The pocket money that Sam had to start with is: £24

Let the amount of money he had at the beginning be x.

He spent 1/4 of the money on magazines. Thus:

Amount left = ³/₄x

He spent ²/₃ of what he had left on a present. Thus< he spent:

²/₃ * ³/₄x = ¹/₂x

Amount left = ³/₄x - ¹/₂x

He had £6 left. Thus:

The answer to this question is A. It is not reasonable to conclude that heart or respiratory diseases were the cause of approximately 29% of U.S. deaths in 2011 because there is a possibility of overlap.

This means that some people who died from heart disease may have also had respiratory diseases, and vice versa.

Therefore,

It is impossible to accurately determine the exact percentage of deaths caused by each individual disease.
It is important to note that the Centers for Disease Control lists the causes of death in the United States as the underlying cause, which is defined as the disease or injury that initiated the train of events leading directly to death.

However,

Many people who die from one disease may also have other underlying or contributing conditions.

This makes it difficult to determine the exact cause of death in some cases.
There could be potential overlap between heart and respiratory diseases, it is not reasonable to conclude that heart or respiratory diseases were the cause of exactly 29% of U.S. deaths in 2011.

In summary,

While heart and respiratory diseases were listed as the cause of a significant percentage of deaths in the United States in 2011, it is not accurate to conclude that they were the sole cause of approximately 29% of deaths due to the possibility of overlap.

It is important to consider all contributing factors when analyzing causes of death data.

Answer:

0.27

Step-by-step explanation:

Probability of picking a green is 0.27 (t nearest hundredth).

So for the population which is normally distributed using central limit theorem we get,

(A) For sample size n = 100, Pr(Ӯ <101) = 0.937.

(B) For random sample size n = 64, Pr(101< Ӯ <103) = 0.110.

(C) For sample size of n = 165, Pr(Ӯ >98) = 0.893

Given that the population mean (µY) = 100 and the population standard deviation σ2Y = 43.

For the sample size of n = 100.

Now the sample mean (Ӯ) = µY = 100 also.

The sample standard deviation (σ) = square root of (σ2Y/n) = square root of (43/100) = square root of (0.43) = 0.66 (Rounding off  to two decimal places).

Now, (101 - Ӯ)/σ = (101 - 100)/0.66 = 1.53

From the normal distribution table we can find P(Z < 1.53) = 0.937 (approximately).

Hence, Pr(Ӯ < 101) = 0.937 (approximately).

For random sample size n = 64.

sample standard deviation = (σ) = square root of (σ2Y/n) = square root of (43/64) = 0.82

Now,

(101 - 100)/0.82 = 1.22

(103 - 100)/0.82 = 3.66

From standard normal table we can get,

P(Z < 3.66) = 0.999

P(Z < 1.22) = 0.889

So, P(1.22 < z < 3.66) = 0.999 - 0.889 = 0.110

Hence, Pr(101< Ӯ <103) = 0.110.

Again for sample size of n = 165.

Sample standard deviation = square root of (σ2Y/n) = square root of (43/165) = 0.51

Now,

(98 - 100)/0.51 = - 1.24

From the standard normal distribution table we get, P(Z < - 1.24) = 0.107.

Now, Pr(Ӯ >98) = 1 - Pr(Ӯ < 98) = 1 - 0.107 = 0.893.

In robust optimization, a constraint that cannot be violated is known as a hard constraint.

Hard constraints must be satisfied by any feasible solution to the optimization problem, while soft constraints are allowed to be violated, but at a cost. Optional constraints are constraints that can be included or excluded from the problem formulation depending on the specific needs of the application.

On the other hand, optional constraints or soft constraints are those that can be violated to some extent without significantly affecting the overall objective of the optimization problem. Soft constraints are used to express preferences or goals that are desirable but not strictly necessary for the problem to be solved.

Frequency analysis is not useful for understanding the relationships among multiple variables.

Frequency analysis is a statistical technique that involves counting the frequency of each value or category within a dataset. It is useful for analyzing categorical and continuous variables and determining the degree of item nonresponse. It can also help in locating outliers, as the frequencies of unusual values can be easily identified.

However, frequency analysis alone cannot provide insights into the relationships among multiple variables, as it only focuses on the distribution of individual variables. To understand the relationships among variables, more advanced statistical techniques such as correlation analysis or regression analysis need to be employed.

To determine if the criteria for approximate normality is met, we need to check if both the sample size and sample proportion are large enough. The sample size is n = 11,954 which is greater than 10.

Additionally, the sample proportion of landing on its right side is p = 0.571 which is also greater than 10. Therefore, the criteria for approximate normality is met.

A 99% confidence interval would be wider than the 90% confidence interval. This is because a higher confidence level requires a larger range to ensure the true population proportion is captured within the interval with a higher degree of certainty.

The probability of drawing a white ball given that the ball is odd-numbered is 1/3.

We have,

There are a total of 15 balls in the bag, out of which 6 are white and odd-numbered.

