We need to simplify the given expression . The given expression is ,
→ 1/ ( m - n) - (m + n)/ ( m² - n² )
→ 1/ ( m - n) - ( m + n)/(m+n)(m-n)
Using a² - b² = (a+b)(a-b) Now cancel m+n in numerator and denominator .→ 1/( m - n) - 1/ ( m - n)
→ 0
Hence the required answer is 0 .A quadrilateral ABCDEFG, Vertical line ABCD, horizontal line from D to the left DEF, EG slanting line to the left, G connects with the vertical line B. A line connects G and C and a line connects B and F, and the line connects C and E.
In the diagram shown above, quadrilateral CEFH is a parallelogram.
Using properties of angles, triangles, and quadrilaterals, order the angles listed on the tiles from least measure to greatest measure.
The order of the angles from the least measure to greatest measure is ∠HGB, ∠ECD, ∠FGH and ∠GBH. The solution has been obtained by using the properties of angles.
What is an angle?
When two rays or lines share an endpoint, they form an angle, which is a figure in plane geometry.
We are given that CEFH is a parallelogram. We know that the adjacent angles of a parallelogram are supplementary.
So,
⇒∠FEC + ∠HCE = 180°
⇒124° + ∠HCE = 180°
⇒∠HCE = 56°
We know that angles on a straight line form a linear pair.
So,
⇒∠BCH + ∠HCE + ∠ECD = 180°
⇒90° + 56° + ∠ECD = 180°
⇒∠ECD = 34°
We know that the opposite angles of a parallelogram are equal.
So,
⇒∠FEC = ∠FHC
⇒∠FHC = 124°
Now,
⇒∠FHC + ∠FHG = 180°
⇒∠FHG = 56°
Using the angle sum property of triangle, we get
⇒∠FHG + ∠FGH + ∠GFH = 180°
⇒56° + ∠FGH + 87° = 180°
⇒∠FGH = 37°
∠GHB = 124° (Vertically opposite angles)
∠CHB = 56° (Vertically opposite angles)
Using the angle sum property of triangle, we get
⇒∠BCH + ∠CHB + ∠HBC = 180°
⇒90° + 56° + ∠HBC = 180°
⇒∠HBC = 34°
∠GBH = 44° (Straight line angle)
∠HGB = 12° (Angle sum property of triangle)
Hence, order of the angles from the least measure to greatest measure is ∠HGB, ∠ECD, ∠FGH and ∠GBH.

b. $844,329.90
c. $649,688.15
d. $786,727.08
e. $748,056.60
To calculate the terminal value of the firm at time 3, we can use the Gordon Growth Model formula:
Terminal Value = Cash Flow at Time 3 * (1 + Growth Rate) / (Discount Rate - Growth Rate)
Given: Cash Flow at Time 3 = $73,900 Growth Rate = 2.2% Discount Rate = Risk-Free Rate + Beta * Market Risk Premium Risk-Free Rate
= 3.6% Beta
= 1.47 Market Risk Premium
= 7.4%
First, let's calculate the Discount Rate: Discount Rate = 3.6% + 1.47 * 7.4% = 3.6% + 10.8378%
= 14.4378%
Now, we can calculate the Terminal Value: Terminal Value = $73,900 * (1 + 2.2%) / (14.4378% - 2.2%) ≈ $73,900 * 1.022 / 0.1213778 ≈ $73,900 * 8.4258
Terminal Value ≈ $623,444.42
Therefore, the correct option for the terminal value of the firm at time 3 is: a. $667,229.73 (None of the provided options matches the calculated value)

Parametric models are reliable when the models are flexible in terms of the project's size. Group of answer choices True False
It is false that Parametric models are reliable when the models are flexible in terms of the project's size
Parametric models are mathematical models that make assumptions about the distribution of the data being modeled. These models rely on the estimation of one or more parameters that define the distribution, such as the mean and variance of a normal distribution.
While parametric models can be very useful when the underlying assumptions are met and the data follows the assumed distribution, they can be unreliable when the assumptions are not met. For example, if the data does not follow a normal distribution, using a parametric model based on a normal distribution may lead to incorrect conclusions.
In terms of project size, the reliability of parametric models depends on the specific model and the nature of the data being modeled. Some parametric models may be more or less flexible in terms of accommodating different sample sizes or project sizes. However, in general, the reliability of a parametric model depends on the appropriateness of the underlying assumptions and the fit of the model to the data, rather than the size of the project.

