For each of the following sampling situations, identify the population as exactly as possible. That is, say what kind of individuals the population consists of and say exactly which individuals fall in the population. If the information given is not complete, complete the description of the population in a reasonable way.

a. A college has changed its core curriculum and wants to obtain detailed feedback information from the students during each of the first 12 weeks of the coming semester. Each week, a random sample of 5 students will be selected to be interviewed.
b. The American Community Survey (ACS) will replace the census "long form" starting with the 2010 census. The main part of the ACS contacts 250,000 addresses by mail each month, with follow-up by phone and in person if there is no response. Each household answers questions about their housing, economic, and social status.

c. An opinion poll contacts 1161 adults and asks them, "Which political party do you think has better ideas for leading the country in the twenty-first century?"

Answers

Answer 1

Here are the options that complete the questions;

For question 1. (a):

A) The population is all current students.

B) The population is students in the college during the first 12 weeks of the coming semester.

C) The population is the 60 students selected during the first 12 weeks of the coming semester.

D) The population is students in the coming semester.

For question 2. (b):

A) The population is 250,000 households.

B) The population is all U.S. households.

C) The population is all households that are being contacted by the ACS.

D) The population is U.S. households in 2010.

For question 3. (c):

A) The population is 1161 U.S. adults that supply information.

B) The population is all adult residents of the U.S.

C) The population is political parties.

D) None of the above.

Answer:

For question 1. (a) = B) The population is students in the college during the first 12 weeks of the coming semester.

For question 2. (b): = D) The population is U.S. households in 2010.

For question 3. (c): = B) The population is all adult residents of the U.S.

Explanation:

a) We can conclude that the research population would consist of students in the college during the first 12 weeks of the coming semester because students that failed to register for the 12 weeks of the coming semester are would not be counted in the random sample selection process.

b) The American Community Survey (ACS) as the name implies serves the entire American community; thus the population of the census is all U.S. households in 2010.

c) Although 1161 adults are been contacted, they do not represent the entire population, but just a sample out of all adult residents of the U.S.

[tex](x - 4) {}^{2} + (y - 3) {}^{2} = 5 {}^{2} [/tex]

The equation of the circle centered at point (4, 3) with a radius of length 5 is (x - 4)² + (y - 3)² = 5².

What is the equation of the circle with the given parameters?

The standard form equation of a circle with center (h, k) and radius r is:

( x - h )² + ( y - k )² = r²

Given that circle has a center at point (4, 3 ).

Hence:

h = 4

and k = 3

Also given that, the radius has a length of 5

r = 5

Plug these values into the above formula and simplify the equation:

( x - h )² + ( y - k )² = r²

( x - 4 )² + ( y - 3 )² = 5²

Expanding and simplifying, we get:

(x - 4)² + (y - 3)² = 25.

Therefore, the equation of the circle is (x - 4)² + (y - 3)² = 5².

Option D)  (x - 4)² + (y - 3)² = 5² is the correct answer.

Answers

Answer:

x = 3 , y = 1

Step-by-step explanation:

2x + y = 7

3x + y = 8

solution

2x + y = 7-----------(1)

3x - y = 8------------(2)

from equation 1

2x + y = 7

y = 7 - 2x-------------(3)

substitute equation 3 into equation 2

3x - y = 8

3x - (7 - 2x) = 8

3x - 7 + 2x = 8

3x + 2x = 8 + 7

5x = 15

divide through by the coefficient of x

5x/5 = 15/5

x = 3

to find y

substitute x into equation 1

2x + y = 7

2(3) + y = 7

Determine whether the equations are parallel or not for y= 3x-2 and y= 1/3x -11

Answers

Answer:

To know if these lines are parallel, you just have to look at the slope. In this case they are not.

Step-by-step explanation:

The slope is the number in front of your x. So for the first formula the slope is 3 and for the second one it is 1/3. The slope tells you in which direction the line goes, so if they are the same, that means that the lines are parallel. In this case the slopes are not the same, so the lines are not parallel.

Answer:

not parallel

Step-by-step explanation:

while the lines have a different y-intercept they do not have the same slope which they would need to be parallel. With two different slopes the lines will eventually cross.

