By evaluating the function we will see that the difference is:

f(1) - f(-7)  = 3

Here we have a piecewise function, this is a function that behaves differently on different intervals of its domain.

On the image you can see the different pieces of the function, and on the right the domain of each of the pieces.

The first part works for all the values smaller than -4 and x = -4.

So if we want to evaluate the function in x = -7, we need to use that piece:

f(-7) = |-7 + 5| - 9 = -7

And the second piece works on the interval (-4, 1], so to evaluate in x = 1 we need to use that piece.

f(1) = -1³ - 3*1 = -4

Then the difference is:

f(1) - f(-7) = -4 + 7 = 3

The shortest length of fence that the rancher can use is 6000 ft.

What is meant by length?

The measuring of one thing from finish to finish or on its longest aspect, or a measuring of a selected a part of one thing is known as length.

Main Body:

x = width of rectangle

y = length of rectangle

A = area of rectangle = xy = 1500000 ft^2

L = length of fencing needed = 2(x + y) + x = 3x + 2y

L = 3x + 2(1500000/x) = 3x + 3(10^6)x^(-1)

As x –> 0+, L –> +inf.

As x –> +inf, L –> (3x)+.

Sketch and see that there will be a minimum in Quadrant I.

dL/dx = 3 - 3(10^6)x^(-2)

Extrema occur when dL/dx = 0:

3 - 3(10^6)x^(-2) = 0

(10^6)x^(-2) = 1

x^2 = 10^6

x > 0, so x = 1000 feet for shortest length.

Hence,Shortest L = 3000 + 3(10^6)(10^3)^(-1) = 6000 feet.

Answer:

[tex]a_{n}[/tex] = 18 - 3n

Step-by-step explanation:

there is a common difference between consecutive terms in the sequence, that is

12 - 15 = 9 - 12 = 6 - 9 = - 3

this indicates the sequence is arithmetic with nth term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

here a₁ = 15 and d = - 3 , then

[tex]a_{n}[/tex] = 15 - 3(n - 1) = 15 - 3n + 3 = 18 - 3n

Using the numbers to indicate their locations as pairs of x and y values. Euclidean distance is used to measure all distances.

a. Using the k-means algorithm, we can group the points into three clusters based on their initial cluster centers. The first cluster consists of the points (18, 10), (21, 11), (22, 22), (24, 15), (26, 12), and (26, 13), the second cluster consists of the points (27, 14), (40, 27), (41, 29), (42, 20), and (44, 28), and the third cluster consists of the points (30, 33), (31, 39), (35, 37), (39, 44), (46, 21), (47, 30), (48, 31), and (49, 23).

The silhouette approach, which compares how similar each point is to the points in its own cluster to the points in other clusters, can be used to assess the quality of the clusters. A high silhouette value denotes a well-clustered point, while a low silhouette value denotes a possible incorrect cluster assignment.

b. In hierarchical agglomerative clustering, we first create individual clusters for each point, which are then combined to create a single cluster that contains all of the points. Depending on how they calculate the separation between clusters, the three distinct link approaches will result in a variety of clustering outcomes.

The minimal distance between any two points in each of the two clusters is used by single link to calculate the separation between the clusters. Because it only takes into account the closest pair of points, this can lead to long, thin clusters.

The distance between the clusters is calculated using the maximum distance between any two points in the two clusters. Due to the fact that it only takes into account the farthest pair of points, this can lead to compact, spherical clusters.

The average link calculates the separation between the two clusters by averaging out all of the distances between the points in the two clusters. This takes into account all possible pairs of points and may lead to clusters with more symmetrical shapes.

In general, a single link will create clusters that are the most compact, a complete link will create clusters that are the most spherical, and an average link will create clusters that are more evenly shaped.

Maximum area to enclose a rectangular pasture with one side up against a river is equal to 500,000 square feet.

