be expected from its population? c If you wish to move to a smaller city to reduce your average driving time to work by 25, how much smaller should the city be?arrow_forwardBronze is an alloy of copper, zinc, and tin with small amounts of other elements.