Fogo de Chao is offering a 14% discount for purchasing 3 entrees. Each entree cost $35.
What is the total price of 3 entrees including 6% sales tax?
Answer:
The total price to pay is $95.718.
Step-by-step explanation:
Solve for the total cost of the entrees first
$35(3) = $105
Taking off 14%, that means that the customer is only to pay
100% - 14% = 86% of the total price or 0.86 in decimal
Discounted price = $105(0.86)
Discounted price = $90.30
Lastly, add the 6% sales tax or 0.06 in decimal
Total price = $90.30(1.06)
Total price = $95.718

Write an equivalent equation using the Subtraction Property of Equality
9y = 4y + 10
(explain how to do this to)
The Equivalent equation using the Subtraction Property of Equality is y = 2.
what is Subtraction Property of Equality?According to the Subtraction Property of Equality, if two equal items have an equal value subtracted from them or deleted, the result is a new equal amount. When two equivalent sides of a mathematical statement are separated by an equal sign, an equation is being expressed. The subtraction property is expressed as follows: If a = b, then a - c = b - c.In order to balance an equation, one must apply the same mathematical operation on both sides, which is known as the subtraction property of equality.If we have an expression as ( a + b ) = c
Then as per subtraction property of equality [ (a + b ) - b = c - b ]
Here given 9y = 4y + 10
Simplifying this equation, we get
⇒9y - 4y = 10
⇒( 9 - 4 )y = 10
⇒5y = 10
therefore, y = ( 10 ÷ 5 )
⇒y = 2
Therefore the equivalent equation is y = 2.

A company uses samples of size 9 to construct an X-bar chart to control the mean of the diameter of a drive shaft. On a certain day, a new employee takes a sample of size 4 and plot this sample average on the X-bar chart that is constructed with samples of size 9. Assuming the process is in control, what is the probability that this sample average falls outside the 3- sigma control limits of the X-bar chart?
Group of answer choices
0.00%
0.27%
1.24%
4.55%
13.36%
18.35%
31.73%
The probability that the sample average falls outside the 3-sigma control limits of the X-bar chart is 0.27%.
The 3-sigma control limits are calculated using the standard deviation of the process. If the process is in control, then 99.73% of the sample averages will fall within the 3-sigma control limits. The remaining 0.27% of the sample averages will fall outside the control limits.
In this case, the sample size is 4, which is smaller than the sample size of 9 that was used to construct the control chart. This means that the control limits for the sample of size 4 will be narrower than the control limits for the sample of size 9.
As a result, the probability that the sample average falls outside the control limits will be higher for the sample of size 4.
Specifically, the probability that the sample average falls outside the 3-sigma control limits for a sample of size 4 is 0.27%. This means that there is a 0.27% chance that the new employee will observe a sample average that falls outside the control limits, even if the process is in control.

Answer: 6x^2 - 17x + 12.
Step-by-step explanation:
To multiply these two binomials, we can use the FOIL method, which stands for First, Outer, Inner, Last. This gives us:
(2x - 3)(3x - 4) = (2x)(3x) + (2x)(-4) + (-3)(3x) + (-3)(-4)
Simplifying each term, we get:
(6x^2) + (-8x) + (-9x) + 12
Combining like terms, we can simplify this to:
6x^2 - 17x + 12
Therefore, (2x-3)(3x-4) can be expressed as the trinomial 6x^2 - 17x + 12.

A researcher is attempting to reduce error and avoid a type i error so nurses can have confidence in inferring findings to another practice setting. what occurs in a type i error?
A type I error occurs when a researcher mistakenly rejects a true null hypothesis. In other words, it is a false positive result. Let's break down what happens in a type I error:
1. The researcher starts with a null hypothesis, which assumes that there is no significant relationship or effect between the variables being studied.
2. To test the null hypothesis, the researcher collects data and performs statistical analysis.
3. In a type I error, the researcher incorrectly concludes that there is a significant relationship or effect when, in fact, there is none.
4. This error can happen due to various reasons, such as sample size, random chance, or flaws in the experimental design.
To avoid type I errors, researchers typically set a predetermined significance level (often denoted as α) before conducting the study. The significance level represents the probability of making a type I error. By setting a lower significance level, such as α = 0.05, researchers aim to reduce the chances of mistakenly rejecting the null hypothesis.
In the context of the given question, if the researcher is trying to reduce error and avoid a type I error, it means they want to minimize the risk of incorrectly inferring findings to another practice setting. This would increase the confidence that nurses have in applying the research findings to their own work.

