The number of respondents needed in a poll to adequately represent a larger population depends on several factors, such as the size of the population, the level of confidence desired, and the margin of error tolerated.

The general rule of thumb is that a sample size of at least 400 respondents is needed to provide a representative sample for a population of 100,000 or less. However, for larger populations, a sample size of at least 1,000 respondents may be required.

It is also important to note that a larger sample size does not always guarantee more accurate results. Other factors such as the sampling method, the wording of the questions, and the response rate can also impact the accuracy of poll results. Therefore, it is essential to carefully design and conduct polls to ensure their results are adequately representative of the larger population.

Step-by-step explanation:

When a double cone is sliced at the apex by a plane perpendicular to the base of the cone, the resulting conic section is a parabola.

Option B is the correct answer.

We have,

A parabola is a type of conic sect ion that can be defined as the locus of points equidistant from a fixed point (the focus) and a fixed line (the directrix).

In the case of slicing a double cone at the apex, the resulting conic section will have the characteristic shape of a parabola.

The slicing plane intersects both sides of the double cone, creating a curved shape that opens upward or downward, depending on the orientation of the cone.

The vertex of the parabola corresponds to the point of intersection of the slicing plane with the double cone.

Therefore,

When a double cone is sliced at the apex by a plane perpendicular to the base, a parabola is formed.

fv(40,20) ≈ (f(40.1,20) - f(40,20))/0.1 , ft(40,20) ≈ (f(40,20.05) - f(40,20))/0.05 are the required functional estimations of a given representations.

However, we can estimate the partial derivatives with respect to x (fv) and y (ft) at the point (40,20) using the definition of partial derivatives:

fv = ∂f/∂x ≈ (f(40+h,20) - f(40,20))/h

where h is a small increment in the x direction. Similarly,

ft = ∂f/∂y ≈ (f(40,20+k) - f(40,20))/k

where k is a small increment in the y direction.

To estimate fv(40,20) and ft(40,20), we need to choose small values of h and k and evaluate the function at the corresponding points. Let's say h = 0.1 and k = 0.05:

fv(40,20) ≈ (f(40.1,20) - f(40,20))/0.1

ft(40,20) ≈ (f(40,20.05) - f(40,20))/0.05

We can then use these estimates to approximate the value of f(40.1,20.05) using the first-order Taylor approximation:

f(40.1,20.05) ≈ f(40,20) + fv(40,20)0.1 + ft(40,20)0.05

Note that this is an approximation and may not be very accurate if the function is highly nonlinear or has discontinuities. However, it can give us a rough idea of the value of f(40,20) and how it changes with small variations in x and y.

Out of 41 observations, 60% were successes. H0: p = 0. The correct option is a.2.974.

Based on the given information, we know that out of 41 observations, 60% were successes. This means that there were 24.6 successes (60% of 41).

The null hypothesis (H0) states that the true proportion of successes (p) is 0.49.

To test this hypothesis, we can use a one-sample proportion z-test. The formula for this test statistic is:

z = (p^ - p) / sqrt(p * (1 - p) / n)

where p^ is the sample proportion (in this case, 0.6), p is the hypothesized proportion (0.49), and n is the sample size (41).

Plugging in these values, we get:

z = (0.6 - 0.49) / sqrt(0.49 * 0.51 / 41)
z = 2.974

This means that our test statistic is 2.974.

To find the p-value associated with this test statistic, we can use a standard normal distribution table or calculator. The p-value for a z-score of 2.974 is approximately 0.0029.

Since this p-value is less than the typical alpha level of 0.05, we would reject the null hypothesis and conclude that there is sufficient evidence to suggest that the true proportion of successes is not 0.49.

Therefore, our answer is (a) 2.974.

Answer:

The chemical element loses 4% of its weight everyday

Step-by-step explanation:

Here, we are interested in knowing the percentage weight loss of the chemical each day.

The key to answering this is looking at the expression inside the bracket.

We can express M(t) = 169•(0.96)^t as

M(t) = 169•(1-0.04)^t

So what this means is that we need to find the percentage value corresponding to 0.04 since it is a constant term here

Mathematically, 0.04 is same as 4/100, so we can clearly say that the constant percentage loss is 4%

Answer:

0.96

Step-by-step explanation:

The exponential function modeling the mass of the sample is of the form M(t)=A⋅Bt. Therefore, AAA determines the initial mass of the sample (when Clemence began studying it) and BBB determines the daily change in the mass of the sample.

The mass of the sample is multiplied by \it{0.96}0.960, point, 96 every day. Since 0.96<10.96<10, point, 96, is less than, 1, the mass of the sample shrinks by a factor of 0.960.960, point, 96 every day.

Every day, the mass of the sample shrinks by a factor of 0.960.960, point, 96.

Answer:

Choice D, 20 inches.

Step-by-step explanation:

The Pythaogorean theorem tells us that the hypotenuse of a triangle, c, can be found by taking: c = \(\sqrt{a^{2} +b^{2}}\). In this case, a = 3 and b = 4. So:

c = \(\sqrt{a^{2} + b^{2} }\)

c = \(\sqrt{3^{2} + 4^{2} }\)

c = \(\sqrt{9 + 16}\)

c = \(\sqrt{25}\)

c = 5

The requirement f(x1) * f(x2) < 0 for choosing initial guesses x1 and x2 with opposite signs ensures the validity and convergence of certain numerical root-finding methods such as the bisection method or the regula falsi method.