As given in the question,

Let 'l' be the length of the rectangular pasture

And 'w' be the width of the rectangular pasture

Condition:

One side of the pasture is up against a river

Perimeter of the rectangular pasture with one side up against river = l + 2w

⇒ 2000 = l + 2w

⇒ l = 2000 - 2w

Area of the rectangular pasture

=( 2000 - 2w )( w )

= - 2 ( w² - 1000w )

= -2( w² - 1000w + 250000 - 250000 )

= -2 ( w - 500 )² + 500, 000

Maximum area is at w = 500

Maximum area is 500,000

Therefore, the maximum area of the given rectangular pasture is 500,000 square pasture.

Since the sun must rise tomorrow, then the probability of the sun rising tomorrow is much larger than one.

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty. The higher the probability of an event, the more likely it is that the event will occur. A simple example is the tossing of a fair (unbiased) coin. Since the coin is fair, the two outcomes ("heads" and "tails") are both equally probable; the probability of "heads" equals the probability of "tails"; and since no other outcomes are possible, the probability of either "heads" or "tails" is 1/2 (which could also be written as 0.5 or 50%).

These concepts have been given an axiomatic mathematical formalization in probability theory, which is used widely in areas of study such as statistics, mathematics, science, finance, gambling, artificial intelligence, machine learning, computer science, game theory, and philosophy to, for example, draw inferences about the expected frequency of events. Probability theory is also used to describe the underlying mechanics and regularities of complex systems.

Firstly, it is important to clarify that when people say ‘‘The Sun Will Rise Tomorrow’ they are implying only how It only appears to an observer on earth that the sun rises and sets. In reality the sun neither rises nor sets it only appears to do so because the earth takes one day (24 hours to rotate on its axis). It has appeared to do this for as long as the earth has existed (approx. 4.5 billion years). Although for the purpose of this short reflection, the idiom will signify part of the day-night process -being able to see the sun rise from the perspective of a human on earth.

Although the chances might be extremely high, they are not certain. Even thought it may be very improbably unless an infinite amount of days in which the sun has risen has occurred, the probability will not exactly be one. Ludwig Wittgenstein, Austrian-British philosopher who worked primarily in logic and philosophy of mathematics, said, “It is an hypothesis that the sun will rise tomorrow: and this means that we do not know whether it will rise.” Although we may reasonably argue that the earth while rise tomorrow to a 99.99999999% chance, there still is that 0.000000001 which states that it would not in fact rise.

Let A represent the new pesticide and B be the Ant Killer. Then, you are given that

Brand1 kills ants in 65 of 100 containers:

Xa = 65/100 = 0.65

Brand2 kills ants in 58 of 100 containers:

Xb = 58/100 = 0.58

You know need to find sample variance for both,

s²A =∑(Xi - Xa)²

= 65(1-0.65)² + 35(0 - 0.65)²

= 22.75

s²B =∑(Xi - Xb)²

= 59(1-0.59)² + 41(0 - 0.59)²

= 24.19

You can know do a test for significance

t = (Xa - Xb) / √(sA /nA) +(sB/nB)

and derive the conclusion from there.

Here, Null and alternative hypothesis are generally,

Alternative hypothesis

Here, there are three samples are assumed. They are:

i) Samples are taken independently

ii) Samples must be selected randomly

iii) n₁p₁ ≥ 5 , n₁q₁ ≥ 5, n₂p₂ ≥ 5, n₂q₂ ≥ 5

i.e., p₁ = 0.65 ; p₂ = 0.58 , n₁ = 100

q₁ = 0.35 ; q₂ = 0.42 , n₂=100

Corresponding p-value at Z = 1.01722

The number of quarters and dimes in the jar is 20 and 30 respectively.

Let

d + q = 50

0.10d + 0.25q = 8

From (1)

d = 50 - q

Substitute into equation (2)

0.10d + 0.25q = 8

0.10(50 - q) + 0.25q = 8

5 - 0.10q + 0.25q = 8

q = 3/0.15

q = 20

Substitute q = 20 into (1)
