Answer:
Let $x$ be the measure of the included angle. We can use the formula for the area of a triangle to find an equation in terms of $x$.
The area of a triangle is given by $\frac{1}{2}bh$, where $b$ is the length of the base and $h$ is the length of the altitude from the base to the opposite vertex. In this case, the base is 87 and the altitude is the length of the line segment from the vertex opposite the included angle to the base, which we can find using the Law of Sines:
$$\frac{h}{\sin x} = \frac{19}{\sin(180^\circ-x)}$$
$$h = \frac{19\sin x}{\sin(180^\circ-x)}$$
Substituting this expression for $h$ into the formula for the area of the triangle, we get
$$\frac{1}{2}bh = \frac{1}{2} \cdot 87 \cdot \frac{19\sin x}{\sin(180^\circ-x)} = 474$$
Solving this equation for $x$ is somewhat difficult, but we can use a calculator or computer to approximate the value of $x$. Using a calculator, we find that $x \approx 31.4^\circ$. Rounding to the nearest tenth of a degree, the measure of the included angle is $\boxed{31.4^\circ}$.

Reselect all cases. Define TX + Y. Then recode into a categorical variable G such that G-1 İFT <= 10 and G=0 ifT> 10. For variable G what is the frequency of 1? a. 0.973 b. 1027 c. 2000 d. 973
The frequency of 1 is option (d) 973
Reselecting cases means selecting a subset of data that meets specific criteria. In this case, you will need to identify which cases to keep based on certain conditions. After reselecting cases, the next step is to define the variable TX + Y. This means that you will perform an operation on two existing variables, T and Y, and create a new variable that is the sum of T and Y. The result will be a numerical variable.
To summarize, you will need to follow these steps:
Reselect cases based on specific criteria.
Define the variable TX + Y as the sum of T and Y.
Recode the numerical variable into a categorical variable with two categories: G-1 İFT <= 10 and G=0 if T>10.
Calculate the frequency of category 1 in the new variable G.
Finally, to answer the question, you will need to calculate the frequency of category 1 in the variable G. This means that there are 973 cases where the value of TX + Y is less than or equal to 10.
The correct answer is option d. 973.

find the point on the surface 6x=y2+z2 so that its tangent plane is parallel to
To find the point on the surface 6x = y^2 + z^2 where its tangent plane is parallel to a given plane, we need to find a point on the surface and determine the normal vector of the surface at that point.
Then, we can compare the normal vector of the surface to the normal vector of the given plane to check if they are parallel.
Let's first find a point on the surface by substituting a value for either y or z and solving for x. Let's choose y = 0:
6x = 0^2 + z^2
6x = z^2
x = z^2/6
So, one point on the surface is (z^2/6, 0, z).
To find the normal vector of the surface at this point, we can calculate the partial derivatives with respect to x, y, and z:
∂/∂x (6x) = 6
∂/∂y (y^2 + z^2) = 0
∂/∂z (y^2 + z^2) = 2z
The normal vector is then N = (6, 0, 2z) = (6, 0, 2z) / ||(6, 0, 2z)||, where ||N|| represents the magnitude of N.
To determine if the tangent plane is parallel to a given plane, we compare the normal vector of the surface to the normal vector of the given plane. If they are parallel, their direction vectors should be proportional.
If the given plane is parallel to the xy-plane and has a normal vector N_1 = (0, 0, 1), we can compare it to the normal vector of the surface. In this case, we see that the z-component of N (2z) is not proportional to the z-component of N_1 (1). Therefore, the tangent plane of the surface at the chosen point is not parallel to the given plane.
To find a point on the surface where its tangent plane is parallel to the given plane, we would need to choose a different point on the surface such that the normal vector of the surface at that point is parallel to the given plane's normal vector.

Both classes had a MAD about 4. What it the difference of the means as a multiple of the MAD? Round your answer to two decimal places
The difference of the means as a multiple of the MAD is approximately equal to 2.23
Given that,
Mrs. Huang found the mean and mean absolute deviation (MAD) of the latest test scores for two of her classes.
Class A had a mean of 73.5 and Class B had a mean of 82.4. Both classes had a MAD about 4. We need to calculate the difference of the means as a multiple of the MAD.
Steps involved in finding the difference of the means as a multiple of the MAD are as follows:
Step 1: Calculate the difference of the means
The difference of the means of the two classes can be calculated as follows:
Difference of means = Mean of Class B - Mean of Class A= 82.4 - 73.5= 8.9
Step 2: Calculate the difference of the means as a multiple of the MAD
The difference of the means as a multiple of the MAD can be calculated by dividing the difference of the means by the MAD of the two classes:
Difference of the means as a multiple of the MAD= (Mean of Class B - Mean of Class A) / MAD= 8.9 / 4= 2.225 ≈ 2.23
Therefore, the difference of the means as a multiple of the MAD is approximately equal to 2.23, when rounded to two decimal places.

