The fundamental difference between a sample survey with nonresponse and a volunteer sample is the way participants are selected and the biases that may result from each approach. While nonresponse in a sample survey can lead to nonresponse bias, volunteer samples are more susceptible to selection bias.

The fundamental difference between a sample survey of human beings that may suffer from nonresponse and data using a volunteer sample is the way participants are selected and the potential biases that may arise.
In a sample survey, a random selection of individuals is chosen from the target population. However, nonresponse can occur when some of these selected individuals fail to participate or provide incomplete information. This can lead to nonresponse bias, which affects the representativeness of the sample and the accuracy of the results. To minimize nonresponse bias, researchers should ensure that their survey design and data collection methods encourage participation and provide clear instructions for respondents.
On the other hand, a volunteer sample consists of participants who willingly choose to participate in the study, usually in response to an open invitation. This approach is more prone to selection bias, as the individuals who volunteer may not be representative of the target population. They may have certain characteristics or attitudes that motivated them to participate, leading to biased results that may not generalize to the broader population. To address selection bias, researchers should carefully consider the recruitment method and the potential impact of volunteerism on their findings.
In summary, the fundamental difference between a sample survey with nonresponse and a volunteer sample is the way participants are selected and the biases that may result from each approach. While nonresponse in a sample survey can lead to nonresponse bias, volunteer samples are more susceptible to selection bias. Researchers must be mindful of these biases when designing and conducting their studies.

Answer:

The statement that is true about the given equation is that it has no solution. This can be seen by rearranging the terms on both sides of the equation and then solving for y. When we do this, we get:

3(-y + 7) = 3(y + 5) + 6

-3y + 21 = 3y + 15 + 6

-6y = -12

y = 2

However, when we substitute this value of y back into the original equation, we find that it does not satisfy the equation. This means that there is no value of y that can make the equation true, so the equation has no solution.

Step-by-step explanation:

If two side lengths of a fence are 9 and 12 inches and the sum of the three lengths ranges from 31 to 40 inches, then the length of the third side, x,  can be presented by the compound inequality 10 ≤ x ≤ 19.

Inequality refers to the relationship between two non-equal expressions. It can be denoted by > for greater than, < for less than, ≥ for greater than and equal to, and ≤ for less than and equal to.

Given that the sum of the three lengths of a fence ranges from 31 to 40 inches, the inequality can be written as:

\(31 \leq \text{sum} \leq 40\)

If two side lengths are 9 and 12 inches, and let x be the third length, the inequality becomes:

\(31 \leq 9 + 12 + x \leq 40\)

\(31 \leq 21 + x \leq 40\)

Subtracting 21 at all sides,

\(31 - 21 \leq 21 + x - 21 \leq 40 - 21\)

\(\bold{10 \leq x \leq 19}\)

Hence, the compound inequality to show the length of the third side can be written as 10 ≤ x ≤ 19.

Step-by-step explanation:

It is valid to suggest that fewer than half of Americans prefer to watch the news rather than read or listen to it.

Testing for the claim that fewer than half of A.m.e.r.i.c.a.n.s. prefer to watch the news rather than read or listen to it, we can use a one-tailed, lower-bound z-test for proportions. The null hypothesis is that the proportion of Americans who prefer to watch the news is greater than or equal to 0.5, and the alternative hypothesis is that the proportion is less than 0.5.

Using the normal approximation to the binomial distribution, the z-score is calculated as:

z = (P - 0.5) / (√(p*(1-p)) / √(n))

where P is the sample proportion (46.9%), p is the population proportion (0.5), and n is the sample size (1009).

The p-value is the probability of getting a z-score as extreme or more extreme than the one calculated, assuming the null hypothesis is true.

z = (0.469 - 0.5) / (√(0.5*(1-0.5)) / √(1009)) = -2.2

The p-value is calculated by looking up the z-score of -2.2 in a standard normal table and finding the probability in the lower tail. The p-value is approximately 0.0135

Since the p-value (0.0135) is less than the significance level (0.05), we r.e.j.e.c.t. the null hypothesis and conclude that it is true to suggest that fewer than half of A.m.e.r.i.c.a.n.s. prefer to watch the news rather than read or listen to it.

The inverse Laplace transformations of the given functions are 1. \(f(t) = -e^t + e^{3t}\) and 2. \(f(t) = -e^{4t} + e^{(-2t)}.\)

To find the inverse Laplace transformations of the given functions, we will use partial fraction decomposition and the table of Laplace transforms.

