The statement is false. The correct answer is A. False. The sets do not have the same cardinality.

In this case, we are comparing two sets: (4, 7, 9) and (4, 4, 7, 9, 9). To determine if the statement is true or false, we need to check if both sets contain the same elements and if they have the same cardinality.

The first set (4, 7, 9) has a cardinality of 3, as it contains three unique elements. The second set (4, 4, 7, 9, 9) has a cardinality of 5, as it contains five elements (though some are duplicated). Since the two sets have different cardinalities, they cannot be equal, and the statement is false.

Answer B is incorrect because although some elements of the first set are duplicated in the second set, this is not the main reason the statement is false. The primary reason is the difference in cardinality.

Answer C is incorrect because the sets do not contain the same elements; the second set has duplicate elements.

Answer D is incorrect because the requirement for the sets to be equal is not based on duplication but rather on having the same elements and cardinality.

In conclusion, the statement is false because the two sets do not have the same cardinality, and thus, they cannot be considered equal. Therefore, the correct option is A.

The area that the Diamond Head Crater in Hawaii covers in square meters is approximately 78,201 square meters.

The diameter of the Diamond Head Crater = 3,486 feet.
So, the radius of the Diamond Head Crater = diameter/2= 3,486/2 = 1,743 feet
Therefore, the area of Diamond Head Crater = π r²
Where r = 1,743 feet and π (pi) = 3.14.
So, the area of Diamond Head Crater = 3.14 × (1743)² = 844,584 square feet.
To convert the square feet into square meters, we need to multiply the answer by a conversion factor i.e., 0.0929.
Conversion factor = 0.0929
Therefore, the area of Diamond Head Crater in squared meter is 844,584 × 0.0929 = 78,200.94 or 78,201 square meters.

Step-by-step explanation:

Geoff is feeling peckish, so he decides to pop into the shop and grab some snacks. He picks up a packet of crisps for 25p, a can of soup for 68p and a watermelon for £1.47. He wonders why the watermelon is so cheap, but he doesn't question it. He goes to the cashier and hands over a £5 note. The customer behind Geoff wonders "how much change does he get back?"

To figure this out, we need to add up the price of the snacks and take it away from the money Geoff gave. We can use a dot to show the pence as parts of a pound. For example, 25p = 0.25 pounds.

The price of the snacks is:

0.25 + 0.68 + 1.47 = 2.40 pounds

The money Geoff gave is:

5.00 pounds

The divergence theorem states that the surface integral of the divergence of a vector field over a closed surface is equal to the triple integral of the divergence of the vector field over the volume enclosed by the surface

we are given the vector field F = (11x, 2y, \(z^{2}\)) and the surface S defined by the equation \(x^2 + y^2 + z^2\)= 1, which represents a unit sphere.

To evaluate the surface integral ∬S F · ds using the divergence theorem, we first need to calculate the divergence of the vector field F. The divergence of F, denoted as ∇ · F, is given by the sum of the partial derivatives of the components of F with respect to their corresponding variables. Therefore, ∇ · F = ∂(11x)/∂x + ∂(2y)/∂y + ∂(z^2)/∂z = 11 + 2 + 2z.

Applying the divergence theorem, the surface integral ∬S F · ds is equal to the triple integral ∭V (∇ · F) dV, where V represents the volume enclosed by the surface S.

Since the surface S is a unit sphere centered at the origin, the triple integral ∭V (∇ · F) dV can be evaluated by integrating over the volume of the sphere.

To estimate the length of the lake, we can use the law of cosines. The law of cosines states that in a triangle, the square of any side is equal to the sum of the squares of the other two sides minus twice the product of those sides and the cosine of the angle between them.In this case, the triangle is formed by Caleb's two paths and the line connecting the start and end of his walk. The side opposite the angle of 120° is the length of the lake. The other two sides are 95m and 87m.We can use the law of cosines to find the length of the lake as follows:

(length of lake)^2 = 95^2 + 87^2 - 2 * 95 * 87 * cos(120°)

cos(120°) = -0.5

(length of lake)^2 = 95^2 + 87^2 + 95 * 87 * 0.5

(length of lake)^2 = 23790

length of lake = 154.2m

Therefore, the lake is approximately 154.2 metres.

The product of a scalar (number) with a lower triangular matrix is a lower triangular matrix.

In linear algebra, matrices are crucial, and one of the critical matrix types is the lower triangular matrix. A lower triangular matrix is a matrix that has elements on the diagonal and below the diagonal, while the upper triangle of the matrix has elements that are zero. Scalar multiplication is one of the fundamental operations in linear algebra, where a scalar or a number multiplies a matrix to produce a new matrix. The product of a scalar or number with a lower triangular matrix is a lower triangular matrix. The scalar multiplication distributes the scalar to all the elements of the matrix, and if the matrix is a lower triangular matrix, then its elements below the diagonal are already zero, which means that the scalar multiplication will not affect them. The scalar multiplication will only affect the elements on the diagonal of the matrix and still preserve the lower triangular structure of the matrix. To better understand this, let us consider a 3x3 lower triangular matrix L, given by:0 0 00 2 00 3 1. Let us multiply the matrix L by a scalar k; we have: kL = k[0 0 00 2 00 3 1] = [k*0 k*0 k*0k*0 k*2 k*0k*0 k*3 k*1] = [0 0 00 2k 00 3k k]The result is still a lower triangular matrix, and the scalar multiplication of k did not affect the lower triangular structure of the matrix.

