Answer:
Step-by-step explanation:
The sampling method employed in the given example is convenience sampling.
Convenience sampling is a non-probability sampling technique where the sample is selected based on its accessibility and convenience. In this case, the post office manager selected three delivery people from the total of 11 available. This selection was based on convenience, as they were already working for the post office.
The population in this scenario consists of all the customers the post office manager works with. Let's denote this population as N.
The post office manager used convenience sampling to select a subset of the population to participate in the study. The size of the sample is not explicitly mentioned, but we can assume it is the total number of customers on the three selected delivery routes. Let's denote the sample size as n.
Since convenience sampling does not involve random selection, the sample selected may not be representative of the entire population. The customers on the selected delivery routes may not be a fair representation of all the post office customers. This introduces a potential sampling bias.
It's important to note that convenience sampling can be quick and easy to implement but may not provide reliable or generalizable results. In this case, the post office manager may obtain information about customer satisfaction from a limited group, potentially leading to skewed or unrepresentative findings. For a more accurate and representative study, a different sampling method, such as random sampling or stratified sampling, could be employed.

For all of the graphs:
Start the point on the number that I got from the inequality.
A filled circle means:
Greater than or equal to or less than or equal depending on where the line goes.
A hallow circle means:
Greater than or less than also depending on where the line is pointed towards too.
In order to graph an inequality you have to find and simply first then graph it.
For example on number 1, K ≤ -4.
Let's graph!
As you can see I filled in the circle and started at the point, -4.
Once I did it I made it bold from -4 and there on to the left. Making -4 be greater than or equal to K.
I showed that -4 is greater than or equal to K by making the line bold behind -4, also by filling in the circle.

There are 24 girls in a class. The ratio of girls to boys is 3:8.
How many boys are in the class?
Answer:
64 boys.
Step-by-step explanation:
There are 3 girls for every 8 boys.
24/3 = 8
8 * 8 = 64
The number of boys will be [tex]64[/tex] .
What is ratio ?Ratio is the comparison of two numbers i.e. how much a number contains other.
We have,
Number of girls [tex]=24[/tex]
Ratio of girls to boys [tex]=\ 3:8[/tex]
So,
According to the question,
Let number of girls [tex]=3x[/tex]
Number of boys [tex]=8x[/tex]
And,
We have number of girls so compare them,
i.e. [tex]3x=24[/tex]
⇒[tex]x= 8[/tex]
So, now putting value of [tex]x[/tex] in Number of boys,
i.e.
Number of boys [tex]=8x[/tex]
[tex]=8*8[/tex]
Number of boys [tex]=64[/tex]
Hence, we can say that the number of boys will be [tex]64[/tex] .

Match each event to the likelihood of its occurrence. rolling a six-sided die and getting a 7 randomly selecting a girl from a team of 14 boys and 4 girls randomly selecting a short straw from a set of 12 short straws and 12 long straws picking a bird from a list of 20 bird species and 6 other animals likely arrowRight impossible arrowRight unlikely arrowRight neither likely nor unlikely arrowRight
A six sided die has numbers 1 through 6 so getting a 7 is impossible so the probability would be 0 (impossible)
14 + 4 = 18 total boys and girls
Picking a girl would be 1/18 this is low so ( unlikely)
12 short and 12 long straws = 24 total straws. Picking a short one would be 12/24 = 1/2 this is in the middle ( neither likely nor unlikely)
20 + 6 = 26 total animals
Picking a bird = 20/26 = 10/13, this is high ( likely)

Answer:
is it asking which one is a y coordinate?
Answer:
Q'(5, -3), R'(4, -1), S'(0, -2), T'(0, -5)
Step-by-step explanation:
Reflecting across the y-axis causes the x coordinate of a point to change to its opposite. So in terms of x and y: (x, y) ⇒ (-x, y)
Q(-5, -3) ⇒ Q'(5, -3)
R(-4, -1) ⇒ R'(4, -1)
S(0, -2) ⇒ S'(0, -2)
T(0, -5) ⇒ T'(0, -5)
