Answer:

DB = 10

m∡C = 106°

Step-by-step explanation:

DE = EB

20x - 8 = 16x + 12

4x = 20

x = 5

DB = 5 doubled, or 10

m∡A + m∡D = 180

3y + 7 + 2y + 8 = 180

5y + 15 = 180

5y = 165

y = 33

m∡A = m∡C

m∡A = 3(33)+7 = 106°

m∡C = 106° also

The theoretical mean for a draw from a Poisson distribution with parameter λ is equal to λ itself. In this case, λ = 37, so the theoretical mean is also 37.

Explanation:

The Poisson distribution is commonly used to model the number of events occurring within a fixed interval of time or space, when these events occur with a known average rate λ. The probability mass function of the Poisson distribution is given by P(X=k) = (e^(-λ) * λ^k) / k!, where X represents the random variable representing the number of events and k is the observed value.

The Central Limit Theorem states that when independent random variables are added, their sum tends toward a normal distribution, regardless of the shape of the original distribution. For a Poisson distribution, as the parameter λ increases, the distribution becomes more symmetric and bell-shaped, resembling a normal distribution.

Since the mean of a Poisson distribution is equal to its parameter λ, the theoretical mean for a draw from a Poisson distribution with parameter 1 = 37 is 37. This means that, on average, 37 events are expected to occur within the given interval.

[tex]6x^{3} -25x^{2} +6x+5[/tex]

Step-by-step explanation:

The comparison of systolic blood pressure in the sitting and standing positions is an example of testing the difference between matched pairs from two dependent populations.

The scenario described involves measuring the systolic blood pressure of the same set of patients in two different positions (sitting and standing). This creates a dependency between the measurements because each patient serves as their own control. In this case, the appropriate statistical test would be a paired t-test or a related test for dependent samples.

Two means from independent populations: This option would be suitable if the measurements were taken from two different groups of patients who were independent of each other, but in this case, the same individuals were measured in both positions. Two population proportions: This option would be applicable if the data involved proportions or categorical variables, rather than continuous measurements like blood pressure.

Matched pairs from two dependent populations: This option accurately represents the scenario described, as the measurements were taken from the same individuals in both positions, making them dependent on each other.

The explicit formula for the sequence [tex]\(a_n\)[/tex] is:

[tex]\(a_n = \begin{cases} 4n + 3 & \text{if } n \text{ is even} \\ 4n - 2 & \text{if } n \text{ is odd} \end{cases}\)[/tex]

To find an explicit formula for the sequence [tex]\(a_n\)[/tex] that satisfies the recurrence relation [tex]\(a_n = 2n-1 + 2a_{n-2}\)[/tex] with initial conditions [tex]\(a_1 = 2\)[/tex] and [tex]\(a_2 = 7\)[/tex], we can proceed as follows:

First, let's examine the first few terms of the sequence:

[tex]\(a_1 = 2\)\\\(a_2 = 7\)\\\(a_3 = 2(3) - 1 + 2a_1 = 5 + 2(2) = 9\)\\\(a_4 = 2(4) - 1 + 2a_2 = 8 + 2(7) = 22\)\\\(a_5 = 2(5) - 1 + 2a_3 = 9 + 2(9) = 27\)\\[/tex]

We can observe that the even-indexed terms [tex]\(a_2, a_4, a_6, \ldots\)[/tex] are increasing by a factor of 2, while the odd-indexed terms [tex]\(a_1, a_3, a_5, \ldots\)[/tex] are increasing by a factor of 3. This pattern suggests that we can split the sequence into two separate sequences:

For even-indexed terms:

[tex]\(b_n = a_{2n}\)[/tex]

For odd-indexed terms:

[tex]\(c_n = a_{2n-1}\)[/tex]

Let's find explicit formulas for both [tex](\(b_n\))[/tex] and [tex](\(c_n\))[/tex]:

1. Even-indexed terms [tex](\(b_n\))[/tex]:

The recurrence relation becomes:

[tex]\(b_n = 2(2n) - 1 + 2b_{n-1}\)[/tex]

To simplify the formula, let's rewrite [tex]\(b_n\)[/tex] as [tex]\(b_{n+1}\)[/tex] (i.e., shifting the index by 1):

[tex]\(b_{n+1} = 2(2n + 2) - 1 + 2b_{n}\)[/tex]

Subtracting the two equations, we get:

[tex]\(b_{n+1} - b_n = 4\)[/tex]

This is a simple arithmetic progression with a common difference of 4. To find an explicit formula for [tex]\(b_n\)[/tex], we can use the formula for the nth term of an arithmetic progression:

[tex]\(b_n = b_1 + (n - 1) \cdot \text{{common difference}}\)[/tex]

Substituting [tex]\(b_1 = a_2 = 7\)[/tex] and the common difference of 4, we have:

[tex]\(b_n = 7 + (n - 1) \cdot 4 = 4n + 3\)[/tex]

2. Odd-indexed terms [tex](\(c_n\))[/tex]:

The recurrence relation becomes:

[tex]\(c_n = 2(2n-1) - 1 + 2c_{n-1}\)[/tex]

Similar to before, let's rewrite [tex]\(c_n\)[/tex] as [tex]\(c_{n+1}\)[/tex]:

[tex]\(c_{n+1} = 2(2n + 1) - 1 + 2c_{n}\)[/tex]

Subtracting the two equations, we get:

[tex]\(c_{n+1} - c_n = 4\)[/tex]

Again, this is an arithmetic progression with a common difference of 4. Applying the formula for the nth term of an arithmetic progression:

[tex]\(c_n = c_1 + (n - 1) \cdot \text{{common difference}}\)[/tex]

Substituting [tex]\(c_1 = a_1 = 2\)[/tex] and the common difference of 4, we have:

[tex]\(c_n = 2 + (n - 1) \cdot 4 = 4n-2[/tex]

1) [tex]\cdot 4 = 4n - 2\)[/tex]

Now that we have explicit formulas for both [tex]\(b_n\)[/tex] and [tex]\(c_n\)[/tex], we can combine them to obtain the explicit formula for the original sequence [tex]\(a_n\)[/tex]:

For even-indexed terms, [tex]\(a_{2n} = b_n = 4n + 3\)[/tex]

For odd-indexed terms, [tex]\(a_{2n-1} = c_n = 4n - 2\)[/tex]

Therefore, the explicit formula for the sequence [tex]\(a_n\)[/tex] is:

[tex]\(a_n = \begin{cases} 4n + 3 & \text{if } n \text{ is even} \\ 4n - 2 & \text{if } n \text{ is odd} \end{cases}\)[/tex]

The strophoid is a curve represented by the polar equation r = sec(θ) − 2cos(θ), where -2 < θ < 2. In Cartesian coordinates, the strophoid equation can be written as (x^2 + y^2)^2 = 4y^2(x + 2).

The strophoid has a unique shape characterized by its looped structure.

The strophoid is symmetric with respect to the y-axis, as changing θ to -θ gives the same value of r. It has two branches that intersect at the origin (0, 0). As θ increases from -2 to 2, the curve starts from the rightmost point of the loop, extends to the left, and then returns back to the rightmost point.

The loop of the strophoid is created by the interplay of the secant function, which stretches the curve away from the origin, and the cosine function, which pulls it towards the origin. The strophoid exhibits interesting geometric properties and is often used in mathematical modeling and visualization.
