The domain of the graph is (0, 20)
<h3>How to find the domain of a graph?</h3>
The domain of a function is the set of all possible inputs for the function.
Domain are all the values that go into a function.
The domain of the graph are the values of the x coordinates.
The domain are called the input or independent variables.
The independent variable does not depend on any variable to get it values.
Therefore, the domain of the graph is (0, 20)

That is a very good question....
Look Grank
you know that:
confidence interval = mean +or- Margin of Error
and
Margin of Error = (z)*(standard deviation) / (sqrt of n)
where n is the number of sample records
So we need to calculate z-value firstly
It says: "<span>we want 90% confidence"
So that:
</span>
<span>confidence90% corresponds to z-value of 1.645
Plug that into our formula of </span><span>Margin of Error:
</span>Margin of Error = (1.645)*(22) / (sqrt of n)
"The sample mean is within 2.7 lb of the population mean" means that Margin of Error is 2.7
<span>Margin of Error:
</span>2.7 = (1.645)*(22) / (sqrt of n)
Now solve for n:
n=179.66~180
SO that 180<span> women must be randomly selected to estimate the mean weight of women in one age group.</span>
Answer:
If I could travel to any year in a time machine, I would choose a year in future. For example, 3050. Everyone assumes the future according to their own imagination. But nobody knows what it actually looks like. So, if I could time travel, I would travel to a year in future.
Answer:
10 times
Step-by-step explanation:
5 gallons = 20 quarts
20 quarts / 2 quarts = 10
When studying populations, it is very difficult to evaluate all individuals, whether by size, difficulty, budget, etc., to solve this, the statistical inference deals with all the mathematical procedures that allow drawing conclusions for the population, with a degree of calculable error, from a sample of it.
Answer
C. Is the process of drawing inferences about the population based on the information taken from the sample
