a senate committee consists of 5 republicans, 6 democrats, and 2 independents. a subcommittee of 3 members is randomly chosen. what is the probability that the subcommittee (a) consists of 3 republicans?
Considering all the given information, the probability that the subcommittee consists of 3 republicans is 0.0345, or 3.45%.
To find the probability that the subcommittee consists of 3 Republican’s, we first calculate the number of ways to choose 3 Republicans out of 5:
C(5, 3) = 5! / (3! (5 - 3)!)
=5! / (3! 2!)
= (5 ×4 × 3!) / (3 × 2 × 3!)
= (5 × 4) / (2 × 2)
= 10.
The total number of ways to choose 3 members out of a committee of 5 Republicans, 6 Democrats, and 2 Independents is:
C(13, 3) = 13! / (3! (13 - 3)!)
=13! / (3! 10!)
= (13 × 12 × 11 × 10!) / (3 × 2 × 1 × 10!)
= (13 × 12 × 11) / (3 × 2 × 1)
= 286
So the probability of choosing 3 Republicans is:
P(3 Republicans) = 10 / 286 = 1/29
Therefore the probability of the subcommittee consisting of 3 Republicans is approximately 0.0345, or 3.45%.

In 1852, an Indian mathematician, Radhanath Sikdar, used measurements and trigonometry to calculate the height of Peak XV in the Himalayas (later to be named Mount Everest). This required the use of a device that measured angles from the ground to the top of an object. By measuring the angle to the top of Peak XV from two different spots, and knowing the distance between these spots, Sikdar may have come up with a drawing like the following: The angle of elevation to the top of the peak (from point B) was measured to be 32 degrees. From a point 17409.7 feet closer (point A), the angle of elevation was 45 degrees. Find the height Sikdar calculated for Peak XV.
The height Sikdar calculated for Peak XV is approximately 29105.77 feet.
How to calculate the heightLet's first find the height of point A above the ground. We can use the tangent function:
tan(45) = height of A / d
height of A = d * tan(45)
height of A = 17409.7 * tan(45) = 17409.7 feet
h / (d - 17409.7) = height of A / d
h = (height of A * (d - 17409.7)) / d
h = (17409.7 * (17409.7 / tan(32) - 17409.7)) / (17409.7 / tan(32))
= 29105.77 feet

LM is the midsegment of trapezoid ABCD. If AB = 34 and DC = 128 , what is LM
Answer:81
Step-by-step explanation: AB=base 1 DC=base 2
Base1+Base2 divided by 2
The length of the midsegment of the trapezoid is 81 units.
How to find the mid segment of a trapezoid?The midsegment of a trapezoid is the line segment connecting the midpoints of the two non-parallel sides of a trapezoid.
The length of the midsegment of a trapezium is half the sum of the top and bottom of the trapezoid.
Therefore, let's find LM, the midsegment of the trapezoid.

What is triangle?Triangulus, which means "three-cornered" or "having three angles," is a Latin word with roots in tri-, "three," and angulus, "angle or corner." Three vertices make up a triangle, a three-sided polygon. The triangle's angles are formed at a point where the three sides are joined end to end. The summation of the triangle's three angles equals 180 degrees. Triangles can be classified as equilateral, isosceles, or scalene depending on how long their sides are.
Consider, the triangle ABC and the mid-segment line becomes CD.

what is meant by the term "discrete" when it is used in the context of this course, as in "discrete structures", or "discrete mathematics"?
In mathematics, the term "discrete" is often used to refer to objects or structures that are distinct and separate, rather than being continuous or flowing. In the context of this course, the term "discrete" is used to describe a particular branch of mathematics known as "discrete mathematics" or "discrete structures."
Discrete mathematics is concerned with mathematical structures that are countable and finite, rather than continuous or infinite. These structures are typically represented by sets, graphs, or other discrete objects, and can be used to model a wide range of phenomena, from computer algorithms to social networks.
One of the key features of discrete structures is that they are composed of individual, separate elements, rather than being continuous or flowing. For example, a set of integers is a discrete structure, because it consists of separate, distinct integers, rather than a continuous range of numbers. Similarly, a graph is a discrete structure, because it consists of separate vertices and edges, rather than a continuous line.
Because of their discrete nature, these structures can be analyzed and manipulated using a range of mathematical tools and techniques, such as combinatorics, graph theory, and probability theory. This makes discrete mathematics a fundamental part of many areas of computer science, engineering, and other fields that rely on mathematical modeling and analysis.
In contrast, continuous structures, such as real numbers or geometric shapes, are often analyzed using calculus or other techniques that deal with the infinite and continuous nature of these objects.
In summary, when we talk about "discrete structures" or "discrete mathematics," we are referring to mathematical objects and structures that are countable, finite, and composed of individual, separate elements. These structures can be analyzed and manipulated using a range of mathematical tools, and are a fundamental part of many areas of computer science, engineering, and other fields that rely on mathematical modeling and analysis.

