When x is correlated with y, it means that there exists a relationship between the two variables, where a change in one variable (x) is associated with a change in the other variable (y).

This relationship can be either positive or negative.

In a positive correlation, as the value of x increases, the value of y also increases, and as the value of x decreases, the value of y decreases as well. This indicates that both variables move in the same direction. On the other hand, in a negative correlation, as the value of x increases, the value of y decreases, and as the value of x decreases, the value of y increases. This shows that the variables move in opposite directions.

It is essential to note that correlation does not imply causation. Just because two variables are correlated does not mean that one variable causes the other to change. There could be other factors or variables that influence the observed relationship between x and y. Additionally, the strength of the correlation can vary, with values close to 1 or -1 representing a strong relationship and values close to 0 representing a weak relationship or no relationship at all.

In conclusion, when x is correlated with y, it means that there is a relationship between the two variables that can be either positive or negative, but this does not necessarily imply causation. The strength of the relationship can also vary, depending on the correlation coefficient value.

Answer: i think the awnser to your question is A  real number

Step-by-step explanation:

Taking the absolute value of a number, whether it's negative or positive, always returns either a positive value or zero.

Let's say we have a number line with the point A on it. Think of the absolute value of A as the distance between point A and zero. Since the distance cannot be negative, the absolute value will always return a positive value.

A positive number is always greater than zero, and zero is equal to zero. Therefore, the answer is True.

Answer:

  obtuse

Step-by-step explanation:

You may remember that side lengths of 3, 4, 5 make a right triangle. Doubling those lengths to 6, 8, 10 will still give a right triangle.

The given triangle has a longest side (11) longer than would be appropriate for a right triangle (10), so the largest angle is larger than 90°.

The triangle is obtuse.

__

Comparison of a triangle to a right triangle with two sides the same is one of several ways the triangle can be classified. You can use the Law of Cosines to find the largest angle, or you can use a triangle solver (as we have below).

In case you don't recall that 3-4-5 makes a right triangle, you can use the Pythagorean theorem to find the longest side of a right triangle with the given shorter sides:

  hypotenuse = √(6² +8²) = √100 = 10

Your long side is longer, so your largest angle is larger than 90°.

Law of Cosines:

  angle = arccos((6² +8² -11²)/(2·6·8)) = arccos(-21/96) ≈ 102.6°

Answer:

the equation that explains the relationship between BC and B"C" is:

BC = 2 * B"C"

This equation states that the length of BC is equal to twice the length of B"C".

Step-by-step explanation:

If triangle A"B"C" is formed using the translation (x+1,y+1) and the dilation by a scale factor of 3 from the origin, then the coordinates of the vertices of triangle A"B"C" can be expressed as follows:

A" (x+1, y+1)

B" (3x+3, 3y+3)

C" (3x+6, 3y+6)

To find the equation that explains the relationship between BC and B"C", we can use the distance formula to find the length of both segments. The distance formula is:

distance = √((x2 - x1)^2 + (y2 - y1)^2)

Where (x1, y1) and (x2, y2) are the coordinates of the two points.

Using the distance formula, we can find the length of BC as follows:

BC = √((3x - x)^2 + (3y - y)^2)

= √((2x)^2 + (2y)^2)

= √(4x^2 + 4y^2)

= 2√(x^2 + y^2)

We can also find the length of B"C" as follows:

B"C" = √((3x+6 - 3x-3)^2 + (3y+6 - 3y-3)^2)

= √((3)^2 + (3)^2)

= √(9 + 9)

= √(18)

= 3√(2)

A Random Variable is a defined as a variable whose value depends on the outcome of a random event.

Option (c) : the random event is the selection of 50 students from the school to measure their height. The mean height of this sample of 50 students is a random variable because it can vary depending on the specific students who are selected.

Option (a) : The true mean height of all students from your school is a population parameter and is a fixed value, so it cannot be called as a random variable.

Option (b) : The mean of the sampling distribution of mean heights for samples of size 50 is a population parameter as well, and it represents the average of all possible sample means of size 50 taken from the population. So,  it is a fixed value and not a random variable.

Answer:

Ok, suppose that a man earns X, and a woman earns Y.

if X is larger than Y, then:

((X - Y)/Y)*100% is the percentage by which the man earns more than the woman. (where Y represents the 100%)

Replacing the given values, we can see that:

X = $1200

Y = $1000

(($1200 - $1000)/$1000)*100% = ($200/$1200)*100% = 0.20*100% = 20%.

If you want the expression only in decimals then you need to ignore the 100% in the equation, and you will have:

(X - Y)/Y

($1200 - $1000)/$1000 = 0.20

This would work for any given values of X and Y.

Other way to see this is:

If the man earns X and the woman Y, then we can see at the quotient:

X/Y

For the previous values we have:

$1200/$1000 = 1.2

This means that the man earns 1.2 times what the woman earns.

If we multiply that by 100%, we have:

1.2*100% = 120%

So the man earns the 120%, which is the 100% that earns the woman plus a 20%, that is what we found before.

False. An n × n matrix that is orthogonally diagonalizable does not necessarily have to be symmetric. A matrix is said to be orthogonally diagonalizable if it can be expressed as PDP^T, where P is an orthogonal matrix and D is a diagonal matrix.

For a matrix to be symmetric, it must satisfy the condition A = A^T, where A^T denotes the transpose of A. While it is true that symmetric matrices are always orthogonally diagonalizable, the converse is not necessarily true. There exist non-symmetric matrices that can still be orthogonally diagonalized. An example of such a matrix is the following:

  [1  2]

A = [3 4]

This matrix is not symmetric, as A^T is:

  [1  3]

A^T = [2 4]

However, it is still orthogonally diagonalizable. The matrix A can be diagonalized as:

A = PDP^T, where P = [0.8507 -0.5257]

[0.5257 0.8507]

          and D = [-0.3723   0     ]

                    [ 0      5.3723]

Therefore, it is not necessary for an n × n matrix that is orthogonally diagonalizable to be symmetric.

