Answer:
The solution set is the empty set.
Step-by-step explanation:
{x | x < 2} is the set of all numbers less than 2. This means x can take values such as 1.99, 0, -2000 and so on. That is, all values less than 2.
{x | x ≥ 2} is the set of all numbers equal to or greater than 2. This means x can take values such as 2, 2.1, 5000, and so on. That is, 2 or any value greater than 2.
Since there is no sign between the two sets, the question is asking for the intersection between these two sets. That is, what elements are common to these two sets? As we can see, the two sets don't have any common element. Hence, their intersection is the empty set.
(Note that the union of these two sets would be the set of all real numbers as that includes all elements from either set).
Answer:
The population in the study are those male university graduates who have a white collar job.
Step-by-step explanation:
This is a common statistics practice, when we want to study something from a population, we find a sample of this population.
For example:
I want to estimate the proportion of New York state residents who are Buffalo Bills fans. So i ask, lets say, 1000 randomly selected New York state residents wheter they are Buffalo Bills fans, and expand this to the entire population of New York State residents.
In this problem, we have that:
Sample of 1172 male university graduates who have a white collar job and asks whether or not they had received a raise atnbsp work nbspduring the past 4 months.
What is the population in the study?
The sample is of male university graduates who have a white collar job.
So the population in the study are those male university graduates who have a white collar job.
5-7 = -2 and 1-6= -5 so the slope would be 2/5. you would set it up like this:
y=2/5x and then your y-intercept
<span>16/20 is 80%.</span>
You find out by multiplying the denominator: 20 * 5 = 100
Then, you do the same to the numerator which is: 16 * 5 = x
So, x = 80%
Hope this helps! :D
