Answer:
y=1.7x-1.2
Step-by-step explanation:
-10x-17y=14
Subtract 10x to both sides
-17y=-10x+14
Divide by -17 on both sides
y=1.7x-1.2

The person above me answered it correctly, I basically just copied and pasted it onto here :)
Options A and E are categorical.
Is your job as an IT administrator stressful?
Have you ever considered switching careers because of on-the-job stress?
Given,
- Is your job as an IT administrator stressful?
- What is your biggest source of stress?
- How has your job impacted your personal life?
- In the past week, how many hours of overtime did you work?
- Have you ever considered switching careers because of on-the-job stress?
We need to find which options are categorical.
What are categorical data?The data that can be divided into groups are called categorical data.
Example:
People who know how to drive and who don't know how to drive.
We can have two groups here.
Yes and No.
Find which of the following are categorical.
- Is your job as an IT administrator stressful?
We can have two groups:
Yes and No.
It is categorical data.
- What is your biggest source of stress?
We can have different answers which can not be categorized into groups.
It is not categorical data.
- How has your job impacted your personal life?
Everyone will have different answers so it is not categorical data.
- In the past week, how many hours of overtime did you work?
Everyone will have a different answer so we can not make groups.
It is not categorical data.
- Have you ever considered switching careers because of on-the-job stress?
We can have answers as yes and no so we can make two groups
It is categorical data.
Thus Options A and E are categorical.

What is the perimeter of polygon LMNPQ
Answer: c for maps
Step-by-step explanation:
17.66 units is the perimeter of the polygon.
What is Perimeter?The perimeter of a two-dimensional form is the space surrounding it. It represents the total length of the shape's sides. The units used to measure the sides of the form, such as meters, centimeters, inches, or feet, determine the units used to measure the perimeter.
To find the perimeter of the polygon LMNPQ, we need to add up the lengths of all the sides.
The distance formula for finding the distance between two points [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] is:
[tex]d = \sqrt{(x_2 - x_1)^2 + (y-2 - y-1)^2)[/tex]
Using this formula, we can find the lengths of each side of the polygon:
[tex]LM = \sqrt{(2 - 4)^2 + (4 - 2)^2} = \sqrt{8}\\MN = \sqrt{(5 - 2)^2 + (8 - 4)^2} = \sqrt{25}\\NP = \sqrt{(8 - 5)^2 + (4 - 8)^2}= \sqrt{25}\\PQ = \sqrt{(6 - 8)^2 + (2 - 4)^2} = \sqrt{8}\\QL = \sqrt{(4 - 6)^2 + (2 - 2)^2} = 2[/tex]
Therefore, the perimeter of the polygon LMNPQ is:
Perimeter = LM + MN + NP + PQ + QL
= √8 + √25 + √25 + √8 + 2
≈ 2.83 + 5 + 5 + 2.83 + 2
≈ 17.66
So, the perimeter of the polygon LMNPQ is approximately 17.66 units.

If Aaron tunes into his favorite radio station at a randomly selected time, there is a 0.20 probability that a commercial will be playing.
b. If Aaron tunes into this station at 5 randomly selected times, will there be exactly one time when a commercial is playing?
Answer:
Yes, there will be with a probability of 0.4096
Step-by-step explanation:
Given,
p = 0.2
1 - p = 0.8
Number of trials, n = 5
P(x = 1)
Using the binomial probability formula :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
P(x = 1) = 5C1 * 0.2^1 * 0.8^4
P(x = 1) = 5 * 0.2^1 * 0.8^4
P(x = 1) = 0.4096
Yes, there will be with a probability of 0.4096
Answer:
No. If Aaron tunes into this station at 5 randomly selected times, there will not necessarily be exactly one time when a commercial is playing.

i have another question, whats 16 divided by 6,720?
Answer: 0.00238095238
Step-by-step explanation:
if 50% is 7 what is 25%, 75%, and 100%
Answer:
100% = 14
75% = 10.5
25% = 3.5
Answer:
100% = 1475% = 10 1/250% = 725% = 3 1/2Step-by-step explanation:
50% if a number is also 1/2 of that number. So, we multiply 7 by 2 to get 14.
Now we know that we need to solve for 25%, 75%, and 100% of 14.
100% of a number is just that number, so 100% of 14 is 14.
To solve for 75% of 14, we multiply 3/4 by 14.
3/4 x 14/1 = 42/4 = 10 1/2
The final number to solve for is 25% of 14.
1/4 x 14/1 = 14/4 = 3 1/2