To find the probability of drawing a white ball given that it is odd-numbered, we need to use conditional probability.

Let A be the event that the ball is white and B be the event that the ball is odd-numbered.

Then, we need to find P(A|B), the probability of A given B.

We know that P(B), the probability of drawing an odd-numbered ball, is:

P(B) = number of odd-numbered balls / total number of balls

= 9 / 15

= 3 / 5

We also know that P(A and B), the probability of drawing a white odd-numbered ball, is:

P(A and B) = number of white odd-numbered balls / total number of balls

= 3 / 15

= 1 / 5

Using the formula for conditional probability, we have:

P(A|B) = P(A and B) / P(B)

= (1/5) / (3/5)

= 1/3

Therefore,

The probability of drawing a white ball given that the ball is odd-numbered is 1/3.

The equivalent expression of 18 + 30 using distributive property is 6(3) + 6(5)

The distributive property states that for any numbers a, b, and c, a multiplied by (b+c) equals a multiplied by b plus a multiplied by c.

a(b + c) = a(b) + a(c)

The prime factor of 18 + 30 is written as;

18 + 30 = 2 x 3 x 3 + 2 x 3 x 5

18 + 30 = 2 x 3 x (3 + 5)

Simplifying the expression inside the parentheses gives:

2 x 3 x (3 + 5) = 6 (3 + 5)

applying distributive property we will have;

6 (3 + 5) = 6(3) + 6(5)

The composition of transformations that map ABCD to EHGF are:

Reflect over the x-axis, then translate (x + 3, y + 1)

In Mathematics and Geometry, a reflection over or across the x-axis is represented by this transformation rule (x, y) → (x, -y).

By applying a reflection over the x-axis to coordinate A of the image ABCD, we have the following:

(x, y)                               →              (x, -y)

Coordinate A = (-5, 2)   →  Coordinate A' = (-5, -(2)) = (-5, -2).

Furthermore, the transformation rule for the translation of a point by h units right and k units up is given by;

A' (x + h, y + k)         →  E(x', y')

A' (-5 + h, -2 + k)       →  E(-2, -1)

While there is a clear correlation between the number of miles driven and the amount of gasoline used (i.e., as the number of miles driven increases, the amount of gasoline used generally increases), this relationship is not necessarily causal.

There may be other factors at play, such as the efficiency of the vehicle, driving habits, and road conditions, that can affect the amount of gasoline used.

According to the given information, the sequence is divergent.

What is the convergence and divergence of the sequence?

Convergence: A sequence approaches a fixed number as the number of terms increases.

Divergence: A sequence does not approach a fixed number as the number of terms increases.

We can use the limit comparison test to determine the convergence/divergence of the sequence.

Let's consider the sequence bₙ = 1/n. We know that lim[n→∞] (1/n) = 0, and since sin(x) is a bounded function, we have |sin(11/n)| ≤ 1 for all n. Therefore,

0 ≤ |(−1)ⁿ sin(11/n)|/bₙ = |(−1)ⁿ sin(11/n)|n → 0

As a result, we can apply the limit comparison test with bₙ = 1/n. Since the series ∑ 1/n diverges (i.e., harmonic series), we conclude that the original series ∑ (−1)ⁿ sin(11/n) also diverges.

Therefore, the sequence is divergent.

A Pythagorean Triple is a set of three integers that are positive whole numbers, namely a, b, and c, such that a²+b²=c².

A Pythagorean triple consists of three positive integers a, b, and c, such that a2 + b2 = c2. Such a triple is commonly written (a, b, c), and a well-known example is (3, 4, 5). If (a, b, c) is a Pythagorean triple, then so is (ka, kb, kc) for any positive integer k. A primitive Pythagorean triple is one in which a, b and c are coprime (that is, they have no common divisor larger than 1). For example, (3, 4, 5) is a primitive Pythagorean triple whereas (6, 8, 10) is not.

Yes,

It is true that if A is invertible, then det(A⁽⁻¹⁾) = det(A).

The determinant of a matrix and its inverse are closely related.

The determinant of a matrix is nonzero, then the matrix is invertible, and its inverse has the same determinant as the original matrix.

The following properties of determinants:

det(AB) = det(A)det(B) for any square matrices A and B

If A is invertible, then det(A⁽⁻¹⁾) = 1/det(A)

Using these properties, we can write:

det(A⁽⁻¹⁾) = det(A⁽⁻¹⁾)det(AI) = det(A⁽⁻¹⁾A) = det(I) = 1

And:

det(A) = det(AA⁽⁻¹⁾) = det(A)det(A⁽⁻¹⁾)

Multiplying both sides by det(A⁽⁻¹⁾), we get:

det(A)det(A⁽⁻¹⁾) = det(A⁽⁻¹⁾)det(A⁽⁻¹⁾) = det(A⁽⁻¹⁾)det(A)

det(A⁽⁻¹⁾) = det(A).
