Concept explainers
(a)
To calculate: The function for the instantaneous rate of change of the percent of U.S. females workers, if the percent function of total U.S. females workers is model as
Year | % Females | Year | % Females |
1950 | 29.6 | 2010 | 47.9 |
1960 | 33.4 | 2015 | 48.3 |
1970 | 38.1 | 2020 | 48.1 |
1980 | 42.5 | 2030 | 48.0 |
1990 | 45.2 | 2040 | 47.9 |
2000 | 46.6 | 2050 | 47.7 |
(b)
To calculate: The instantaneous rates of change of the percent of the U.S. females worker in 2005 and 2020 respectively for the function
(c)

Find the probability that a person is a current smoker. b. Find a probability that a person has less than a high school diploma. c. Find a probability that a person is a current smoker and has less than a high school diploma. d. Find the probability that a person is a current smoker, given that the person has less than a high school diploma. e. Are the events current smoker and less than a high school diploma independent events?arrow_forwardUse this data for the exercises that follow: In 2013, there were roughly 317 million citizens in the United States, and about 40 million were elderly (aged 65 and over).[34] 60. It is predicted that by 2030, one in five U.S. citizens will be elderly. How much greater will the chances of meeting an elderly person be at that time? What policy changes do you foresee if these statistics hold true?arrow_forward