A 100-horsepower outboard motor at full throttle will rotate its propeller at exactly 4700 revolutions per min. Find the angular speed of the propeller in radians per second.
4700 rev per min _____ radians per sec
(Round to the nearest tenth as needed.)
Rounding to the nearest tenth, the angular speed of the propeller is 157.1 rad/s.
What do you mean by radian?A radian is a unit of measurement for angles in mathematics. It is defined as the ratio of the length of an arc of a circle to the radius of the circle. In other words, one radian is equal to the angle created at the center of a circle by an arc that is equal in length to the radius of the circle.
Radians are used as a more natural and convenient way to measure angles than degrees, especially in calculus and other branches of mathematics that deal with the study of curves and functions. For example, the trigonometric functions (sine, cosine, and tangent) are defined in terms of radians, and the derivatives of these functions are easier to work with in radians than in degrees
To convert from revolutions per minute to radians per second, we need to divide by the number of minutes in one hour and multiply by the number of radians in one revolution. We can write this conversion as:
4700 rev/min * (2π rad/rev) / (60 min/hr) = w rad/s
where w denotes the angle's rotational speed in radians per second. Plugging in the conversion factor for one revolution, we get:
w = 4700 rev/min * (2π rad/rev) / (60 min/hr) = (4700 * 2π) / 60 = 157.07 rad/s

Express sin(a)+sin(2a)+sin(3a) as a product
The expression as product is sin(a)(4 + 2cos(a) - 4sin²(a))
How to express as productFrom the question, we have the following parameters that can be used in our computation:
sin(a)+sin(2a)+sin(3a)
By sine rule, we have
sin(a)+sin(2a)+sin(3a) = sin(a) + 2sin(a)cos(a) + sin(3a)
Factor out sin(a)
sin(a)+sin(2a)+sin(3a) = sin(a)(1 + 2cos(a)) + sin(3a)
Expanding sin(3a), we have
sin(a) + sin(2a) + sin(3a) = sin(a)(1 + 2cos(a)) + 3sin(a) - 4sin³(a)
So, we have
sin(a) + sin(2a) + sin(3a) = sin(a)(1 + 2cos(a) + 3 - 4sin²(a))
Evaluate the like terms
sin(a) + sin(2a) + sin(3a) = sin(a)(4 + 2cos(a) - 4sin²(a))
Hence, the product expression is sin(a)(4 + 2cos(a) - 4sin²(a))

are we guaranteed that a solution exists? what is the guaranteed minimum radius of convergence for a taylor series expansion about the origin? is the solution unique?
The existence, uniqueness, and minimum radius of convergence of a Taylor series expansion about a point depend on the function being expanded. In general, there is no guarantee that a Taylor series will exist or be unique for every function.
Taylor Series ExpansionA Taylor series expansion of a function about a point is a representation of the function as an infinite sum of terms involving powers of the difference between the independent variable and the point. If the function is well-behaved near the point, its Taylor series will converge to the function within some interval around the point. The smallest such interval is called the radius of convergence.
If the function is infinitely differentiable (i.e. has derivatives of all orders) near the point, its Taylor series will converge to the function within the entire interval of convergence. In this case, the solution is said to be unique. However, if the function is not infinitely differentiable, it may not be possible to find a Taylor series that converges to the function, or there may be multiple Taylor series that converge to the function within different intervals.
The minimum radius of convergence of a Taylor series is difficult to determine in general, as it depends on the behavior of the function at infinity. In some cases, the radius of convergence can be estimated using techniques such as Cauchy-Hadamard theorem. However, in general, determining the exact radius of convergence requires knowledge of the behavior of the function at all points, not just near the point of expansion.

