The answer is 150 million.
Step 1. Calculate the growth rate.
Step 2. Calculate the population number in 2014.
We will use the formula for exponential growth:
A = P * eⁿˣ
where:
A - the final amount (value)
P - the initial amount (value)
e - the mathematical constant (e ≈ 2.72)
n - the growth rate
x - the time
Step 1:
A = 141 million = 141 000 000
P = 136 million = 136 000 000
n = ?
x = 2000 - 1991 = 9
Therefore:
Logarithm both sides of the equation:
Step 2:
Now when we know the growth rate, it is easy to estimate the population in 2016
A = ?
P = 141 000 000
n = 0.004
t = 2016 - 2000 = 16
Thus, the population will be nearly 150 million in 2016

Answer:
Option C. the volume of water in the tank is decreasing by 0.4L per hour
Step-by-step explanation:
step 1
Find the slope
we know that
The formula to calculate the slope between two points is equal to
we have
Substitute the values
The slope is negative
so
is decreasing
That means------> the volume of water in the tank is decreasing by 0.4L per hour
