The race horse's speed is approximately 256 furlongs per fortnight.

To determine the race horse's speed in furlongs per fortnight, we need to convert both the distance and time units to their respective values.

1 furlong is equal to 180 yards, so the horse's speed in yards per second (7 yards/second) can be converted to furlongs per second:

Speed in furlongs per second = (7 yards/second) / (180 yards/furlong) = 7/180 furlongs/second

Next, we need to convert the time from seconds to fortnights. Since a fortnight is a time period of two weeks, and there are 7 days in a week, a fortnight consists of 14 days:

Time in seconds per fortnight = (14 days/fortnight) * (24 hours/day) * (60 minutes/hour) * (60 seconds/minute) = 1,209,600 seconds/fortnight

Finally, we can calculate the horse's speed in furlongs per fortnight by multiplying the speed in furlongs per second by the time in seconds per fortnight:

Speed in furlongs per fortnight = (7/180 furlongs/second) * (1,209,600 seconds/fortnight) = 46,080/180 furlongs/fortnight ≈ 256 furlongs/fortnight

The race horse's speed is approximately 256 furlongs per fortnight.

Answer:

The leading term of the given polynomial equation is (0.1)x³ ⇒ (B)

Step-by-step explanation:

To find the polynomial equation from its graph search about

From the given graph

∵ There are three x-intercepts (-2, 0), (0, 0), (4, 0)

→ That means the polynomial equation has 3 factors use the

   x-intercepts to find them

∵ The x intercept is (-2, 0)

∴ x = -2

→ Add 2 to both sides

∴ x + 2 = -2 + 2

∴ x + 2 = 0

→ That means the equation has a factor (x + 2)

∴ (x + 2) is a factor of the given polynomial equation

∵ The x intercept is (4, 0)

∴ x = 4

→ Sutract 4 from both sides

∴ x - 4 = 4 - 4

∴ x - 4 = 0

→ That means the equation has a factor (x - 4)

∴ (x - 4) is a factor of the given polynomial equation

∵ The x intercept is (0, 0)

∴ x = 0

∴ x is a factor of the given polynomial equation

→ To find the polynomial multiply its factors

∴ y = x( x + 2)(x - 4)

∵ The leading term is the first term

∵ x(x)(x) = x³ is the first term when we multiply the 3 factors

∴ The leading term is x³

→ The choices have (0.1)x³

∴ y = 0.1x(x + 2)(x - 4)

∴ The leading term of the given polynomial equation is (0.1)x³

The statement which is not true is c. 19 = 13 + 5

An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.

The given statements are,

A. 7 + 7 = 19 - 5

B. 9 + 9 = 11 + 7

C. 19 = 13 + 5

D. 20 - 12 = 4 + 4

Taking each statement one by one,

A. 7 + 7 = 19 - 5

So, L.H.S. = 7 + 7 = 14

and R.H.S. = 19 -5 = 14

Thus, L.H.S = R.H.S

Therefore the statement is true.  

B. 9 + 9 = 11 + 7

So, L.H.S. = 9 + 9 = 18

and R.H.S. = 11 + 7 = 18

Thus, L.H.S = R.H.S

Therefore the statement is true.  

C. 19 = 13 + 5

So. So, L.H.S. = 19

and R.H.S. = 13 + 5 = 18

Thus, L.H.S ≠ R.H.S

Therefore the statement is not true.

D. 20 - 12 = 4 + 4

So, L.H.S. = 20 - 12 = 8

and R.H.S. = 4 + 4 = 8

Thus, L.H.S = R.H.S

Therefore the statement is true.  

Thus, the statement which is not true is c. 19 = 13 + 5.

Answer:

Group B.

Step-by-step explanation:

Magna Carta is considered as one of the most document in the history of England. The document was signed by King John on June 15, 1215. The document was a result of barons who stood in oppose to the King and forced him to write this document restricting the right's of the Crown. There are total 63 clauses in the document.

The set of group that describes basic principes of the Magna Carta is Group B. The document bestows churches the rights to chose their leaders without any interference from the King. These rights, according to the document were not to be taken away from the church. This principle can be found in Clause 1 of the document. Another Clause that permits freeman and merchants of continue making their livelihood can be found in Clause 20. Clause 20 permits freeman and merchants to exercise their livelihood even after they were punished. And, Clause 54, of the document gave woman rights to make an appeal to arrest only if their husbands were murdered.

Therefore Group B is the correct answer.

Step-by-step explanation:

On average, 7th grade girls tend to be about 5 inches taller than 4th grade girls. The correct choice is the statement "On average, 7th grade girls tend to be about 5 inches taller than 4th grade girls" is true.

Explanation: Given the data for ten 4th grade girls and ten 7th grade girls with their heights recorded in inches, we need to determine whether the given statement is true or false. Here are the heights of 4th grade girls:57, 60, 53, 59, 54, 55, 59, 57, 56, 55.Here are the heights of 7th grade girls:63, 64, 65, 64, 69, 61, 65, 63, 67, 67.The average height of 4th grade girls is calculated as follows:

Total height of 4th grade girls = 57 + 60 + 53 + 59 + 54 + 55 + 59 + 57 + 56 + 55 = 565.

