Answer:
The answer is D.) Choosing New York as a sample, then selecting a sample of zip codes within New York, then sampling the names of people living in those zip codes.
Explanation:
When you use multistage sampling, you take a sample from a population by breaking it down into smaller and smaller groupings (units) at each stage. It's frequently used in nationwide surveys to collect data from a big, geographically dispersed group of people. I hope I helped! ^-^
Answer:
![y = \frac{2}{z} - \frac{x}{z}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B2%7D%7Bz%7D%20-%20%5Cfrac%7Bx%7D%7Bz%7D)
Step-by-step explanation:
Given
![x + zy = 2](https://tex.z-dn.net/?f=x%20%2B%20zy%20%3D%202)
Required
Rewrite to show y-intercept
We have: ![x + zy = 2](https://tex.z-dn.net/?f=x%20%2B%20zy%20%3D%202)
Subtract x from both sides
![zy = 2-x](https://tex.z-dn.net/?f=zy%20%3D%202-x)
Divide both sides by z
![y = \frac{2}{z} - \frac{x}{z}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B2%7D%7Bz%7D%20-%20%5Cfrac%7Bx%7D%7Bz%7D)

Answer:
- table: 14, 16, 18
- equation: P = 2n +12
Step-by-step explanation:
Perimeter values will be ...
rectangles . . . perimeter
1 . . . 14
2 . . . 16
3 . . . 18
__
The perimeter of a figure is twice the sum of the length and width. Here, the length is a constant 6. The width is n, the number of rectangles. So, the perimeter is ...
P = 2(6 +n) = 12 +2n
Your equation is ...
P = 2n +12 . . . . . . . . perimeter P of figure with n rectangles.
_____
<em>Additional comment</em>
You may be expected to write the equation using y and x for the perimeter and the number of rectangles. That would be ...
y = 2x +12 . . . . . . . . . perimeter y of figure with x rectangles

Answer: 35.54 degrees</h3>
How I got this answer:
tan(angle) = opposite/adjacent
tan(A) = BC/AC
tan(A) = 5/7
A = arctan(5/7) .... apply the inverse tangent, same as arctangent
A = 35.5376778 ... make sure your calculator is in degree mode
A = 35.54 .... rounding to two decimal places
