Answer:

n = 3200

Step-by-step explanation:

200 = 1000 - \(\frac{n}{4}\) ( subtract 1000 from both sides )

- 800 = - \(\frac{n}{4}\) ( multiply both sides by 4 to clear the fraction )

- 3200 = - n ( multiply both sides by - 1 )

n = 3200

To prove that δqrev in equation 6.1 is not an exact differential, we can use the criterion developed in math chapter d. The criterion states that if a differential equation is exact, then its partial derivatives must satisfy the condition ∂M/∂y = ∂N/∂x.

In equation 6.1, δqrev is defined as δqrev = TdS. If we express δqrev in terms of its partial derivatives, we get:
∂(δqrev)/∂S = T
∂(δqrev)/∂T = S

Now, let's calculate the partial derivatives of ∂(∂(δqrev)/∂S)/∂T and ∂(∂(δqrev)/∂T)/∂S:
∂(∂(δqrev)/∂S)/∂T = ∂T/∂S = 0 (since T does not depend on S)
∂(∂(δqrev)/∂T)/∂S = ∂S/∂T = 0 (since S does not depend on T)

Since these partial derivatives are equal to zero, we can conclude that δqrev is not an exact differential, as it does not satisfy the condition ∂M/∂y = ∂N/∂x.

Therefore, we have proven that δqrev in equation 6.1 is not an exact differential.

The value of standard deviation of the sample is 11.29 grams.

To calculate the standard deviation of a sample, we need to use the following formula:

s = sqrt [ Σ(xi - x)^2 / (n-1) ]

where s is the standard deviation of the sample, Σ(xi - x)^2 is the sum of the squared deviations of each data point from the sample mean, n is the sample size and x is the sample mean

To calculate the standard deviation for the weights of the 5 mice, we first need to find the sample mean:

x = (56 + 59 + 78 + 56 + 77) / 5 = 65.2

Next, we can calculate the sum of the squared deviations:

Σ(xi - x)^2 = (56 - 65.2)^2 + (59 - 65.2)^2 + (78 - 65.2)^2 + (56 - 65.2)^2 + (77 - 65.2)^2

= 82.36 + 41.64 + 156.64 + 82.36 + 147.56

= 510.56

Finally, we can calculate the standard deviation:

s = sqrt [ Σ(xi - x)^2 / (n-1) ] = sqrt [ 510.56 / (5-1) ] = sqrt [ 127.64 ] = 11.29

Therefore, the standard deviation is 11.29 grams.

There are 3 cases to consider when determining horizontal asymptotes:

1) Case 1: if: degree of numerator < degree of denominator. then: horizontal asymptote: y = 0 (x-axis)

2) Case 2: if: degree of numerator = degree of denominator.

3) Case 3: if: degree of numerator > degree of denominator.

The standard deviation of a sampling distribution of sample means is often referred to as the standard error of the mean. In this case, with a standard deviation of 3.1 for the sampling distribution of sample means, the best interpretation is that it represents the variability or dispersion of the sample means around the population mean.

More specifically, it quantifies the average amount of deviation or spread that is expected between the sample means and the true population mean. In other words, it provides an estimate of the typical or expected error in using a sample mean as an estimate of the population mean.

Therefore, the standard deviation of 3.1 in the sampling distribution suggests that, on average, the sample means are expected to deviate from the true population mean by approximately 3.1 units.

because there is 180 degrees in a line. if 105 degrees is taken away from the line. then (180 - 105) is 75 degrees.

T A can be seen as a linear transformation from R^2 to R^3.

To find the range and codomain of the matrix transformation T A, we need to first determine the matrix T A . The matrix T A is obtained by multiplying the input vector x by A:

T A (x) = A x

Therefore, T A can be seen as a linear transformation from R^2 to R^3.

To determine the range of T A , we need to find all possible outputs of T A (x) for all possible inputs x. Since T A is a linear transformation, its range is simply the span of the columns of A. Therefore, we can find the range by computing the reduced row echelon form of A and finding the pivot columns:

A =  (\left[\begin{array}{cc}1 & 2 \ 1 & -2 \ 0 & 1\end{array}\right]) ~ (\left[\begin{array}{cc}1 & 0 \ 0 & 1 \ 0 & 0\end{array}\right])

The pivot columns are the first two columns of the identity matrix, so the range of T A is spanned by the first two columns of A. Therefore, the range of T A is the plane in R^3 spanned by the vectors [1, 1, 0] and [2, -2, 1].

To find the codomain of T A , we need to determine the dimension of the space that T A maps to. Since T A is a linear transformation from R^2 to R^3, its codomain is R^3.

If the functions were not linear, it would not make sense to talk about their range or codomain in this way. The concepts of range and codomain are meaningful only for linear transformations.

The number of possible codes depends on the number of keys on the keypad and can be calculated using factorial notation: n!, where n is the number of keys.

the keypad has a certain number of keys, and each key can be used only once in the code. This implies that the code length is equal to the number of keys on the keypad.

To calculate the number of possible codes, we can use the concept of permutations. In a permutation, the order of the elements matters, and repetition is not allowed.

If there are n keys on the keypad, the first key can be chosen in n ways. After selecting the first key, the second key can be chosen from the remaining (n-1) keys in (n-1) ways. Similarly, the third key can be chosen in (n-2) ways, and so on.

Therefore, the total number of possible codes is given by the product of these choices: n * (n-1) * (n-2) * ... * 2 * 1, which is equal to n factorial (n!).

For example, if the keypad has 4 keys, the number of possible codes would be 4 factorial (4!) = 4 × 3 × 2 × 1 = 24. So, there would be 24 different codes that can be entered using the available keys on the keypad.