Answers:

[tex]\displaystyle \lim_{x \to 2^{+}} f(x) = 1\\\\\displaystyle \lim_{x \to 2^{-}} f(x) = 1\\[/tex]

Both result in the same limit value. This allows us to say [tex]\displaystyle \lim_{x \to 2} f(x) = 1[/tex] without the plus or minus over the 2.

The left and right hand limits may not always match like this.

==================================================

Explanation:

The notation [tex]\displaystyle \lim_{x \to 2^{+}} f(x)[/tex] means that we are approaching x = 2 from the right hand side. This is from the positive direction. So we start at say x = 3 and move to x = 2.5 then to x = 2.1 then to x = 2.01 and so on.

Because we started with values x > 2, we will use the third definition of the piecewise function

if x > 2, then f(x) = 3x-5

Plug in x = 2 to get

f(x) = 3x-5

f(2) = 3(2)-5

f(2) = 6-5

f(2) = 1

This shows [tex]\displaystyle \lim_{x \to 2^{+}} f(x) = 1[/tex]

-----------------------------

For the other limit, we're approaching x = 2 from the negative side. So we could start at say x = 0, then move to x = 1, then to x = 1.5 then to x = 1.9 then to x = 1.99, and so on.

We're using x values such that x < 2 now.

So we'll be using the first definition of the piecewise function

If x < 2, then f(x) = x^2 - 3

f(x) = x^2-3

f(2) = 2^2-3

f(2) = 4-3

f(2) = 1

We end up with [tex]\displaystyle \lim_{x \to 2^{-}} f(x) = 1[/tex]

---------------------------------

Both right hand limit and left hand limit result in the same value

Because [tex]\displaystyle \lim_{x \to 2^{+}} f(x) = \displaystyle \lim_{x \to 2^{-}} f(x) = 1[/tex]

We can shorten that to [tex]\displaystyle \lim_{x \to 2^{}} f(x) = 1[/tex] meaning we can approach x = 2 from either direction to arrive at the same limiting value.

A thing to notice is that f(2) is not equal to 1. Instead the second line of the piecewise function says f(2) = 3.

The fact that the limit as x approaches 2 and f(2) don't agree means this function is not continuous at x = 2.

The graph shows this. We have a removable discontinuity where we effectively picked the point off the graph and move it upward.

For both categories of departing passengers, there are experienced passengers and inexperienced passengers. The experienced passengers typically do not require much interaction with check-in agents, as they are comfortable using online check-in systems or the automated kiosk systems. The inexperienced passengers typically interact with the check-in agents. Research shows that the experienced bago departing passengers check-in online and do not interact with the agents, and neither do they use the kiosk systems. However, the inexperienced bago passengers use the kiosk systems, typically spending 4 minutes to complete check-in. The inexperienced bago passengers do not interact with the check-in agents. Research also shows that the experienced international departing passengers must visit with the check-in agents to verify their travelling documents. Typically, each of these passengers spend 6 minutes with the check-in agent, and do not utilize the online check-in or automated kiosk systems. Lastly, the inexperienced international departing passengers interact with the check-in agents to verify their travelling documents and to get answers to any questions regarding their flights. These interactions last 10 minutes with the check-in agents. There is no need for these passengers to use the online check-in or the automated kiosk systems. Once passengers have checked in, they must go through security clearance, which takes 1 minute. Security clearance is required for all categories of passengers.

Illustrate the demand and supply represented by the equations above and the equilibrium on one graph with Q on the horizontal axis and P on the vertical axis. .Find the area of the region that lies under the parabola y=5x - x^2, where 1x4. True, False or Uncertain(Please explain):The demand for gasoline rises. Within a week, the price of a gallon of gasoline rises from $2 to $4. T/F/U: After a few years, the price will be more than $2 but less than $4. (You may assume that there are no further changes in demand or supply in the long run.) Two point charges, with charge magnitudes q and ????, are placed a distance r apart. In this arrangement, each point charge experiences a force of magnitude F. In the three scenarios, q, ????, and r are changed to some multiple of their original values. In each case, fill in the missing value on one of the variables that will result in a force between the point charges that is equal in magnitude to the original F.Original q Q rScenario 1 2q ...Q 4rScenario 2 ...q 2Q (1/2)rScenario 3 (3/2)q (3/8)Q ...r
