B x A = -10k. This shows that the cross product of two vectors is not commutative because A x B ≠ B x A. In this example, reversing the order of the input vectors results in vectors that have the same magnitude but opposite directions.

The cross product of vectors is a binary operation that takes two vectors and produces a new vector that is perpendicular to the two input vectors. However, it is important to note that the cross product of two vectors is not commutative.

This implies that reversing the order of the vectors being crossed results in a different vector. An example to show that vectors are not commutative under the cross product operation is given below.Suppose we have two vectors, A and B. Let A = 3i + 2j and B = i + 4j, where i and j are the unit vectors along the x and y axes, respectively.

To compute the cross product of A and B, we can use the determinant formula: A x B = |i j k|3 2 0 1 4 0| = (0-0)i - (0-0)j + (3(4)-2(1))k = 10k

Thus, A x B = 10k. Now, to compute the cross product of B and A, we reverse the order of the input vectors and use the same formula: B x A = |i j k|1 4 0 3 2 0| = (0-0)i - (0-0)j + (1(2)-4(3))k = -10k

Step-by-step explanation:

How to explain the word problem It should be noted that to determine if Jenna's score of 80 on the retake is an improvement, we need to compare it to the average improvement of the class. From the information given, we know that the class average improved by 10 points, from 50 to 60. Jenna's original score was 65, which was 15 points above the original class average of 50. If Jenna's score had improved by the same amount as the class average, her retake score would be 75 (65 + 10). However, Jenna's actual retake score was 80, which is 5 points higher than what she would have scored if she had improved by the same amount as the rest of the class. Therefore, even though Jenna's score increased from 65 to 80, it is not as much of an improvement as the average improvement of the class. To show the same improvement as her classmates, Jenna would need to score 75 on the retake.

we need to use the central limit theorem, which states that the distribution of the sample means of a large sample (n > 30) taken from a normally distributed population will also be normally distributed, with a mean equal to the population mean and a standard deviation equal to the population standard deviation divided by the square root of the sample size.

we have a normally distributed population with a mean of 60 and a standard deviation of 10. We want to find the probability that the mean of a sample of 25 elements taken from this population will be smaller than 56. Using the central limit theorem, we can calculate the standard error of the mean as 10 / sqrt(25) = 2. Therefore, the z-score corresponding to a sample mean of 56 is (56 - 60) / 2 = -2. Therefore, the probability that the mean of a sample of 25 elements taken from this population will be smaller than 56 is 0.0228 or approximately 2.28%. A distributed population refers to a set of data points that follow a specific pattern. In this case, the population is normally distributed with a mean of 60 and a standard deviation of 10. To find the probability that the mean of a sample of 25 elements is smaller than 56, we'll use the concept of standard deviation.
Step 1: Calculate the standard error (SE) using the formula SE = (Standard Deviation) / √(Sample Size), which is SE = 10 / √25 = 2.
Step 2: Compute the z-score using the formula z = (Sample Mean - Population Mean) / SE, which is z = (56 - 60) / 2 = -2.
Step 3: Refer to a standard normal distribution table or use a calculator to find the probability corresponding to the z-score. In this case, the probability is approximately 0.0228 or 2.28%.

a. Own Price Elasticity of Demand = (-30) / (0) = undefined. Since the own price elasticity of demand is undefined, we cannot determine if the demand is elastic, inelastic, or unitary elastic based on this information.

b. Cross-Price Elasticity of Demand = (12/7) / 0 = undefined. Since the cross-price elasticity of demand is undefined, we cannot determine if goods X and Y are substitutes or complements based on this information.

c. Income Elasticity of Demand = (-2860.71) / (0) = undefined. Since the income elasticity of demand is undefined, we cannot determine if good X is a normal or inferior good based on this information.

d. We cannot calculate the own advertising elasticity of demand with the provided data.

a. To determine the own price elasticity of demand, we need to use the formula:

Own Price Elasticity of Demand = (% Change in Quantity Demanded) / (% Change in Price)

Given the demand equation OX​d​ = 7−15PX​+2Py​+0.5M+A, we can calculate the derivative of demand with respect to price:

d(OX​d​) / d(PX​) = -15

Now, let's plug in the values:

% Change in Quantity Demanded = (d(OX​d​) / d(PX​)) * (PX​ / OX​d​) = (-15) * (15 / 7) = -30

