The statements which are true for the graph of a line with negative slope are D and E.

Given a graph of a line with a negative slope.

We have to find the statements which are true for the graph with negative slope.

For a graph with negative slope, the line will be moving from up to down.

The line goes down from left to right.

So B is not true and E is true.

Also, if the slope gets bigger, the graph of the line will get steeper.

That is, as the absolute value of the negative slope gets smaller, the graph of the line gets less steep.

Hence the true statements are D and E.

The monthly cost of a short-term disability insurance policy varies directly with the salary of the employee. Given that Wanda's monthly cost is $16.75 with an annual salary of $33,500, we can calculate Randy's expected monthly cost for his policy, knowing his annual salary is $45,500.

To determine Randy's expected monthly cost for his policy, we can use the concept of direct variation. Direct variation means that two variables are related in a way that can be represented by a constant ratio. In this case, the monthly cost and the salary are directly proportional.

We can set up a proportion using the given information:

(16.75 / 33,500) = (x / 45,500)

To solve for x, the monthly cost for Randy's policy, we can cross-multiply and solve for x:

16.75 * 45,500 = 33,500 * x

x = (16.75 * 45,500) / 33,500

Calculating this expression will give us Randy's expected monthly cost for his policy.

Another important mathematical contribution made by Fibonacci (Leonardo of Pisa) is the introduction of the Hindu-Arabic numeral system and its adoption in Western mathematics.

During the 13th century, Fibonacci traveled extensively and encountered the numeral system used in India and the Arab world, which is based on the concept of place value. Recognizing its efficiency and advantages over the existing Roman numeral system, Fibonacci popularized the Hindu-Arabic numeral system in Europe through his influential book "Liber Abaci" (Book of Calculation) published in 1202.

The Hindu-Arabic numeral system, which includes the use of the digits 0-9 and the concept of positional notation, revolutionized arithmetic and made calculations much simpler and more efficient. It introduced the concept of using place value to represent numbers, allowing for complex calculations to be performed with ease. This numeral system formed the foundation of modern arithmetic and laid the groundwork for the development of algebra and other branches of mathematics.

Fibonacci's introduction and promotion of the Hindu-Arabic numeral system had a profound impact on mathematics, commerce, and scientific endeavors. It enabled advancements in fields such as astronomy, engineering, and finance, making complex calculations more accessible and accurate. Fibonacci's contribution played a crucial role in the development of mathematics and its practical applications, and it remains a significant part of our everyday numerical representation and calculation systems today.

The number expression (-5)⁵/(-5)⁻⁶ can be written as -5¹¹ after using the property of the integer exponent.

In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.

We have:

A number expression:

= (-5)⁵/(-5)⁻⁶

As we know from the property of the integer exponent:

\(\rm = \dfrac{y^a}{y^b} = y{a-b}\)

y is the base and a, b are the exponent.

As the same base can be written as the sum of the power

In the given number expression there is the same base as -5

Exponent can be subtracted, after subtracting the powers:

= (-5)⁵⁻⁽⁻⁶⁾

= (-5)⁵⁺⁶

= -5¹¹

Thus, the number expression (-5)⁵/(-5)⁻⁶ can be written as -5¹¹ after using the property of the integer exponent.

The mean of the fitted exponential distribution is 66.67.

To find the mean of the fitted exponential distribution, we first need to estimate the parameter lambda using maximum likelihood estimation.

The probability density function of the exponential distribution is given by

f(x; lambda) = lambda * exp(-lambda * x)

where x is the claim size and lambda is the parameter to be estimated.

The likelihood function for the observed data is the product of the individual probabilities of each claim

L(lambda) = lambda^n * exp(-lambda * sum(x_i))

where n is the number of observed claims and x_i is the i-th claim size.

The log-likelihood function is given by:

ln L(lambda) = n * ln(lambda) - lambda * sum(x_i)

To estimate the parameter lambda, we need to maximize the log-likelihood function with respect to lambda:

d/d(lambda) ln L(lambda) = n/lambda - sum(x_i) = 0

Solving for lambda, we get

lambda = n / sum(x_i)

Substituting the observed values, we get

lambda = 6 / (20 + 45 + 50 + 80 + 100 + 2*100) = 0.015

Therefore, the estimated parameter of the fitted exponential distribution is lambda = 0.015.

The mean of the exponential distribution is given by

E(X) = 1/lambda

Substituting the estimated value of lambda, we get

E(X) = 1/0.015 = 66.67

The function rule that could model this situation is f(x)=sin(x)+3. The correct answer is (c).

The sine function is a mathematical function that describes a periodic oscillation. It is one of the basic trigonometric functions, along with cosine, tangent, cotangent, secant, and cosecant.

Let us relate this to our given question.

The midline of a sine function is the horizontal line that the graph oscillates around.

In this case, the midline is y=3, which means that the sine function oscillates between y=3+1=4 and y=3-1=2.

