What is the world’s predicted population in the year 2020, rounded to the nearest million?
1 answer:
Answer:
B
Step-by-step explanation:
Given
P_0=5642000000 people
Growth Rate=i=1.3%
Since the years will be counted from 1994
So for 2020 population:
n=26 years
Using the formula,
P_n= P_0 e^in
Putting the values,
P_n=(5642000000)*(2.71828)^(0.013*26)
P_n=(5642000000)*1.40214
P_n= 7910874921.6228
Rounding off to nearest million
P_n= 7911000000 people