Step-by-step explanation:

Hi there!

We are given the double inequality -7<3x+2<14 and we want to solve it.

If we have a double inequality and we want to do something (like subtract 3), then we must subtract 3 from the left side, middle, and right side.

An example would be with the inequality 1<x+3<5

In order to isolate x, we'll subtract 3 from the center. However, we'll also be needing to subtract 3 from the left (1-3) and the right (5-3)

Hence,

1<x+3<5

-3   -3  -3

___________

-2<x<2

In our problem then, we'll be subtracting 2 from EVERY side.

-7<3x+2<14

-2      -2   -2

________________

-9 < 3x  < 12

Now in order to isolate x, we'll divide by 3, which once again, we divide on EVERY side

-3<x<4

The displacement of the particle from time t=0 to time t=15 is approximately -11.37.

The displacement of the particle from time t=0 to time t=15 is given by the formula\($\Delta x = x(t_2) - x(t_1)$\). Using the given velocity function and the initial position of the particle, we can calculate the displacement of the particle from time t=0 to time t=15 as follows:
\($\Delta x = x(15) - x(0) = \into_{0}^{15} v(t) dt - 2.5 = \int_{0}^{15} cos(8e^{-0.2t}) dt - 2.5$\)
Using integration by parts, we get:
\($\Delta x = -sin(8e^{-0.2*15}) + sin(8e^{-0.2*0}) - 2.5$\)
Therefore, the displacement of the particle from time t=0 to time t=15 is given by:

The simplified expression is 2(x-2)(x-1) / (x+1).

To simplify the expression (2x-4)(x-1)/(x-3)(x+1)(x-3), we can cancel out common factors and simplify further.

First, let's cancel out common factors between the numerator and the denominator:

(2x-4)(x-1) / (x-3)(x+1)(x-3)

The numerator (2x-4) can be factored out to 2(x-2), and the denominator (x-3)(x-3) can be written as (x-3)^2:

2(x-2)(x-1) / (x-3)^2(x+1)

Now, we can check for any additional common factors that can be canceled out. The (x-3) term appears in both the numerator and the denominator, so we can cancel it out:

2(x-2)(x-1) / (x-3)(x+1)

After canceling out the common factor (x-3), we are left with:

2(x-2)(x-1) / (x+1)

Therefore, the simplified expression is 2(x-2)(x-1) / (x+1).

where r is the polar distance, e is the eccentricity, d is the distance from the focus to the directrix, and θ is the polar angle.

Since we are given a hyperbola, eccentricity e = 6, and the directrix is represented by r, we can substitute these values into the equation:

r = (6d) / (1 ± 6*cos(θ))

Data that we know:

He drove 504km in each direction.

Going, the average speed was 14km/h more than returning.

The total trip lasted 21 hours.

Ok, to solve this first:

Let's define the variables:

Sg = Average speed when going.

Sr = Average speed when returning.

Then we can write one of our relationships as:

Sg = Sr + 14km/h.

Now, you can recall the relation:

Time = Distance/speed.

Then we can write the equation that represents the total time of the travel as:

504km/Sg + 504km/Sr = 21h

Now we can replace the Sg by Sr + 14km/h, and get:

504km/(Sr + 14km/h) + 504km/Sr = 21h.

Now we must multiplacate by each denominator, in order to remove them:

504km*Sr + 504km*(Sr + 14km/h) = 21h*Sr*(Sr + 14km/h)

Sr*1008km + 7056km^2/h = 21h*Sr^2 + 294km*Sr

Now we can write a cuadratic equation, where i will ignore the units so it is easier to read, as:

21*Sr^2 -714*Sr - 7056 = 0

The solutions are given by the Bhaskara formula:

\(Sr = \frac{714 +- \sqrt{714^2 - 4*21*(-7056)} }{2*21} = \frac{714 +- 1050}{42}\)

We have two solutions, one negative and one positive, and because Sr represents an average speed, it must be a positive number, then we choose the positive solution:

Sr = (714 + 1050)/42  km/h = 42km/h

Now we have the average speed for the returning, with this we can find Sg.

Sg = Sr + 14km/h = 42km/h + 14km/h = 56km/h.

The integer represents the submarine's current location is -525 feet

The initial position of submarine = 75 feet below sea level

The descending rate of submarine = 25 feet every 10 second

Total time = 3 minutes

One minute = 60 seconds

3 minutes = 180 seconds

Therefore number of 10 seconds period = 180 / 10

= 18

For each 10 second the submarine descend 25 feet

Total distance that submarine descend = 18 × 25

The initial position of submarine = -75

Current position = -75 - 450

This is the general solution to the original differential equation, in terms of h, k, and C.

To solve the differential equation

dy/dx = (x-y-1)/(x+y+1)

       dy/dx = dv/ds + k

       x - y - 1 = h + s - v - k - 1 = s - v + (h - k - 1)

        x + y + 1 = h + s + v + k + 1 = s + v + (h + k + 1)

        dv/ds + k = [(h + s - v - k - 1) - (s - v + (h - k - 1))] / [(h + s + v + k + 1) -

        (s + v + (h + k + 1))]

       dv/ds + k = [(2h - 2k - 2)s - 2v] / [-2]

       or

       dv/ds = (v - h + k - s) / 2

        dv/ds = du/ds

        and the equation becomes:
