A demand that is completely inelastic is one in which a change in price has no impact on the quantity demanded. The demand curve in this situation is vertical, and there is no demand elasticity.

A demand curve in economics is a graph showing the relationship between the price of a specific good (the y-axis) and the amount of that good that is desired at that price (the x-axis). Demand curves can be applied to both the price-quantity relationship for a single consumer (an individual demand curve) and for all consumers in a specific market.

Demand curves are typically thought to slope downward, as the adjacent image illustrates. This is due to the law of demand, which states that for the majority of goods, the quantity demanded decreases as the price increases. This law does not apply in some peculiar circumstances. These include Veblen goods, Giffen goods, and speculative bubbles, in which consumers are drawn to a commodity if its price increases.

The approximate probability that someone might answer the next call E.J. makes is 0.25 or 25%. The correct answer is C. 0.25.

To find the approximate probability that someone might answer E.J.'s next call, we'll use the information provided and follow these steps:

1. Calculate the total number of calls made: answered calls (40) + unanswered calls (120).
2. Find the proportion of answered calls to the total calls.
3. Express the proportion as a probability (as a percentage or fraction).

Let's do the calculations:

1. Total calls = 40 (answered) + 120 (unanswered) = 160 calls
2. Proportion of answered calls = 40 answered calls / 160 total calls = 1/4
3. Probability = 1/4 = 0.25 (as a decimal) or 25% (as a percentage)

So, the approximate probability that someone might answer the next call E.J. makes is 0.25 or 25%. The correct answer is C. 0.25.

Answer:

21 is your answer

Step-by-step explanation:

The combination formula is used to calculate the number of ways to choose r items from a set of n items without regard to order. The formula is:

C(n,r) = n! / (r! * (n-r)!)

where n is the total number of items and r is the number of items to be chosen.

Using this formula, we can solve the problem when n = 7 and r = 5 as follows:

C(7,5) = 7! / (5! * (7-5)!)

= (7 x 6 x 5 x 4 x 3 x 2 x 1) / [(5 x 4 x 3 x 2 x 1) x (2 x 1)]

= (7 x 6) / (2 x 1)

= 21

Therefore, there are 21 ways to choose 5 items from a set of 7 items without regard to order.

The pattern for the sequence 8, 17, 26, 35, 44, … is 9n - 1

The pattern in the question is given as

8, 17, 26, 35, 44, …

In the above expressions and pattern, we can see that

The current term is added to 9 to get the next term

From the above, we have the following

This means that the pattern is an arithmetic sequence with the following features

a = 8

d = 9

An arithmetic sequence is represented as

f(n) = a + (n - 1)d

When the values of "a" and "d" are substituted in the above equation, we have the pattern to be

f(n) = 8 + (n - 1)9

So, we have

f(n) = 8 + 9n - 9

Evaluate

f(n) = 9n - 1

Hence, the pattern for the sequence is 9n - 1

The resulting score equations imply that the residual vector e = y - û is orthogonal to the column space of X, indicating that the residuals are uncorrelated with the predictors.

In a generalized linear model (GLM) with a canonical link function, the likelihood function can be written as:

L(β) = ∏[f(yi; μi)]^wi

where β is the vector of regression coefficients, yi is the observed response for the ith observation, μi is the corresponding mean response, wi is the weight associated with the ith observation, and f is the probability density function of the response distribution.

The maximum likelihood estimates of the regression coefficients can be obtained by solving the score equations, which are given by:

XᵀW(y-μ) = 0

where X is the design matrix of the model, W is a diagonal matrix of the weights, and μ is the vector of mean responses, which are related to the linear predictor by the link function.

Let e = y - û be the vector of residuals, where û = Xβ is the vector of fitted means. Then, we can rewrite the score equations as:

XᵀWe = XᵀW(y-û) = XᵀW(y-Xβ) = XᵀW(y-X(XᵀWX)^(-1)XᵀW y) = 0

where we have used the fact that X(XᵀWX)^(-1)XᵀWX = XᵀWX and X(XᵀWX)^(-1)XᵀW = I, where I is the identity matrix.

This implies that XᵀWe = 0, which means that the residual vector e is orthogonal to the column space of X. In other words, the residuals are uncorrelated with the predictors, which is a desirable property of the model.

