Answer:

A

Step-by-step explanation:

Well, this isn't too hard.

Since the left is the negative side (R) and the right is the positive side (S), a positive and a negative with the same number will equal zero if only one of them are negative.

You ALWAYS subtract when there's two different signs.

To know about the relationship between a low alpha level (a) and the power of a statistical test. If you choose a very low alpha level, close to zero, then the correct option is:

b. the test will have very low power.

When you set a very low alpha level, it means that you are being very strict about rejecting the null hypothesis, so you will need very strong evidence to do so. As a result, the chances of committing a Type II error (failing to reject a false null hypothesis) increases, which in turn decreases the power of the test. The power of a test is the probability of correctly rejecting the null hypothesis when it is indeed false.

To explain further, power is influenced by several factors, including sample size, effect size, and alpha level. A low alpha level means that the critical region is smaller, and the probability of rejecting a true null hypothesis is reduced. This, in turn, leads to a higher probability of failing to reject a false null hypothesis, resulting in low power. In contrast, a higher alpha level will increase the power of the test, but it also increases the likelihood of committing a Type I error (rejecting a true null hypothesis). Therefore, choosing the appropriate alpha level for a test is crucial to achieving the desired balance between type I and type II error rates and maximizing the power of the test.

Answer:

  (13, 16)

Step-by-step explanation:

Vertically, the y-coordinate of point C is midway between those of points A and B:

  Cy = (Ay +By)/2 = (2 +30)/2 = 16

Point C is at the opposite corner of two squares from point B, so the x-coordinate of point C will be the same amount less than B's x-coordinate as C's y-coordinate is from B's.

  Cx = Bx -(By -Cy)

  Cx = 27 -(30 -16) = 27 -14

  Cx = 13

The coordinates of point C are (Cx, Cy) = (13, 16).

We have the following function

Where x is the number of days and f(x) is the corresponding rent.

The domain is all the possible values for x (number of days )

Now we know that you cannot rent for a fractional number of days or negative number of days so option D is straight away incorrect since real numbers also include integers and rational numbers.

The number of possible days must be discrete like 0, 1, 2, 3 and so on

So, option B makes complete sense for the domain of this function.

The domain of the function is

Note that option A (x ≥ 0) suggests that the numbers of days may also be decimal like 0.15, 1.23 etc. so it is also incorrect.

Also, option C is the range of the function that is possible values of rent f(x) so it is also incorrect.

The probability of getting doubles or a sum of 6, given that at least one die shows 2, is 1/6.

To solve this problem, we need to consider two events: Event A, which represents getting doubles (both dice showing the same number), and Event B, which represents getting a sum of 6.

Getting doubles: There are 6 possible outcomes for doubles (1-1, 2-2, 3-3, 4-4, 5-5, and 6-6) out of the total 36 possible outcomes when rolling two dice (6 outcomes for the first die multiplied by 6 outcomes for the second die). Therefore, the probability of getting doubles is 6/36, which simplifies it to 1/6.

Getting a sum of 6: There are five possible outcomes that give a sum of 6: (1-5, 2-4, 3-3, 4-2, and 5-1). Again, considering the total of 36 possible outcomes, the probability of getting a sum of 6 is 5/36.

Now, we need to find the probability of getting doubles or a sum of 6, given that at least one die shows 2. This means we have three favorable outcomes: (2-2 for doubles, 1-5, and 2-4 for a sum of 6), out of a total of 11 possible outcomes where at least one die shows 2.

To calculate the probability, we divide the number of favorable outcomes (3) by the total number of possible outcomes (11), resulting in a probability of 3/11.

Therefore, the final probability of getting doubles or a sum of 6, given that at least one die shows 2, is 3/11, which simplifies to approximately 0.273 or 27.3%.

To graph y = x² + 4x + 6 with 5+ points using an x/y chart, follow these steps:

Step 1: Create an x/y chart with five rows and two columns. Label the first column x and the second column y.

Step 2: Choose five values for x. You can choose any values you want as long as you plug them into the equation in the next step. In this example, we will use -3, -2, -1, 0, and 1. Write these values in the first column of your chart.

Step 3: Plug each value of x into the equation y = x² + 4x + 6 to find the corresponding value of y. Write these values in the second column of your chart. To make it simpler, here are the calculations for each point:When x = -3: y = (-3)² + 4(-3) + 6 = 3When x = -2: y = (-2)² + 4(-2) + 6 = 2When x = -1: y = (-1)² + 4(-1) + 6 = 1When x = 0: y = (0)² + 4(0) + 6 = 6When x = 1: y = (1)² + 4(1) + 6 = 11

Step 4: Plot each point on the x/y chart. The x value goes on the horizontal axis (x-axis) and the y value goes on the vertical axis (y-axis). Once you have plotted all five points, connect them with a smooth curve to create the graph of y = x² + 4x + 6. The graph is shown in the figure below.