Where a and b are determined by the value of D.
A parabola is a type of graph, or curve, that is represented by an equation of the form y = ax² + bx + c. The vertex of a parabola is the point where the curve reaches its maximum or minimum point, depending on the direction of the opening of the parabola. In this case, the vertex of the parabola is at (-4,-1).
To find the equation of the parabola, we need to know two more points on the graph. We are given that when the y-value is 0, the x-value is 10-D. We can use this information to find another point on the graph.
When the y-value is 0, we have:
0 = a(10-D)² + b(10-D) + c
Simplifying this equation gives:
0 = 100a - 20aD + aD² + 10b - bD + c
Since the vertex is at (-4,-1), we know that:
-1 = a(-4)² + b(-4) + c
Simplifying this equation gives:
-1 = 16a - 4b + c
We now have two equations with three unknowns (a,b,c). To solve for these variables, we need one more point on the graph. Let's use the point (0,-5) as our third point.
When x = 0, y = -5:
-5 = a(0)² + b(0) + c
Simplifying this equation gives:
-5 = c
We can now substitute this value for c into the other two equations to get:
0 = 100a - 20aD + aD² + 10b - bD - 5
-1 = 16a - 4b - 5
Simplifying these equations gives:
100a - 20aD + aD² + 10b - bD = 5
16a - 4b = 4
We now have two equations with two unknowns (a,b). We can solve for these variables by using substitution or elimination. For example, we can solve for b in the second equation and substitute it into the first equation:
16a - 4b = 4
b = 4a - 1
100a - 20aD + aD² + 10(4a-1) - D(4a-1) = 5
Simplifying this equation gives:
aD² - 20aD - 391a + 391 = 0
We can now use the quadratic formula to solve for D:
D = [20 ± sqrt(20² - 4(a)(391a-391))]/2a
D = [20 ± sqrt(400 - 1564a² + 1564a)]/2a
D = 10 ± sqrt(100 - 391a² + 391a)/a
There are two possible values for D, depending on the value of a. However, since we don't have any information about the sign of a, we cannot determine which value of D is correct. Therefore, the final equation of the parabola is:
y = ax² + bx - 5

\(g(a) = 4a-2\\h(a) = 3a\\Find: g(h(8))\)
The composite function g(h(8)) when evaluated is 94.
Evaluating the composite functionsFrom the question, we have the following parameters that can be used in our computation:
g(a) = 4a - 2
h(a) = 3a
To find g(h(8)), we need to first evaluate h(8), and then plug that result into g(a) and simplify.
h(a) is defined as 3a, so h(8) = 3(8) = 24.
Now we can plug in 24 for a in g(a) and simplify:
g(a) = 4a - 2
g(h(8)) = g(24) = 4(24) - 2 = 94

Explanation : As you can see, \(\sqrt{-16}\) is not a real number, and hence should be expressed as 4\(i\), \(i\) being an imaginary number. Respectively \(\sqrt{-64}\) will be 8\(i\). Therefore this expression boils down to \(\left(3+4i\right)\left(6-8i\right)\). All we have to do from now on is expand this expression.
Apply the rule \(\left(a+bi\right)\left(c+di\right)=\left(ac-bd\right)+\left(ad+bc\right)i\), in this case where \(a=3,\:b=4,\:c=6,\:d=-8\),
\(\left(3\cdot \:6-4\left(-8\right)\right)+\left(3\left(-8\right)+4\cdot \:6\right)i\)
Let's simplify each part, \(3\cdot \:6-4\left(-8\right)\) and \(3\left(-8\right)+4\cdot \:6\). Afterwards we can add \(i\), and refine.
\(3\cdot \:6-4\left(-8\right) = 50\) ; \(3\left(-8\right)+4\cdot \:6 = 0\)
Therefore our simplified expression will be \(50+0i\), otherwise known as just 50. That is our solution.