This result can be interpreted geometrically as follows: the residual vector e lies in the orthogonal complement of the column space of X, which is the space spanned by the null space of Xᵀ. Therefore, the projection of e onto the column space of X is zero, which means that the residuals do not contain any information about the predictors that is not already captured by the fitted means.

The formula for the time taken by two people to complete a task together indicates;

The formula for completing a task by two persons, A and B can be presented as follows;

Time taken by A and B together = 1/(A's work rate + B's work rate)

A's work rate = 1/A's time

B's work rate = 1/B's time

Time taken by A and B together = 1/(1/A's time + 1/B's time)

1/(1/A's time + 1/B's time) = (A's time × B's time)/(A's time + B's time)

Time by A and B together = (A's time × B's time)/(A's time + B's time)

The number of days A can do the specified work = 30m days

The number of days it will take B to do the same work = 60m days

The number of days it will take A and B combined to do the same work can therefore be found as follows;

A's work rate = 1/30

B's work rate = 1/60

The combined work rate = (1/30) + (1/60) = (2 + 1)/60 = 1/20

The number of days it will take A and B to do the work together = 1/(Their combined work rate) = 1/(1/20) = 20 days

P can do the a work in 40 days, therefore, P's work rate = 1/40

Q can do the work in 60 days, therefore, Q's work rate = 1/60

Their combined work rate = (1/40) + (1/60) = (3 + 2)/120 = 1/24

Therefore, P and Q will finish the work together in 1/(1/24) = 24 days

Face-centered tetragonal lattices are not listed among the 14 3D Bravais lattices because they can be described as a combination of two different Bravais lattices: the simple tetragonal lattice and the face-centered cubic lattice.

To understand why, let's consider the definition of a face-centered tetragonal lattice. It is characterized by a rectangular prism with edges of equal length and right angles between them. Additionally, it has lattice points at the corners of the prism and one additional lattice point at the center of each face.

However, this arrangement can be described as a combination of a simple tetragonal lattice and a face-centered cubic lattice.

The simple tetragonal lattice consists of lattice points only at the corners of the rectangular prism, while the face-centered cubic lattice has lattice points at the corners and one additional lattice point at the center of each face.

By combining these two lattices, we can obtain a structure that satisfies the conditions of a face-centered tetragonal lattice.

Therefore, the face-centered tetragonal lattice is not considered as a separate Bravais lattice but rather as a composite of the simple tetragonal and face-centered cubic lattices.

Here is a sketch to illustrate the arrangement:

```

       o-------o-------o

      /                   /

   /       o          /

 /                   /

o-------o-------o

```

The solid circles represent lattice points, and the lines represent the unit cell. The corners of the rectangular prism correspond to lattice points from the simple tetragonal lattice, while the centers of the faces correspond to lattice points from the face-centered cubic lattice. Together, they form the face-centered tetragonal arrangement.

By recognizing that face-centered tetragonal lattices can be described using a combination of simpler lattices, the need to list them as a separate 3D Bravais lattice is eliminated.

The correct answer is "half the width of the confidence interval."

The margin of error of a confidence interval about the difference between the means of two populations is equal to half the width of the confidence interval.

In a confidence interval, the width represents the range between the upper and lower bounds of the interval. The margin of error indicates the maximum amount by which the sample estimate can deviate from the true population parameter.

To calculate the margin of error, you divide the width of the confidence interval by 2. This is because the margin of error represents the distance from the sample estimate to the upper or lower bound of the interval. By dividing the width by 2, we determine the maximum amount of deviation from the estimate allowed on either side.

Therefore, the correct answer is "half the width of the confidence interval."

Answer:

-2.41

Step-by-step explanation:

rearrange:

12x + 10 + 5x + 31

Or

12x + 5x + 10 + 31

Simplify and set that is = to zero so we can isolate x

17x + 41 = 0

To solve for x, we can isolate x on one side of the equation by subtracting 41 from both sides:

17x = -41

Finally, we can solve for x by dividing both sides by 17:

x = -41/17

therefore, x is equal to approximately -2.41 when we plug it back into the original equation:

12x + 10 + 5x + 31 = 0

12(-2.41) + 10 + 5(-2.41) + 31 = 0