3.25x -y = -0.75 --------(2)

From (2) we can make y the subject of the relation

y = 0.75+3.25x -------(3)

Input 0.75+3.25x into y in (1)

-4.5x -2(0.75+3.25x) = -12.5

-4.5x -1.5- 6.5x = -12.5

-4.5x -6.5x -1.5 = -12.5

-11x = -12.5 +1.5

-11x = -11

x = 11/11

x = 1

If x = 1,substitute 1 into x in (3)

y = 0.75+3.25x

y = 0.75 +3.25(1)

y = 0.75 +3.25

option c is correct that if the two events are mutually exclusive than they cannot be independent.

As, we know that "mutually exclusive events are those events that do not occur at the same time".

Mutually exclusive events do not share any sample points with each other, so they cannot occur at same time. Thus, if event A and event B are mutually exclusive, they are actually inextricably dependent on each other because A's existence reduces event B's probability to zero and vice-versa.

Therefore, two events with nonzero probabilities cannot be independent and mutually exclusive because if two events are mutually​ exclusive, then when one of them​ occurs, the probability of the other must be zero.

Hence, option c is correct that if the two events are mutually exclusive than they cannot be independent.

The value of x is approximately 2.8462° and the value of maN is 37°.

To find the value of x and maN, we need to use the given information. According to the question, maN is equal to (13x)°.
To solve for x, we can set up an equation:
maN = (13x)°
Now, since we know that maN is equal to 37°, we can substitute this value into the equation:
37° = (13x)°
To isolate x, we divide both sides of the equation by 13:
37° / 13 = (13x)° / 13
This simplifies to:
2.8462° ≈ x°
Therefore, the value of x is approximately 2.8462°.
Now, let's find the value of maN. We already know that maN is equal to (13x)°. Substituting the value of x that we just found, we get:
maN = (13 * 2.8462)°
Simplifying the multiplication:
maN = 37°

Answer:

\(\dfrac{dK}{dt}= \$ 1.08 \ \text{per week}\), the capital investment is decreasing.

Step-by-step explanation:

To find the rate at which capital investment is changing when output is kept constant, we need to differentiate the output function with respect to time, t, and solve for the rate of change of capital investment, dK/dt.

The given output function is:

\(Q = 90K^{2/3}L^{1/3}\)

To find the rate of change, we differentiate both sides of the equation with respect to time. First rearrange the equation.

\(Q = 90K^{2/3}L^{1/3}\\\\\\\Longrightarrow K^{2/3}=\dfrac{Q}{90L^{1/3}}\)

Now differentiating...

\(K^{2/3}=\dfrac{Q}{90L^{1/3}}\\\\\\\Longrightarrow 2/3 \times K^{-1/3} \times \dfrac{dK}{dt} = \dfrac{Q}{90L^{4/3}} \times -1/3 \times \dfrac{dL}{dt} \\\\\\\therefore \boxed{\dfrac{dK}{dt}=-\dfrac{Q}{180L^{4/3}K^{-1/3}} \times \dfrac{dL}{dt}}\)

Substitute in all our given values...

\(\dfrac{dK}{dt}=-\dfrac{Q}{180L^{4/3}K^{-1/3}} \times \dfrac{dL}{dt}\\\\\\\Longrightarrow \dfrac{dK}{dt}=-\dfrac{90K^{2/3}L^{1/3}}{180L^{4/3}K^{-1/3}} \times \dfrac{dL}{dt}\\\\\\\Longrightarrow \dfrac{dK}{dt}=-\dfrac{K}{2L} \times \dfrac{dL}{dt}\\\\\\\Longrightarrow \dfrac{dK}{dt}=-\dfrac{27}{2(1000)} \times 80\\\\\\ \therefore\boxed{\boxed{\dfrac{dK}{dt}=-\dfrac{27}{25}\approx -1.08}}\)

Thus, the capital investment is decreasing at a rate of $1.08 per week.

The estimated current total cost for the installed and insulated tank is $12,065.73.

The first step is to calculate the surface area of the tank. The surface area of a cylinder is calculated as follows:

surface_area = 2 * pi * r * h + 2 * pi * r^2

where:

r is the radius of the cylinder

h is the height of the cylinder

In this case, the radius of the cylinder is 1 meter (half of the diameter) and the height of the cylinder is 1 meter. So the surface area of the tank is:

surface_area = 2 * pi * 1 * 1 + 2 * pi * 1^2 = 6.283185307179586

The insulation will add a thickness of 0.05 meters to the surface area of the tank, so the total surface area of the insulated tank is:

surface_area = 6.283185307179586 + 2 * pi * 1 * 0.05 = 6.806032934459293

The cost of the insulation is $40 per square meter and the cost of labor is $95 per square meter, so the total cost of the insulation and labor is:

cost = 6.806032934459293 * (40 + 95) = $1,165.73

The original cost of the tank was $10,900, so the total cost of the insulated tank is:

cost = 10900 + 1165.73 = $12,065.73

Therefore, the estimated current total cost for the installed and insulated tank is $12,065.73.

Segregation and recombination are best represented by the diagram.

In molecular biology, segregation and recombination are key processes. Segregation is the process of dividing two separate alleles present in a single organism so they can each reproduce on their own. The two alleles split and then have individual copies in the daughter cells during cellular division.

On the other hand, recombination entails joining two distinct alleles to create a new allele that is distinct from both of them. Meiosis, when genes exchange parts between chromosomes, causes this to happen. This procedure causes variation in a population, which aids in the evolution of species. Recombination and segregation are necessary for organisms to live and adapt to their environment.

A credit card trap occurs when the minimum payments required each month do not cover all the interest charges and do not reduce the principal balance. This means that even if the cardholder makes the minimum payments on time, they will still be paying only the interest charges and not reducing the amount of debt. This can result in a cycle of high-interest debt that is difficult to escape from.