The net of a triangular prism consists of two triangles and three rectangles.

In the net of a triangular prism, we can observe two types of polygons: triangles and rectangles.

First, let's discuss the triangles.

A triangular prism has two triangular faces, which are congruent to each other.

These triangles are equilateral triangles, meaning they have three equal sides and three equal angles.

Each of these triangles contributes two polygons to the net, one for each face.

Next, we have the rectangles.

A triangular prism has three rectangular faces that connect the corresponding sides of the triangular bases.

These rectangles have opposite sides that are parallel and equal in length.

Each rectangle contributes one polygon to the net, resulting in a total of three rectangles.

To summarize, the net of a triangular prism consists of two equilateral triangles and three rectangles.

The triangles represent the bases of the prism, while the rectangles form the lateral faces connecting the bases.

Altogether, there are five polygons in the net of a triangular prism.

It's important to note that the dimensions of the polygons may vary depending on the specific size and proportions of the triangular prism, but the basic shape and number of polygons remain the same.

The mass of the ball is 278.1 g, the material used to make the ball must be brass which having density of 8.6 g/cm³.

To determine the material used to make the ball, we need to first calculate the volume of the ball.

The volume of a sphere with radius r is given by:

V = (4/3) * π * r^3

Plugging in the given values, we get:

V = (4/3) * π * (2 cm)^3

= (4/3) * π * 8 cm^3

= (4/3) * 8π cm^3

= 32π cm^3

We can then use the density of each material (given in g/cm³) to calculate the mass of the ball if it were made of that material:

Copper: 8.3 g/cm³ * 32π cm³ = 266.4 g

Brass: 8.6 g/cm³ * 32π cm³ = 275.2 g

Iron: 7.8 g/cm³ * 32π cm³ = 250.4 g

Since the mass of the ball is 278.1 g, the material used to make the ball must be brass.

The probability of not enough seats being available when Air-USA books 17 persons is 0.17. This probability is not low enough to alleviate concerns for passengers, whether we define unusual as 5% or 10%.

The probability of not having enough seats available when Air-USA books 17 persons can be calculated by considering the percentage of booked passengers who actually arrive for the flight. Since past studies reveal that only 83% of the booked passengers actually arrive, we can calculate the probability as follows:

Probability = 1 - Percentage of passengers who arrive

          = 1 - 0.83

          = 0.17

Therefore, the probability that not enough seats will be available is 0.17.

To determine if this probability is low enough to not be a concern for passengers, we need to compare it with the defined threshold of "unusual" events. If we define unusual as 5% or less, then the probability of 0.17 is higher than the threshold. Therefore, if we define unusual as 5% or less, the probability is not low enough to not be a concern for passengers.

However, if we define unusual as 10% or less, then the probability of 0.17 is still higher than the threshold. Therefore, even with a higher threshold, the probability is still not low enough to not be a concern for passengers.

In conclusion, regardless of whether we define unusual as 5% or 10%, the probability of not enough seats being available is not low enough to alleviate concerns for passengers.

The cost of walking this guest is $190.

The cost of walking the guest can be calculated by adding up the expenses incurred by the hotel.

The guest was walked to another hotel that charged a room rate of $150. Therefore, the hotel incurred a cost of $150 for the room.

In addition to the room cost, the hotel also paid for the guest's Uber ride to the new hotel, which was $15.

Furthermore, the overbooked hotel gave the guest a gift card worth $25. Although the gift card does not directly represent an expense, it can be considered as an opportunity cost for the hotel, as they could have used that money to cover other costs.

Part B: A closed circle on a number line represents an included value, indicating that the endpoint is part of the solution set of the inequality. It is used when the inequality includes the symbols ≤ (less than or equal to) or ≥ (greater than or equal to), which denote inclusive inequality.

Part C: The shading on the number line represents the range of values that satisfy the given inequality. It indicates which values make the inequality true. Typically, the shading is done to the right or left of the circle(s) depending on whether the inequality is greater than or less than.

Part A:

For example, if we have the inequality x > 2, we would represent it with an open circle at 2 on the number line. This means that 2 itself is not a valid solution, but any value greater than 2 is included.

Part B:

For example, if we have the inequality x ≥ -3, we would represent it with a closed circle at -3 on the number line. This means that -3 itself is a valid solution, as well as any value greater than or equal to -3.

Part C:

For example, if we have the inequality x > 2, we would shade the portion of the number line to the right of the open circle at 2. The shaded region represents all the values greater than 2 that satisfy the inequality.
