The population of the country is increasing at 100%.
In this question,
The Population Growth (PG) we find the difference (subtract) between the initial population and the population at time 1, then divide by the initial population and multiply by 100.
Population of the country at present = 170 million
Population of the country 85 years later = 340 million
Percentage of population growth =
(future population - present population) / present population × 100
⇒
⇒
⇒ 100 %
Hence we can conclude that the population of the country is increasing at 100%.

Given Information:
Population size = N = 210
Mean height of women population = μ = 64.4 in.
Standard deviation of height of women population = σ = 2.9 in.
Sample size = n = 36
Required Information:
Sample mean = μx = ?
Sample standard deviation = σx = ?
Answer:
Sample mean = μx = 64.4 in.
Sample standard deviation = σx = 0.44 in.
Step-by-step explanation:
We are given a Normal Distribution, which is a continuous probability distribution and is symmetrical around the mean. The shape of this distribution is like a bell curve and most of the data is clustered around the mean. The area under this bell shaped curve represents the probability.
The mean of the sample will be same as population mean that is
μ = μx = 64.4 in
Whereas the sample standard deviation is given by
Where σ is the standard deviation of height of women population, N is the population size and n is the sample size.
The term is known as finite population correction factor and is used since the sampling is done without replacement.
Therefore, the standard deviation of sample is 0.44 in.
I'd say that they are all equivalent because when you divided all of them it equals each other.
2:6 = 1/3
3:9 = 1/3
4:12 = 1/3
Answer:
= 11x + 2
Step-by-step explanation:
2(x+1)+9x
Distributive property
= 2x + 2 + 9x
Simplifying
= 11x + 2