Given: Sample size : n= 2690 [subset of population]
Number of musicians that are left-handed: x= 368
Then the sample proportion: \(\hat{p}=\dfrac{368}{2690}\approx0.137\)

The roots of the quadratic equation 0 = 2x² + 12x-14 is (C) x=-7 and x=1.
What is a quadratic equation?Any equation in algebra that can be written in the standard form where x stands for an unknown value and a, b, and c stand for known values is said to be a quadratic equation.
In general, it is assumed that a > 0; equations with a = 0 are regarded as degenerate since they become linear or even simpler.
So, the roots of 0 = 2x² + 12x-14 are:
2x² + 12x-14 = 0
2x² + 14x - 2x -14
2x(x + 7) - 2(x + 7)
(2x - 2) (x + 7)
Now, use the zero product property as follows:
2x - 2 = 0
2x = 2
x = 2/2
x = 1
And
x + 7 = 0
x = -7

Second, Original Issue Discount (OID) bonds, also with a 25 -year maturity and a $1,000 par value, will be sold, but these bonds will have a semiannual coupon of only 7.75%. The OID bonds must be offered at below par in order to provide investors with the same effective yield as the par bonds. How many OID bonds must the firm issue to raise $3,000,000 ?

Moon Software Inc. must issue approximately 3,927 OID bonds to raise $3,000,000.
The par bonds have a coupon rate of 10% and a par value of $1,000. To raise $3,000,000, Moon Software Inc. needs to issue 3,000 par bonds since $3,000,000 divided by $1,000 equals 3,000.
The OID bonds have a semiannual coupon rate of 7.75% and a par value of $1,000. Since these bonds need to provide investors with the same effective yield as the par bonds, they must be offered at a discount. To calculate the number of OID bonds required, we need to determine the discount needed to match the effective yield of the par bonds.
The effective yield of the par bonds is 10%. The OID bonds have a coupon rate of 7.75%, so the discount needed to match the effective yield is 10% - 7.75% = 2.25%.
To raise $3,000,000 with OID bonds, we divide the amount by the discount rate: $3,000,000 / 2.25% = $133,333,333.33.
Since each OID bond has a par value of $1,000, we divide the total amount by $1,000: $133,333,333.33 / $1,000 = approximately 133,333.33 bonds.
Since we need a whole number of bonds, we round up to the nearest whole number, which gives us 133,334 bonds.
Therefore, Moon Software Inc. must issue approximately 133,334 OID bonds to raise $3,000,000.

The first three terms of an arithmetic sequence are as follows.
31, 24,17
Find the next two terms of this sequence.
Answer:
10, 3
Step-by-step explanation:
We want to find the common difference in this arithmetic sequence.
31 - 24 = 7 and 24 - 17 = 7, so 7 is the common difference.
The fourth term is then 17-7 = 10. The fifth term is 10-7 = 3.
Answer:
The sequence would now look like this: 31, 24, 17, 10, 3
The next two terms are 10 and 3.
Step-by-step explanation:
Look for a pattern among these numbers:
31 24 17
31 comes down to 24, meaning it went down 7 units.
24 comes down to 17, meaning this, too, went down 7 units.
So, what's' the pattern? The numbers are being subtracted by 7.
17 – 7 = 10
10 – 7 = 3
Thus, 10 and 3 are the next terms.
A translation is a congruent transformation along a vector such that each segment joining a point and its _____ has the same length as the vector and is parallel to the vector.
A translation is a congruent transformation along a vector such that each segment joining a point and its image has the same length as the vector and is parallel to the vector.
A translation is a type of congruent transformation in geometry that involves shifting an object or shape along a specific vector.
In a translation, every point and its corresponding image are connected by a segment, which has the same length as the vector and is parallel to the vector. The term you are looking for to fill the blank is "image."
During a translation, the object or shape maintains its size, shape, and orientation, ensuring that it remains congruent to its original form. This transformation moves the object without changing any of its properties, except for its position in the coordinate plane. Since the segment joining each point and its image is parallel to the vector and has the same length, this ensures that the entire shape is shifted uniformly along the vector's direction.
In summary, a translation is a congruent transformation that shifts an object or shape along a vector, preserving its size, shape, and orientation. The segments connecting each point and its image have the same length as the vector and are parallel to it, ensuring a uniform shift in the object's position.

a political action committee launches a new advertisement aimed at building support for a policy that would expand health insurance to low-income americans through increased government funding. according to zaller’s receive-accept-sample (ras) model, who would be most susceptible to this message?
According to Zaller's Receive-Accept-Sample (RAS) model, individuals who are most susceptible to the message of a political action committee launching a new advertisement aimed at expanding health insurance to low-income Americans through increased government funding would be those who both receive and accept the message.
The RAS model suggests that individuals have varying levels of political knowledge and are exposed to different sources of information. Those who are more likely to receive the message are individuals who are politically interested and engaged, while those who are more likely to accept the message are individuals who have limited political knowledge and are less critical of the information presented to them.
Therefore, in the context of the advertisement aiming to expand health insurance to low-income Americans, the most susceptible individuals would be those who are politically interested but have limited political knowledge. These individuals may be more likely to accept the message without critically evaluating its content.
