Answer:

  an = 22 -6(n -1)

Step-by-step explanation:

The first term of the sequence is given as a1 = 22. The general term of an arithmetic sequence is ...

  an = a1 +d(n -1) . . . . n-th term for first term a1 and common difference d

The third term will be ...

  a3 = 10 = 22 +d(3 -1)

Then the common difference is ...

  10 -22 = 2d

  -12/2 = d = -6

__

Putting the known values into the formula for the general term, it becomes ...

  an = 22 -6(n -1)

__

This can be simplified to ...

  an = 28 -6n

Freud is a stage theorist. Sigmund Freud, the renowned Austrian neurologist and psychoanalyst, is widely recognized as one of the pioneers in the field of psychoanalysis.

He proposed a developmental theory that included psychosexual stages of development. According to Freud, human development progresses through distinct stages, each characterized by a specific focus on different erogenous zones. These stages include the oral stage, stage, phallic stage, latency stage, and genital stage. Freud believed that the way individuals navigate these stages influences their personality and psychological well-being in adulthood.

Although Freud's stage theory has been critiqued and modified over time, his ideas regarding the importance of early childhood experiences and unconscious processes have had a profound impact on psychology and continue to shape our understanding of human development.

Compared with the beam, the large cube has the same volume but a smaller surface area.

It is defined as two-dimensional geometry in which the angle between the adjacent sides is 90 degrees. It is a type of quadrilateral. The area occupied by the rectangle in two-dimensional planner geometry.

The area of a rectangle can be calculated using the following formula:

Rectangle area = length x width

Given that, there are two sets of eight blocks, each with an edge measurement of 1 cm. Two blocks are placed on top of two other blocks to form a big cube. You assemble the second set into a 1-by-8-block straight beam.

Since the volume is the same.

The surface area of a cube,

=6a²

=6(2)²

=6×4

=24 cm²

The surface area of a beam,

Answer:

Travis

Step-by-step explanation:

Travis has previously shown himself to be faster than Wayne, thus he is most likely to still be faster.

If x is not an integer for any real number x and any integer m, then x + m x = m 1.

To prove this, we start by noting that ⌊x⌋ is the greatest integer less than or equal to x, while ⌊m-x⌋ is the greatest integer less than or equal to m-x. Adding these two expressions gives us ⌊x⌋ + ⌊m - x⌋ which is the greatest integer less than or equal to x plus the greatest integer less than or equal to m-x.

Since x is not an integer, we know that ⌊x⌋ < x < ⌊x⌋ + 1, and similarly, ⌊m - x⌋ < m - x < ⌊m - x⌋ + 1. Adding these inequalities gives us ⌊x⌋ + ⌊m - x⌋ < m - 1. On the other hand, if we subtract 1 from m, then we have m - 1 < m, which implies that ⌊m - x⌋ + ⌊x⌋ ≥ m - 1.

Combining these two inequalities gives us ⌊x⌋ + ⌊m - x⌋ = m - 1, as desired. Thus, we have proven the statement for any integer m and any real number x that is not an integer.

The polar equation is r=4+4cos(Θ)

When each point on a plane of a two-dimensional coordinate system is decided by a distance from a reference point and an angle is taken from a reference direction, it is known as the polar coordinate system. In the polar coordinate system, the origin is called a pole.

Given here, A microphone is placed in front of the choir to capture sound and we are required to find the polar equation representing the microphone the choir is using. The choir is using the cardinal plane equation which is generally given by r = r+rcos(θ)

No, the sample size of 48 observations is not adequate for the firm to be 99% confident that the standard time is within +5% of the true value.

To determine the proper sample size for the firm to be 99% confident that the standard time is within +5% of the true value, we need to calculate the required sample size using the formula for sample size determination.

The formula for sample size calculation is:

n = (Z * σ / E)^2

Where:

n = required sample size

Z = Z-score corresponding to the desired confidence level (99% confidence corresponds to Z = 2.58)

σ = standard deviation of the population

E = maximum allowable error (+5% of the true value, which corresponds to E = 0.05)

Given that the observed time has a standard deviation of 1.38 minutes, we can substitute the values into the formula and solve for the required sample size:

n = (2.58 * 1.38 / 0.05)^2

n = 194.09

Therefore, the proper number of observations should be 195 to achieve a 99% confidence level with a maximum allowable error of +5% of the true value. Since the current sample size is 48, it is not adequate to meet the desired level of confidence.

