Answer:
The population in 2003 was 234 million
Step-by-step explanation:
In order to calculate the population in 2003 we would have to use the The exponential growth formula as follows:
p(y)=ir^t
According to the given data:
p(y)=233 million
i=231 million
t
=1999-1991
Therefore, 233 million=231 million r^(1999-1991)
(233 million/231 million)^(1/8)=r
p(y)=231 million(233 million/231 million)^((y-1991)/8)
Therefore, in 2003
p(2003)=231 million(233 million/231 million)^((2003-1991)/8)
p(2003)=231 million(233 million/231 million)^(1.5)
p(2003)=234 million
The population in 2003 was 234 million
Answer:
let the number be y
4(y-7)=48
y-7=48/4
y-7=12
y=12+7=19
I would appreciate if my answer is chosen as a brainliest answer
Answer:
3/7
Step-by-step explanation:
Use Y2-Y1/X2-X1
So, 7+2/7+14=9/21
9/21 can be simplified so divide both by 3 which leaves you with 3/7
3×1=3+3=6 and that your answers
