Answers
9514 1404 393
Answer:
-4.5
Step-by-step explanation:
The y-intercept can be found by setting x=0 and solving for y.
-2y = 9
y = -9/2 = -4.5 . . . the y-intercept

S-IC.2: Decide if a specified model is consistent with results from a given data-generating process, e.g., using simulation.
A drug manufacturer claims that 13% of the population of South Africa is living with HIV. As a World Health Organization researcher, you collect evidence to test this claim. You use statistical techniques to sample 125 random residents of South Africa and find that 20 of them test positive for HIV.
You plan to simulate one sample of 125 residents by randomly selecting 125 integers between 1 and 100.
From your actual sample of 125 residents, what proportion of the sample has HIV? 125
What do the randomly selected numbers represent? Why did you pick 125 of them? The number of residents
What assigned numbers indicate a simulated resident has HIV?
2. You plan to run 100 simulations, each with a random sample of 125 residents.
What do you think the true mean population proportion from the 100 simulations would be close to? Explain why.
Is this a simulation of an observational study or an experimental study? Explain why.
The margin of error for this study is about 0.06 or 6% around the population proportion. Are you able to support the claim of the drug manufacturer? Explain why or why not.
What could be done to make the margin of error smaller and get a better sample of the population? Why does that make sense?
Answers
Answer:
gooooooooooooooooo
Step-by-step explanation:
goooooooooooooooooop
1) The proportion of the sample that has HIV is 0.16. 2) The randomly selected numbers represent the HIV status of the simulated residents.
1. The proportion of the sample that has HIV is 20 / 125 = 0.16.
2. The randomly selected numbers represent the HIV status of the simulated residents. We picked 125 of them because that is the sample size of the actual study.
We can assign the numbers 1 to 13 to represent the simulated residents who have HIV. This is because 13% of the population is estimated to have HIV.
I think the true mean population proportion from the 100 simulations would be close to 0.13, the HIV prevalence rate that was estimated in the actual study. This is because the simulations are randomly generated, and the probability of a simulated resident having HIV is 13%.
This is a simulation of an observational study. This is because the researchers are not intervening in the lives of the simulated residents. They are simply observing the HIV status of the simulated residents.
The margin of error for this study is 0.06, which is 6%. This means that the true population proportion of people with HIV could be anywhere between 0.07 and 0.19. The drug manufacturer's claim that 13% of the population has HIV is within this range, so we cannot definitively support or refute their claim.
To make the margin of error smaller and get a better sample of the population, we could increase the sample size. This would give us more data points to work with, which would make our estimate of the population proportion more accurate. Additionally, we could stratify the sample by age, gender, or other factors that could affect the prevalence of HIV. This would help us to ensure that our sample is representative of the entire population.

Answers
Answer:
Option (3)
Step-by-step explanation:
Formula to get the surface area of a sphere is,
Surface area of a sphere = 4πr²
Here 'r' = Radius of a sphere
Since, r = 9 units and π = 3.14
Surface area of the sphere = 4(3.14)(9)²
= 1017.36 square ²units
Therefore, Option (3) will be the correct option.

X intercept: (-2,0)
Y intercept: (0,5)
Have a wonderful and blessed day!
Answer:
The x-intercept is 2.
The y-intercept is 5.
Step-by-step explanation:
The x-intercept is basically finding what the value of x when y is 0; y-intercept is vise-versa.
The format it is currently in is not in y=mx+b form which makes you unable to put on a graph...HOWEVER, YOU ACTUALLY CAN!
You goal for these type of questions is to isolate y by itself.
[tex]-20x+8y=40\\8y=20x+40\\y=2.5x+5[/tex]
Your equation has been converted into y=mx+b which now can be used to easily find the x and y intercepts.
You can either look at a graph and find the x and y intercepts or do it algebraically.
Since, "x-intercept is basically finding what the value of x when y is 0", we plug in y with 0.
Solve for X-Intercept:
[tex]0=2.5x+5\\-5=2.5x\\-2=x[/tex]
X-Intercept is -2
Solve for Y-intercept:
[tex]y=2.5(0)+5\\y=5[/tex]
Y-Intercept is 5

The second equation would become 8x - 8y = -28, and the 8y from the first equation and the -8y from the second would cancel out and you can solve for x.