Find the slope of the ocean floor connecting the edge of the continental shelf and the beginning of the oceanic crust. That section of the ocean floor is called the continental slope.
The slope of the ocean floor is: slope = (y2 - y1) / x
What is slope?
The slope or gradient of a line in mathematics is a quantity that specifies both the direction and the steepness of the line.
The slope of the ocean floor can be found by using the formula for the slope of a line:
slope = (change in y) / (change in x)
where the change in y is the difference in depth between the edge of the continental shelf and the beginning of the oceanic crust, and the change in x is the distance along the ocean floor between these two points.
Let's call the depth of the water at the edge of the continental shelf "y1" and the depth of the water at the beginning of the oceanic crust "y2". Then, the change in y is:
change in y = y2 - y1
Similarly, let's call the distance along the ocean floor between these two points "x". Then, the change in x is:

All 6 members of a family work. Their hourly wages (in dollars) are the following.
20, 30, 13, 10, 22, 37
Assuming that these wages constitute an entire population, find the standard deviation of the population. Round your answer to two decimal places
Answer:
Step-by-step explanation:
σ = sqrt [ Σ ( xi - μ )^2 / N ]
where:
σ is the standard deviation
Σ is the sum of the values
xi is the value of the i-th observation
μ is the mean of the population
N is the number of observations
First, we need to find the mean of the population:
μ = (20 + 30 + 13 + 10 + 22 + 37) / 6
μ = 132 / 6
μ = 22
Next, we can calculate the deviations of each observation from the mean:
20 - 22 = -2
30 - 22 = 8
13 - 22 = -9
10 - 22 = -12
22 - 22 = 0
37 - 22 = 15
Then, we square each deviation:
(-2)^2 = 4
8^2 = 64
(-9)^2 = 81
(-12)^2 = 144
0^2 = 0
15^2 = 225
We add up the squared deviations:
4 + 64 + 81 + 144 + 0 + 225 = 518
We divide by the number of observations and take the square root:
σ = sqrt [ Σ ( xi - μ )^2 / N ]
σ = sqrt (518 / 6)
σ ≈ 10.72
Therefore, the standard deviation of the population is approximately 10.72 dollars.

the shaded area is the "true" region or area, and the non-shaded is the "false" region, hmmm let's work our way from the "false" region.
first off, the line is solid, that means the line includes values in the inequality, meaning the shaded part extends to the borderline, so the inequality will be either ⩾ or ⩽, let's work it out from the "false" region, by picking out a point there, hmmm let's use say x = 6 and y = -4, so the point is (6 , -4) and let's plug it in the EQUATion.
[tex]y ~~ \square ~~ \cfrac{3}{4}x-3\hspace{5em}(6~~,~-4)\qquad \implies \qquad -4 ~~ \square ~~ \cfrac{3}{4}(6)-3 \\\\\\ -4 ~~ \square ~~ \cfrac{18}{4}-3\implies -4 ~~ \square ~~ \cfrac{9}{2}-3\implies -4 ~~ \square ~~ \cfrac{9-6}{2}\implies -4 ~~ \square ~~ \cfrac{3}{2} \\\\\\ -4 ~~ \square ~~ 1.5\qquad \textit{is -4 greater or less than 1.5?}[/tex]
well, clearly -4 is less than 1.5, however to make that a false statement, we can say that -4 is more than 15, now, is not true, is "false" and since we're working from the "false" region, that is what we need, "more than", or ⩾
[tex]{\Large \begin{array}{llll} y\geqslant \cfrac{3}{4}x-3 \end{array}}[/tex]
now, bear in mind that we could have started from the "true" region, the shaded one, and pick a point in it like (0 , 0), if you test, that gives us something like 0 [ ] -3, to make that true, we make it 0 ⩾ -3, because that is true, 0 is really greater than -3, and working for the "true" region, that's what we need.

The vertex form of a parabola is:
y = a (x − h)² + k
Given that the leading coefficient is 1 and the vertex is (2,5):
y = (x − 2)² + 5
Distributing:
y = x² − 4x + 4 + 5
y = x² − 4x + 9
Alternatively, using calculus, if y = x² + px + q, then the derivative is:
dy/dx = 2x + p
The turning point occurs when the derivative is 0:
0 = 2x + p
0 = 2(2) + p
p = -4
Plugging in and solving for q:
y = x² − 4x + q
5 = (2)² − 4(2) + q
5 = 4 − 8 + q
q = 9
