Answer:
1. The population of interest is all city goverments in the U.S.
5. The parameter of interest is the proportion of the city goverments in the U.S. that provide electricity to their residents.
Step-by-step explanation:
Hello!
Missing questions:
Which of the following is true? Select all that apply.
- The population of interest is all city governments in the U.S.
- The population of interest is the 192 cities.
- The population of interest is all city governments that provide utilities to their residents.
- The population of interest is 6.25%
- The parameter of interest is the proportion of the city governments in the U.S. that provide electricity to their residents.
- The parameter of interest is 6.25%
- The population of interest is the 20 counties.
- The parameter of interest is the list of all counties in the U.S.
The objective of this essay is to test utilities provided by city governments, for this a sample of 20 counties was taken then contacted each city of them counting how many of them provided utilities to their residents, finding out that 12 out of 192 cities (6.25%) provided electricity to their residents.
The study variable is:
X: Number of city governments that provide utilities (electricity) to their residents, in a sample of 192.
The population of the study is the city governments in the U.S.
And the parameter of interest is the population proportion of city governments in the U.S. that provide electricity to their residents.
I hope it helps!
The company needs 41 labels on average, each minute.
<h3>What is the circumference of a
circle?</h3>
The perimeter of a circle (circumference): 2 π radius
Replacing with the values given:
C = 2 (3.14) 2 = 12.56 cm
So, the area of one label is:
Area of a rectangle: length x width = 12.56 x 7 = 87.92 cm sq.
Now, the number of label be n
87.92 x n = 3612.64 cm2
n = 3612.64 / 87.92
n = 41.09
Hence, The company needs 41 labels on average, each minute.

6000N
reason: according to Newton’s second law of motion, Force = Mass x Acceleration
using this, multiply 2000 by 3 to get 6000
Given the sequence:
6, 10, 14, 18,...
We will find the 75th term
The given sequence is an arithmetic sequence
Because there is a constant common differnce
d = 18 - 14 = 14 - 10 = 10 - 6 = 4
The first term = a = 6
The general formula of the arithmetic sequence is as follows:
Where: n is the nth term
To find the 75th term, substitute with n = 75 and a = 6, d = 4
So, the answer will be the 75th term = 302
A point that bisects a segment would be its midpoint. This is a case where the vocabulary (bisect as opposed to midpoint) makes it harder.
To find the midpoint, we use the midpoint formula. The midpoint formula is:
midpoint = (x₁ + x₂/2, y₁ + y/2). To find it, you add the x coordinates and then divide them by 2. Repeat for the y coordinates.
x: (-2 + 6)/2 = 4/2 = 2
y: (5 +1)/2 = 6/2 = 3
Thus the point B bisecting AC is at (2, 3).