Measure of all angles must equal 180 degrees.

Therefore,
(4x+20) + (2x+34) + x = 180

6x + 54 + x = 180

7x + 54 = 180

7x = 126

x = 18

4(18)+20 = 92

Angle A = 92

2(18)+34 = 60
Angle C = 60 degrees

a. The missing probability value is 0.4.

b. E(X) = 1.4.

c. Var(X) = 0.56 and σx = 0.75.

d. E(Z) = 2.27, Var(Z) = 2.56, and σz = 1.60.

The given probability distribution of the random variable X shows the probabilities associated with each possible outcome. To find the missing probability value, we know that the sum of all probabilities must equal 1. Therefore, the missing probability can be calculated by subtracting the sum of the probabilities already given from 1. In this case, 0.1 + 0.2 + 0.3 = 0.6, so the missing probability value is 1 - 0.6 = 0.4.

To find the expected value or mean of X (E(X)), we multiply each value of X by its corresponding probability and then sum up the results. In this case, (0 * 0.1) + (1 * 0.2) + (2 * 0.3) + (3 * 0.4) = 0.4 + 0.2 + 0.6 + 1.2 = 1.4.

To calculate the variance (Var(X)) of X, we use the formula: Var(X) = Σ[(X - E(X))^2 * P(X)], where Σ denotes the sum over all values of X. The standard deviation (σx) is the square root of the variance. Using this formula, we find Var(X) = [(0 - 1.4)² * 0.1] + [(1 - 1.4)^2 * 0.2] + [(2 - 1.4)² * 0.3] + [(3 - 1.4)² * 0.4] = 0.56. Taking the square root, we get σx = √(0.56) ≈ 0.75.

Now, let's consider the new random variable Z = 1 + (2/3)X. To find E(Z), we substitute the values of X into the formula and calculate the expected value. E(Z) = 1 + (2/3)E(X) = 1 + (2/3) * 1.4 = 2.27.

To calculate Var(Z), we use the formula Var(Z) = (2/3)² * Var(X). Substituting the known values, Var(Z) = (2/3)² * 0.56 = 2.56.

Finally, the standard deviation of Z (σz) is the square root of Var(Z). Therefore, σz = √(2.56) = 1.60.

Answer:

x=8

Area= 60

Step-by-step explanation:

1. Use the Pythagorean Theorem: a^2+b^2=c^2.

c is always the longest side of the triangle, or the hypotenuse. The other two variables can be interchanged.

Let's plug the numbers into the equation now.

a^2+15^2=17^2

2. Square the two numbers you are given and isolate a.

15^2 (or 15 x 15) = 225

17^2 (or 17 x 17) = 289

So, the equation becomes: a^2 + 225 = 289

To get a by itself, subtract 225 from both sides and take the square root of the result

289-225= 64

√64 = 8

a= 8. x=8

3. Now that you have x, you can calculate the area if the triangle. The area formula for triangles is 1/2 base x height

Base is 15 and height is 8

15 x 8 = 120

120 x .5 = 60

Using Pythagoras theorem ,

Hypotenuse² = Base² + Height²

→ 17² = 15² + x²

→ 289 - 225 = x²

→ 64 = x²

→ x = √64

→ x = 8cm

Area = 1/2 × Base × height

=> 1/2 × 15 × 8

=> 2 × 15

=> Area = 30cm²

The vectors (1, -1), (1, 2), and (2, 1) are linearly dependent because they can be expressed as linear combinations of each other.

To show that the vectors are linearly dependent, we need to demonstrate that at least one of them can be expressed as a linear combination of the others. In this case, let's express the vector (2, 1) as a linear combination of the other two vectors.

We can write the vector (2, 1) as follows:

(2, 1) = a(1, -1) + b(1, 2)

Expanding the right side, we have:

(2, 1) = (a + b, -a + 2b)

By comparing the corresponding components, we get the following system of equations:

2 = a + b

1 = -a + 2b  

Solving this system of equations, we find that a = 1 and b = 1. Therefore, the vector (2, 1) can be expressed as a linear combination of the vectors (1, -1) and (1, 2), indicating that the three vectors are linearly dependent.

Since we have found a nontrivial solution to the equation, it confirms that the vectors (1, -1), (1, 2), and (2, 1) are linearly dependent.
