(a)
To find: The total population of males and females in 2021.
(a)

Answer to Problem 92CR
Total population of males and females in 2021 will be 333.4 million.
Explanation of Solution
Given data:
Function is:
Calculation:
Total population of males and females in 2021:
As t=10 is 2010; So t=21 is 2021
Conclusion:
Total population of males and females in 2021 will be 333.4 million.
(b)
To find: Year in which population was 320 millions.
(b)

Answer to Problem 92CR
2014 was having 320 million population.
Explanation of Solution
Given data:
Function is:
Calculation:
Year in which population reaches 320 million:
So the year was 2014 as the year 2021 was having 333.4 million population.
Conclusion:
2014 was having 320 million population.