1. For\(F(s) = ((s-2)e^{-s})/(s^2-4s+3):\)

First, we factor the denominator as (s-1)(s-3). Therefore, we can write F(s) as:

\(F(s) = ((s-2)e^{-s})/((s-1)(s-3))\)

Using partial fraction decomposition, we can express F(s) as:

F(s) = A/(s-1) + B/(s-3)

Multiplying both sides by (s-1)(s-3), we get:

(s-1)(s-3)F(s) = A(s-3) + B(s-1)

Next, we can substitute values of s to solve for A and B. Let's choose s = 1 and s = 3:

(s-1)(s-3)F(s) evaluated at s = 1: 0 = A(1-3) + B(1-1)

(s-1)(s-3)F(s) evaluated at s = 3: 0 = A(3-3) + B(3-1)

Simplifying the equations, we find A = -e and B = e.

Therefore, F(s) = (-e/(s-1)) + (e/(s-3))

Using the Laplace transform table, we find the inverse Laplace transformation of F(s):

\(f(t) = -e^t + e^{3t}\)

2. For\(F(s) = (2e^{(-2s))}/(s^2-4)\):

The denominator can be factored as (s+2)(s-2). Thus, we can express F(s) as:

\(F(s) = (2e^{(-2s)})/((s+2)(s-2))\)

Using partial fraction decomposition:

F(s) = A/(s+2) + B/(s-2)

Multiplying both sides by (s+2)(s-2), we get:

(s+2)(s-2)F(s) = A(s-2) + B(s+2)

Substituting s = -2 and s = 2 to solve for A and B:

(s+2)(s-2)F(s) evaluated at s = -2: 0 = A(-2-2) + B(-2+2)

(s+2)(s-2)F(s) evaluated at s = 2: 0 = A(2-2) + B(2+2)

Simplifying the equations, we find A = \(-e^4\) and B = \(e^{(-4)}\).

Therefore,\(F(s) = (-e^4/(s+2)) + (e^{(-4)}/(s-2))\)

Using the Laplace transform table, we find the inverse Laplace transformation of F(s):

\(f(t) = -e^{4t} + e^{(-2t)}.\)

Therefore, these are the inverse Laplace transformations of the given functions.

The production function m=min{s,l}, where s represents manicure supplies and l represents labor hours, is not homothetic.

To determine if a production function is homothetic, we need to examine whether scaling the inputs by a common factor affects the output in a consistent way. In this case, the production function m=min{s,l} implies that the quantity of manicures produced is determined by the minimum of the supplies and labor hours.

Suppose we scale the inputs by a common factor k>0. If s and l are multiplied by k, the new inputs become ks and kl respectively. Now, let's consider the case where s>l initially. The production function will be m=min{ks,kl}=kl, as ks is larger than kl. However, if we scale both inputs by k, the new production function will be

\(m = min\{k^2s,k^2l\}=k^2l\). Since \(k^2l\) is not equal to kl, the production function is not homogeneous of degree one and therefore not homothetic.

In conclusion, the production function m=min{s,l} is not homothetic because scaling the inputs by a common factor does not result in a consistent scaling of the output.

The amount borrowed at 3% was $498,980, the amount borrowed at 4% was $1000, and the amount borrowed at 5% was $20.

To solve this system using matrices, we can set up a matrix equation and use matrix operations to solve for the unknown amounts borrowed at each rate.

Let x = amount borrowed at 3%
y = amount borrowed at 4%
z = amount borrowed at 5%

The system of equations can be written as:

x + y + z = 500,000
0.03x + 0.04y + 0.05z = 20,500
y = 2.5x

We can write this system as a matrix equation:

[1 1 1] [x] = [500,000]
[0.03 0.04 0.05] [y] = [20,500]
[0 2.5 -1] [z] = [0]

We can use matrix operations to solve for x, y, and z. First, we can use row operations to get the matrix in reduced row echelon form:

[1 1 1] [x] = [500,000]
[0 1 -25] [y] = [500]
[0 0 62.5] [z] = [1250]

Then, we can solve for z by dividing the third equation by 62.5:

z = 1250/62.5 = 20

Next, we can substitute z back into the second equation to solve for y:

y - 25(20) = 500
y = 500 + 500 = 1000

Finally, we can substitute y and z back into the first equation to solve for x:

x + 1000 + 20 = 500,000
x = 500,000 - 1020 = 498,980

Step-by-step explanation:

(f o g)(x) means to wad up g(x) and stuff it into the place of x in f(x).

(f o g)(x)

means f( g(x) )

Here's f(x)

f(x) = 5x - 4

If you were calculating f(2) you would put a 2 in place of x. Or f(18) you would put 18 in place of the x. In this case we will cram the entirety of

x²-3x - 11 into the place of x.

f(x) = 5x + 4

Let's make a lot of room for g(x).

f(x) = 5___x_____ + 4

Okay, here we go:

f(g(x))

= 5(x²-3x - 11) + 4

See how we replace the x in f(x) with the whole entire g(x).

Now we'll simplify because they asked for standard form.



f(g(x))

= 5(x²-3x - 11) + 4

Use distributive property.
