Answer:
112,547.095 million
Step-by-step explanation:
Data provided in the question
Population of a city in 2005 = 18,000
In the year 2010, the city population = 45,000
Now to find out the projected population for 2015 we use the exponential model
where
P(0) = Initial population
r = growth rate
t = time
e = natural log
So,
So
r ≈ 0.1833
Now
= 112,547.095 million
Answer:
The critical values are -1.96 and 1.96.
Step-by-step explanation:
The test is a two-tailed test because the alternate hypothesis (Ha) is expressed using not equal to.
To find the critical values for a two-tailed test, divide the significance level by 2 (0.05/2 = 0.025)
The critical values at z0.025 are -1.96 and 1.96
The equations classified according to the number of solutions are given as follows:
- No solution: -3(3q + 4) = -6q + 12
- One solution: -2(3n - 4) = -6n - 4
- Infinitely many solutions: 8z - 4 = 8z - 4
<h3>How many solutions does the equation 4(2z - 1) = 8z - 4 has?</h3>
We solve the equation, hence:
4(2z - 1) = 8z - 4
8z - 4 = 8z - 4
Equivalent, hence they have infinitely many solutions.
<h3>How many solutions does the equation -2(3n - 4) = -6n - 4 has?</h3>
-2(3n - 4) = -6n - 4
-6n + 8 = -6n - 4
0 = -12, which is false, hence it has no solutions.
<h3>How many solutions does the equation -3(3q + 4) = -6q - 12 has?</h3>
-3(3q + 4) = -6q + 12
-9q - 12 = -6q + 12
3q = -24
q = -8.
One solution.