The function rule that could model this situation is c. f(x)=sin(x)+3, because adding 3 to the sine function shifts the midline up to y=3, and the sine function oscillates between y=4 and y=2.

AC = BD and AB = BC = CD = DA

We also know that DE = EB, which means that triangle ADE is congruent to triangle BEC (by the side-side-side congruence rule), so we have:

AD = BC and AE = EC

AD=5cm and DC=4cm

Combining these equations, we have:

AC = AD + DC

Statement (c) is correct for a simple graph. Every trail is a path, and every path is a trail.

In graph theory, a simple graph is an undirected graph with no loops or multiple edges between the same pair of vertices. A path in a graph is a sequence of vertices where each consecutive pair is connected by an edge. A trail in a graph is a path that allows for repeated vertices and edges.

Statement (a) is not correct because not every path is a trail. A path does not allow for repeated vertices or edges, whereas a trail does.

Statement (b) is not correct because not every trail is necessarily a path. A trail may contain repeated vertices or edges, but a path does not.

Statement (d) is not correct because paths and trails do have a relation. A trail is a more general concept that encompasses paths by allowing for repetition of vertices and edges.

Therefore, statement (c) is the correct statement. In a simple graph, every trail is a path, and every path is a trail.

Answer: x = 6

Step-by-step explanation:

Because we are given that the two figures are already similar, we can set up a proportional relationship to determine the value of x. Since the larger rectangle has a width of 21 and the smaller rectangle has a width of 7, those values can be used as the numerators in the proportion. Since the larger rectangle's length is x plus the additional 3 units on the smaller rectangle, x+3 and 3 can be used as the denominators in the proportion.

Next, we set up the proportion as follows:

\(\frac{21}{x+3} =\frac{7}{3}\)

Then, you cross multiply to get the equation:

\(63=7x+21\)

After solving down algebraically, you get the value of x to be 6.

The probability that it takes the player 2 tries to make a three-point shot is approximately 0.217.

To find the probability that it takes player 2 tries to make a three-point shot, we can use the concept of geometric probability.

The probability of making a three-point shot on any single attempt is 0.682. Therefore, the probability of missing a shot on a single attempt is 1 - 0.682 = 0.318.

Since we are interested in the player making the shot on the second attempt, we need to consider the following sequence of events:

1. Missing the shot on the first attempt (probability of 0.318).

2. Making the shot on the second attempt (probability of 0.682).

To find the probability of these events occurring in sequence, we multiply their probabilities together:

0.318 * 0.682 = 0.217276

Students were surveyed about their favorite colors. 1/4 of the student preferred red, 1/8 of the students preferred blue, and 3/5 of the remaining students preferred greed, then 10 students surveyed did not choose a rainbow color as their favorite.

Let's use algebra to solve for the total number of students surveyed:

Let x be the total number of students surveyed.

Then, the number of students who preferred red is (1/4)x.

The number of students who preferred blue is (1/8)x.

The remaining students are (x - (1/4)x - (1/8)x) = (5/8)x.

Out of these remaining students, 3/5 preferred green, so we can set up the equation:

(3/5)(5/8)x = 15

Simplifying, we get:

(3/8)x = 15

Multiplying both sides by 8/3, we get:

x = 40

Therefore, there were 40 students surveyed in total. To find the number of students who did not choose a rainbow color as their favorite, we need to subtract the number of students who preferred red, blue, green, or purple from the total number of students:

Number of students who did not choose a rainbow color = x - (1/4)x - (1/8)x - 15 = 40 - 10 - 5 - 15 = 10

Therefore, 10 students surveyed did not choose a rainbow color as their favorite.

The price of the new drink in the long run, under a Bertrand duopoly, would be $9.

In a Bertrand duopoly, each firm sets its price based on the assumption that the competitor will match it. The firms engage in price competition, trying to undercut each other to gain a larger market share. Eventually, this competition drives prices down to the level of marginal cost.

Assuming both firms have the same marginal cost, they would set their prices equal to marginal cost to maximize their profits. In this scenario, the marginal cost is not provided, so we'll consider it as a constant value.

Let's assume the marginal cost is $6. Each firm wants to set a price lower than its competitor to attract more customers. Since the competitor's price is unknown, each firm will assume the worst-case scenario, where the competitor sets the price at its marginal cost of $6. To gain market share, each firm will set its price slightly below $6.

Let's assume Firm A sets its price at $5.99. Firm B, anticipating this, will set its price slightly lower. Assuming a minimal difference of $0.01, Firm B will set its price at $5.98. This process continues until both firms converge to the marginal cost.

In the long run, the price will stabilize at the marginal cost of $6. Therefore, the price of the new drink in the long run would be $6.

In a Bertrand duopoly, with the provided assumptions, the price of the new drink in the long run would be $6. This result is based on the assumption that both firms have the same marginal cost and engage in price competition, undercutting each other to gain market share.