In summary, when we multiply a lower triangular matrix by a scalar, we will still have a lower triangular matrix. The scalar multiplication does not affect the lower triangle structure of the matrix but only affects the elements on the diagonal. This property is crucial when we want to perform scalar multiplication of matrices, especially lower triangular matrices.

With continuity correction: 0.0087(a) To compute the exact probability that X is less than 16, we can use the Poisson probability formula:

P(X < 16) = Σ [e^(-λ) * (λ^k) / k!], where k ranges from 0 to 15.

Using λ = 24, we have:

P(X < 16) = Σ [e^(-24) * (24^k) / k!], where k ranges from 0 to 15.

Calculating this sum using a calculator or software, we find:

P(X < 16) ≈ 0.979

Therefore, the exact probability that X is less than 16 is approximately 0.979.

(b) Using the normal approximation, we can approximate the probability that X is less than 16.

Without continuity correction:

To use the normal approximation without continuity correction, we can approximate the Poisson distribution with a normal distribution using the mean (λ) and standard deviation (√λ) of the Poisson distribution.

Mean (μ) = λ = 24

Standard Deviation (σ) = √λ = √24

Now, we can standardize the value 16 using the formula z = (x - μ) / σ:

z = (16 - 24) / √24 ≈ -2.309

Using the standard normal distribution table or a calculator, we find that the cumulative probability for z = -2.309 is approximately 0.0106.

Without continuity correction: 0.0106

With continuity correction:

To apply the continuity correction, we adjust the boundaries by 0.5:

z = (16 - 0.5 - 24) / √24 ≈ -2.386

Using the standard normal distribution table or a calculator, we find that the cumulative probability for z = -2.386 is approximately 0.0087.

With continuity correction: 0.0087

(c) To approximate the probability that X is greater than or equal to 32:

Without continuity correction:

We can use the normal approximation and calculate the z-score for 32:

z = (32 - 24) / √24 ≈ 2.309

Using the standard normal distribution table or a calculator, we find that the cumulative probability for z = 2.309 (to the left of the z-score) is approximately 0.9894. Since we want the probability of X being greater than or equal to 32, we subtract this value from 1:

1 - 0.9894 = 0.0106

Without continuity correction: 0.0106

With continuity correction:

Using the continuity correction, we adjust the boundaries:

z = (32 + 0.5 - 24) / √24 ≈ 2.386

Using the standard normal distribution table or a calculator, we find that the cumulative probability for z = 2.386 (to the left of the z-score) is approximately 0.9913. Subtracting this value from 1 gives us:

1 - 0.9913 = 0.0087

The robot moves in the positive direction along a straight line so that after t minutes its distance is s=6t^4 feet from the origin. (a) Find the average velocity of the robot over intervals 2, 4. We have the following data: Initial time, t₁ = 2 min.

Final time, t₂ = 4 min.The distance from the origin is given by s = 6t^4Therefore, s₁ = s(2) = 6(2^4) = 6(16) = 96 feet s₂ = s(4) = 6(4^4) = 6(256) = 1536 feet

We can find the average velocity of the robot over the interval 2, 4 as follows: Average velocity = (s₂ - s₁) / (t₂ - t₁)Average velocity = (1536 - 96) / (4 - 2)Average velocity = 1440 / 2Average velocity = 720 feet per minute(b) Find the instantaneous velocity at t=2.To find the instantaneous velocity at t = 2 min, we need to take the derivative of the distance function with respect to time. We have the distance function as:s = 6t^4 Taking derivative of s with respect to t gives the velocity function:v = ds / dt Therefore,v = 24t³At t = 2, the instantaneous velocity is:v(2) = 24(2)³v(2) = 24(8)v(2) = 192 feet per minute Therefore, the instantaneous velocity at t = 2 min is 192 feet per minute.

A. Disproportionate stratified sampling involves dividing the population into different groups (strata) based on certain characteristics and then intentionally selecting a different proportion of individuals from each group. In this case, the researchers are dividing the population based on sexual orientation (straight and LGBTQ+) and selecting an equal proportion from each group.

B. Availability sampling (also known as convenience sampling) refers to selecting individuals who are readily available or convenient for the researcher. This type of sampling does not guarantee representative or unbiased results and may introduce bias into the study.

C. Snowball sampling involves starting with a small number of participants who meet certain criteria and then asking them to refer other potential participants who also meet the criteria. This sampling method is often used when the target population is difficult to reach or identify, such as in hidden or marginalized communities.

D. Simple random sampling involves randomly selecting individuals from the population without any specific stratification or deliberate imbalance. Each individual in the population has an equal chance of being selected.

The standard deviations that would meet a 5-sigma capability for Cpk are  0.005, 0.015, and 0.025. (Options A, B and C).

To determine which standard deviations would meet a 5-sigma capability for Cpk, we need to use the following formula:

Cpk = minimum((USL - mean) / 3sigma, (mean - LSL) / 3sigma)

where USL is the upper specification limit, LSL is the lower specification limit, mean is the process mean, and sigma is the process standard deviation.

For a 5-sigma capability, we want Cpk to be at least 2.0, so we can set up the following inequality:

2.0 <= minimum((USL - mean) / 3sigma, (mean - LSL) / 3sigma)

Assuming the process mean remains unchanged, and the specification limits are at ±3 sigma from the mean (which is a common assumption), we can simplify the inequality to:

2.0 <= 1/3sigma

which can be rearranged as:

sigma <= 1/6

Therefore, the standard deviation should be less than or equal to 0.1667 to achieve a 5-sigma capability.

Now we can check which of the given standard deviations meet this criterion:

a. 0.005: Yes, this is less than 0.1667.

b. 0.015: Yes, this is less than 0.1667.
