Answer:

147.7 meters

Step-by-step explanation:

kilo means 'thousands' so you have to move the demical 3 places to the left to make .1477 a thousand times larger

also, you could set up a proportion like the following based on 1km = 1000m

1000 m =  x  

   1 km        .1477

x = .1477 x 1000

x = 147.7

Assuming that we are starting with a pool of 8 people, we can form the committee in 8 different ways. This is because the committee must contain exactly 3 Ravenclaws, 1 Gryffindor, and 4 people from other houses.

First, we will choose 3 Ravenclaws from the 8 people. This can be done in 8 combinations. Then, we will choose 1 Gryffindor from the remaining 5 people. This can be done in 5 combinations. Lastly, we will choose 4 people from the remaining 4 people, which can be done in 4 combinations.

By multiplying the number of combinations, we get for each step, we can conclude that the total number of ways to form an 8-person committee with the requirement is 8 x 5 x 4 = 160. However, since the order of the people in the committee does not matter, this total number is reduced to 8. In conclusion, we can form the 8 person committee with the given requirement in 8 different ways.

Answer:

\(PZQ = 63\)

Step-by-step explanation:

Given

\(OZQ = 125\)

\(OZP = 62\)

Required

Determine PZQ

Since P is an interior of OZQ, we have that:

\(OZQ = OZP + PZQ\)

Solve for PZQ

\(PZQ = OZQ - OZP\)

Substitute values for OZQ and OZP

\(PZQ = 125 - 62\)

\(PZQ = 63\)

\( - 5m \: + \:10 \: > 25 \\ or \: - 5m > 25 - 10 \\ or \: - 5m > 15 \\ or \: m > \frac{15}{ - 5 } \\ or \: m \: > - 3\)

The graph that represents the situation is required.

What is graph?

A graph is a structure that resembles a set of items in discrete mathematics, more especially in graph theory, in which certain pairs of the objects are conceptually "connected." The items are represented by mathematical abstractions known as vertices, and each pair of connected vertices is referred to as an edge.

Graphs are a popular tool for graphically illuminating data connections. A graph serves the objective of presenting facts that are either too many or complex to be fully expressed in the text while taking up less room.

The correct statement is Most of the songs were between 3 minutes and 3.8 minutes long.

Based on the given information from the graph, we can determine the following:

The graph shows an upward trend from 2.8 to 3.4 on the horizontal axis.

Then, there is a downward trend from 3.4 to 4 on the horizontal axis.

From this, we can conclude that most of the songs played during the one-hour interval were between 3 minutes and 3.8 minutes long. This is because the upward trend indicates an increase in length from 2.8 to 3.4, and the subsequent downward trend suggests a decrease in length from 3.4 to 4.

Therefore, the correct statement is:

Most of the songs were between 3 minutes and 3.8 minutes long.

In order to reach the leaves of the trees, one would need to travel along the trunk and branches of the tree, and then climb up the leaves.

In order to reach the leaves of a tree, one would have to take a pathway that begins at the base of the tree. This pathway would involve climbing up the trunk of the tree, and then making their way through the branches until they reach the leaves. Depending on the size of the tree, this may require some climbing skills, or the use of special equipment. The branches of the tree provide the necessary pathways to the leaves, and the leaves themselves can be used as footholds to help with the climb. Once the leaves are reached, it is possible to survey the environment and take in the beauty of the tree.

Since angle y and angle x form vertical angles, the measure of angle x is equal to 50°.

In Geometry, the vertical angles theorem is also referred to as vertically opposite angles theorem and it states that two (2) opposite vertical angles that are formed whenever two (2) lines intersect each other are always congruent, which simply means being equal to each other.

Furthermore, the sum of the angles on a straight line is equal to 180. Therefore, we would sum up all of the angles as follows;

60° + 70° + y = 180°

130° + y = 180°

y = 180° - 130°

y = 50°

Since both angle x and angle y are vertical angles, we can logically deduce that they are congruent and as such the magnitude of angle x is equal to 50°.

Given events A and B are independent, where P(A) = 0.5 and P(B) = 0.5 The probability of A and B and to construct the complete Venn diagram for this situation

Therefore, the probability of A and B is 0.25.

Since the given events A and B are independent, then the probability of A and B will be: P(A and B) = P(A) × P(B)

Now we will substitute the given values in the above formula: P(A and B) = 0.5 × 0.5

The area of the triangle is approximately 27.71 square units.

We can use the formula for the area of a triangle given two sides and the included angle:

Area = 1/2 * |u| * |v| * sin(theta)

where |u| and |v| are the magnitudes of the vectors, and theta is the angle between them.

First, we can find the magnitude of each vector:

Next, we can find the vector difference ~u - ~v:

~u - ~v = (3-6, 3-0, 3-6) = (-3, 3, -3)

Then, we can find the magnitude of ~u - ~v:

|~u - ~v| = √((-3)² + 3² + (-3)²) = 3√(2)

Now, we can find the angle between ~u and ~v using the dot product:

theta \(= cos^{-1(2\sqrt(6))}\) ≈ 30.96 degrees

Finally, we can plug in the values to find the area:

Therefor, the area is ≈ 27.71 square units.

Answer:

Since we are using the negative integer of -1, the answer would simply be -1. This is because 1 time any number is always going to be 1.

Step-by-step explanation:

The calculated correlation coefficient (r) is approximately -0.291.

To calculate the correlation coefficient between telomere length and chronicity, we can utilize the given summary data. The correlation coefficient, often denoted as r, measures the strength and direction of the linear relationship between two variables.

Let's denote the sum of products as Σxy, the sum of squares for chronicity as Σx², the sum of squares for telomere length as Σy², and the total sample size as n.

From the given data, we have the following values:

Σxy = -8.822

Σx² = 318.817

Σy² = 2.868

n = 38

The correlation coefficient (r) can be calculated using the following formula:

r = Σxy / √(Σx² * Σy²)

Substituting the given values into the formula:

r = -8.822 / √(318.817 * 2.868)

Now, let's solve this equation step by step:

First, multiply the values inside the square root:

r = -8.822 / √(913.350956)

Next, calculate the square root:

r = -8.822 / 30.219307

Finally, divide Σxy by the square root of the product of Σx² and Σy²:

r ≈ -0.291

The presence of a negative externality causes the MSC to be higher than the MSB, which leads to the market over-producing the good. This is because producers are only taking their private costs and benefits into account, not the costs and benefits to society as a whole. The difference between the private and social optima is known as the deadweight loss. In this case, the deadweight loss is equal to the shaded triangle in the attached image.

1. This is a negative externality. We can see this by the MSC being higher than the MSB. This means that the cost to society of producing the good is higher than the benefit to society, resulting in the market over-producing the good.2. See the attached image. 3. At private decision making, we set the MSB equal to the MPC: 12-0.5Q = 2+0.5Q. Solving for Q gives Q = 8. 4. To find the socially optimal quantity, we need to set MSB equal to MSC: 12-0.5Q = 2+1.5Q. Solving for Q gives Q = 4. 5. The private and social optima are different because of the negative externality.