% Change in Price = (ΔPX​ / PX​) = (15 - 15) / 15 = 0

b. To determine the cross-price elasticity of demand between goods X and Y, we use the formula:

Cross-Price Elasticity of Demand = (% Change in Quantity Demanded of Good X) / (% Change in Price of Good Y)

Using the same demand equation, we calculate the derivative of demand with respect to the price of good Y:

d(OX​d​) / d(Py​) = 2

Now, let's plug in the values:

% Change in Quantity Demanded of Good X = (d(OX​d​) / d(Py​)) * (Py​ / OX​d​) = (2) * (6 / 7) = 12/7

% Change in Price of Good Y = (ΔPy​ / Py​) = (6 - 6) / 6 = 0

c. To determine the income elasticity of demand, we use the formula:

Income Elasticity of Demand = (% Change in Quantity Demanded) / (% Change in Income)

Using the same demand equation, we calculate the derivative of demand with respect to income:

d(OX​d​) / d(M) = 0.5

Now, let's plug in the values:

% Change in Quantity Demanded = (d(OX​d​) / d(M)) * (M / OX​d​) = (0.5) * (-40000 / 7) = -2860.71

% Change in Income = (ΔM / M) = (-40000 - (-40000)) / (-40000) = 0

The formula for the test statistic Z depends on the specific hypothesis test being conducted. However,  the test statistic Z can be computed as:

Z = (x - μ) / (σ / √n)

The formula for the test statistic Z is:

where:

x is the sample mean

μ is the population mean (under the null hypothesis)

σ is the population standard deviation (under the null hypothesis)

n is the sample size

This formula is used for a z-test, which is a statistical test that assumes that the population is normally distributed and uses the standard normal distribution to calculate the p-value.

In some cases, the population standard deviation is unknown, and so the sample standard deviation (s) is used as an estimate. In these cases, the formula for the test statistic Z is:

The expression n^3 - n is divisible by 6 for any nonnegative integer n.

To prove that 6 divides n^3 - n, we can factorize the expression.

n^3 - n = n(n^2 - 1)

Now, we can further factorize n^2 - 1 as (n + 1)(n - 1).

Therefore, n^3 - n can be written as n(n + 1)(n - 1).

From this expression, we can see that for any nonnegative integer n, at least one of n, n + 1, or n - 1 is divisible by 2, and at least one of them is divisible by 3.

Since 2 and 3 are both prime factors of 6, it follows that 6 divides n^3 - n for any nonnegative integer n.

To determine the probability that the total weight of the passengers on a given flight exceeds 4000 pounds, we can use the concept of the normal distribution. Given the average weight of passengers, the standard deviation, and the number of passengers on the flight, we can calculate the probability using the properties of the normal distribution.

Given:
Average weight of passengers: 190 pounds
Standard deviation: 35 pounds
Number of passengers: 20
To find the probability that the total weight of the passengers on the flight exceeds 4000 pounds, we need to calculate the z-score for the given weight threshold:
Z = (4000 - (190 * 20)) / (35 * √(20))
Next, we use a standard normal distribution table or calculator to find the probability associated with the calculated z-score:
P(Z > Z)
This probability represents the proportion of the population that exceeds the given weight threshold. It indicates the likelihood that the total weight of the passengers on the flight will exceed 4000 pounds.
By applying these calculations, we can determine the probability that the total weight of the passengers on the flight exceeds the specified threshold.

Use the Law of Sines to solve the triangle. (Round your answers to two decimal places.)

A = 73°, a = 39, b = 24

Answer:

The answer is option D.

Equation of a line is y = mx + c

m = slope

c = intercept on y axis

y-4= -2/3 (x-6)

y = -2/3x + 4 + 4

y = -2/3x + 8

From the above equation

m= -2/3

Since the lines are perpendicular the slope of the line is the negative inverse of the original line.

so m = 3/2

Equation of the line using point (-2 , -2) is

y + 2 = 3/2(x+2)

y = 3/2x + 3 - 2

y = 3/2x + 1

That's the last option

Therefore, we have:

P(z ≥ c) = 0.55

P(z ≤ c) = 1 - P(z ≥ c) = 1 - 0.55 = 0.45

Using the standard normal distribution table, we find that the z-score corresponding to a left-tailed area of 0.45 is approximately -0.126.