An implicit equation for the plane passing through the points (-4,-1,5). (-9, 0, 10), and (1, -4,5) is____
To find an implicit equation for the plane passing through the points (-4, -1, 5), (-9, 0, 10), and (1, -4, 5), we can use the cross product of two vectors in the plane.
Let's denote the three points as A (-4, -1, 5), B (-9, 0, 10), and C (1, -4, 5).
First, we find two vectors in the plane by taking the differences between the points:
Vector AB = B - A = (-9, 0, 10) - (-4, -1, 5) = (-5, 1, 5)
Vector AC = C - A = (1, -4, 5) - (-4, -1, 5) = (5, -3, 0)
Next, we calculate the cross product of these two vectors:
Normal vector N = AB x AC
= (-5, 1, 5) x (5, -3, 0)
Using the determinant expansion method to calculate the cross product, we get:
N = (1 * 0 - 5 * (-3), 5 * 0 - (-5) * 0, -5 * (-3) - 1 * 5)
= (15, 0, 10)
Now, we have the normal vector of the plane as N = (15, 0, 10).
Using the general equation for a plane, Ax + By + Cz + D = 0, where (A, B, C) is the normal vector, we can substitute the values:
15x + 0y + 10z + D = 0
To find D, we substitute one of the points in the equation. Let's use point A (-4, -1, 5):
15 * (-4) + 0 * (-1) + 10 * 5 + D = 0
-60 + 0 + 50 + D = 0
-10 + D = 0
D = 10
Therefore, the implicit equation for the plane passing through the points (-4, -1, 5), (-9, 0, 10), and (1, -4, 5) is:
15x + 10z + 10 = 0.

All linear ODEs have the property that linear combinations of their solutions are also solutions of the ODE. True or false
That is, if \(y_1(x), y_2(x), ..., y_n(x)\)are all solutions of the ODE, then any linear combination of the form \(c_1y_1(x) + c_2y_2(x) + ... + c_n*y_n(x)\) is also a solution of the ODE, where \(c_1, c_2, ..., c_n\) are constants.
True.
This property is known as the superposition principle for linear ODEs, and it arises from the linearity of the differential equation. A linear ODE is an ODE of the form:
\(a_n(x)y^(n) + a_(n-1)(x)y^(n-1) + ... + a_1(x)y' + a_0(x)y = f(x)\)
where y^(k) denotes the k-th derivative of y(x) with respect to x, and \(a_n(x), a_(n-1)(x), ..., a_1(x), a_0(x)\)and f(x) are given functions of x.
Suppose that y1(x) and y2(x) are both solutions of this ODE, so that when we substitute them into the differential equation, we get:
\(a_n(x)y1^(n) + a_(n-1)(x)y1^(n-1) + ... + a_1(x)y1' + a_0(x)y1 = f(x)\)
and
\(a_n(x)y2^(n) + a_(n-1)(x)y2^(n-1) + ... + a_1(x)y2' + a_0(x)y2 = f(x)\)
We want to show that any linear combination of y1(x) and y2(x), such as c1y1(x) + c2y2(x) where c1 and c2 are constants, is also a solution of the ODE.
To do this, we substitute the linear combination into the differential equation:
\(a_n(x)(c1y1(x) + c2y2(x))^(n) + a_(n-1)(x)(c1y1(x) + c2y2(x))^(n-1) + ... + a_1(x)(c1y1'(x) + c2y2'(x)) + a_0(x)(c1y1(x) + c2y2(x)) = f(x)\)
Using the linearity of differentiation and the distributive property of multiplication, we can simplify this expression:
\(c1(a_n(x)y1^(n) + a_(n-1)(x)y1^(n-1) + ... + a_1(x)y1' + a_0(x)y1) + c2(a_n(x)y2^(n) + a_(n-1)(x)y2^(n-1) + ... + a_1(x)y2' + a_0(x)y2) = f(x)\)
Since y1(x) and y2(x) satisfy the differential equation individually, the expressions in parentheses on the left-hand side are equal to f(x). Therefore, we have shown that the linear combination c1y1(x) + c2y2(x) also satisfies the differential equation, and is therefore a solution of the ODE.
In general, this result extends to any finite linear combination of solutions of the ODE. That is, if y1(x), y2(x), ..., yn(x) are all solutions of the ODE, then any linear combination of the form c1y1(x) + c2y2(x) + ... + cn*yn(x) is also a solution of the ODE, where c1, c2, ..., cn are constants.