Average height of 4th grade girls = Total height of 4th grade girls / Number of 4th grade girls= 565 / 10 = 56.5.

So, the average height of 4th grade girls is 56.5 inches.

The average height of 7th grade girls is calculated as follows:

Total height of 7th grade girls = 63 + 64 + 65 + 64 + 69 + 61 + 65 + 63 + 67 + 67 = 658.

Average height of 7th grade girls = Total height of 7th grade girls / Number of 7th grade girls= 658 / 10 = 65.8.

So, the average height of 7th grade girls is 65.8 inches. On average, 7th grade girls tend to be about (65.8 - 56.5) = 9.3 inches taller than 4th grade girls.

Answer:

facts and statistics collected together for reference or analysis

a piece of information :)

Step-by-step explanation:

The transformation T preserves the answer: if G has a k-clique, then G' has a k-independent set, and vice versa.

a) **Problem Definition: K-Independent Set**

A k-independent set is a subset of vertices in a graph such that no two vertices in the set are adjacent (i.e., there is no edge connecting them). Formally, given an undirected graph G = (V, E), a k-independent set S is a subset of V where for every pair of vertices u and v in S, there is no edge (u, v) in E. The goal is to find the largest k-independent set in the given graph.

b) **Brute Force Method for Solving K-Clique**

The brute force method for solving the k-clique problem involves examining every possible subset of k vertices in the graph and checking if each subset forms a complete subgraph (clique) of size k. If the size of the graph is n and k is constant, then the number of possible subsets to examine is a polynomial function of n. Thus, the brute force method runs in polynomial time when k is constant.

However, when k=n/2, the brute force method becomes inefficient. The number of subsets of k vertices to examine becomes 2^n/2, which grows exponentially with the size of the input graph. This exponential growth makes the brute force method impractical for larger values of n.

c) **Transformation from K-Clique to K-Independent Set**

To transform an instance of the k-clique problem to the k-independent set problem, we define the following polynomial-time transformation T:

Given an instance of k-clique G = (V, E), construct a new graph G' = (V, E'), where E' consists of all the edges in G that are not in E. In other words, the edges in G' are complementary to the edges in G.

The transformation T is polynomial-time because constructing G' from G can be done in polynomial time since the size of E' is at most the size of E.

**Proving T is Polynomial-Time:**

The transformation T runs in polynomial time because constructing G' from G requires checking each edge in E, which can be done in polynomial time.

**Proving T is Answer-Preserving:**

Let C be a clique of size k in G. If we apply the transformation T to G and obtain G', then the vertices in C will not be adjacent in G', as they form a clique in G. Hence, C becomes a k-independent set in G'.

Conversely, if S is a k-independent set in G', then the vertices in S are not adjacent in G'. This means that there is no edge connecting any pair of vertices in S in G'. Thus, S forms a clique of size k in G.

Therefore, the transformation T preserves the answer: if G has a k-clique, then G' has a k-independent set, and vice versa.

In conclusion, the transformation T from k-clique to k-independent set is polynomial-time and answer-preserving.

Step-by-step explanation:

Solving by completing square

The reliability of component B in the equipment system can be calculated based on the given information that the probability of system failure is 0.003 and component A has a reliability of 0.998.

The reliability of a system is the probability that it will function without failure over a specified period. In this case, the system will fail if either component A or B fails. Let's denote the reliability of component B as R(B). The probability of system failure is equal to the complement of the reliability, so we have:

Probability of failure = 1 - R(B) = 0.003.Given that the reliability of component A is 0.998, we know that the system will only fail if both components A and B fail simultaneously. Since the system failure probability is very low (0.003), we can assume that the probability of both components failing together is negligible.

Probability of failure = Probability of failure of A * Probability of failure of B. Since the probability of failure of A is negligible compared to the system failure probability, we can simplify the equation as: 1 - R(B) ≈ 0.003. Solving for R(B), we find: R(B) ≈ 1 - 0.003 = 0.997

Answer:

John waited for Brain at the finish line for a half-hour. (or 30 minutes)

Step-by-step explanation:

The rule of the distance is D = s × t, where

Let us use this rule to solve the question

∵ John's speed = 10 miles/hour

∵ Brian's speed = 8 miles/hour

→ Slower speed takes more time

∵ The distance of the trip is 20 miles

∴ D = 20 miles

→ Find the time of each one, using the rule above

∵ D = s × t

→ Find John's time

∴ 20 = 10 × t

∴ 20 = 10t

→ Divide both sides by 10

∴ 2 = t

∴ John's time = 2 hours

→ Find Brian's time

∴ 20 = 8 × t

∴ 20 = 8t

→ Divide both sides by 8

∴ 2.5 = t

∴ Brain's time = 2.5 hours

→ Subtract their times to find for how long John waited

∵ 2.5 h - 2 h = 0.5 h

∴ The difference between their times is 0.5 hour

∴ John waited for Brain at the finish line for a half-hour (or 30 minutes)