The statement you provided is true for certain numerical methods used to find roots of equations, such as the bisection method or the regula falsi method. These methods are iterative and require an initial interval or range where the root is expected to be found. To ensure convergence and a valid solution, it is necessary to choose initial guesses x1 and x2 such that the function f(x) evaluated at those points have opposite signs, i.e., f(x1) * f(x2) < 0.

The rationale behind this requirement is based on the Intermediate Value Theorem, which states that if a continuous function f(x) changes sign over an interval [x1, x2], then there exists at least one root within that interval. By ensuring that f(x1) and f(x2) have opposite signs, we guarantee the existence of a root within the interval [x1, x2].

The bisection method works by repeatedly bisecting the interval and selecting a new subinterval that contains the root. At each iteration, the method narrows down the interval by halving it, based on the sign change observed in the function evaluations.

Similarly, the regula falsi (or false position) method also operates by iteratively refining the interval based on the linear interpolation between the function values at the endpoints. The method adjusts the interval based on the sign change of the function, converging to the root.

Both methods rely on the property of opposite signs to guarantee convergence and avoid getting stuck in a non-converging or incorrect solution. If the initial guesses do not satisfy the condition f(x1) * f(x2) < 0, it is possible that the method fails to converge or converges to a different root or solution.

Integration testing is a form of testing that involves linking all of the individual components together and testing them as a group to uncover any defects between individual components.

Integration testing focuses on the interactions between different components of a system. It aims to identify any issues that may arise when the components are combined, such as communication errors, data discrepancies, or incorrect functional behavior. This type of testing is typically performed after unit testing, which tests individual components in isolation, and before system testing, which evaluates the entire system's functionality.

In summary, integration testing is a crucial step in the software testing process that ensures individual components work together seamlessly, helping to identify and resolve defects that may occur when these components are connected.

The matrix A^TA is symmetric positive definite if the columns of A are linearly independent.

A least-squares solution of Ax=b can be found by constructing the normal equations for x. The normal equations for x can be constructed by solving for Ax=b and setting the gradient equal to zero. The solution to this problem is the value of x that minimizes the squared distance between Ax and b.Let A be a matrix of size mxn and b a vector of size m. We are looking for a vector x that minimizes||Ax-b||^2. Note that: ||Ax-b||^2= (Ax-b)^T(Ax-b) = x^TA^TAx - 2b^TAx + b^Tb.

To minimize ||Ax-b||^2, we differentiate with respect to x and set the gradient equal to zero:

d/dx(||Ax-b||^2) = 2A^TAx - 2A^Tb = 0.

Rearranging this equation gives the normal equations:

A^TAx = A^Tb.

The matrix A^TA is symmetric positive definite if the columns of A are linearly independent.

An absolute value inequality is used to represent the situation given that

cases with values above and below the allowance are to be removed.

Reason:

The given parameter are;

Length of a case x ≤ 125 + 0.25

Length of a case x ≥ 125 - 0.25

Required:

Represent the cases that are to be removed using absolute inequality.

Solution:

The given inequalities sign can be rearranged to give the cases to be

removed as follows;

x ≥ 125 + 0.25

∴ x - 125 ≥ 0.25...(1)

x ≤ 125 - 0.25

x - 125 ≤ -0.25

Multiplying both sides by (-1) gives;

-1×(x - 125) ≥ (-1) × -0.25 = 0.25

-(x - 125) ≥ 0.25...(2)

Therefore;

The given that a case with difference (x - 125) ≥ 0.25 or when (x - 125) is

negative -(x - 125) ≥ 0.25 should be removed, using absolute inequality, we

have;

|x - 125| = (x - 125) when x > 125

|x - 125| = -(x - 125) when x < 125, and (x - 125) is negative

Which gives; A case with length |x - 125| ≥ 0.25 should be removed.

As per unitary method, Jake painted 6 more birdhouses red than yellow.

The Unitary Method is a strategy used to simplify mathematical calculations. The idea is to make the calculation easier by breaking down the numbers into smaller parts and then recombining them to find the final answer.

In this problem, we want to find out how many more birdhouses Jake painted red than yellow. To do this, we'll use the Unitary Method to subtract 7 from 13.

Starting with the larger number, we'll break down 13 into 10 and 3. We can then subtract 7 from 10 and find that there is a difference of 3.

This means that we have 3 left over from the larger number, which we can add to the smaller number (3) to find the final answer.

Therefore, the final answer is 3 + 3 = 6.

Answer:

No, the relation R^2 is not necessarily irreflexive.

Step-by-step explanation:

The relation R^2 represents the composition of the relation R with itself. In other words, it consists of pairs (a, c) such that there exists an intermediate element b for which (a, b) and (b, c) are both in R.

Even if the relation R is irreflexive (meaning there are no pairs (a, a) in R), the relation R^2 can still contain pairs (a, a) if there exists an intermediate element b such that (a, b) and (b, a) are both in R. In this case, (a, a) would be in R^2, violating the condition for irreflexivity.

Therefore, the relation R^2 can have reflexive elements even if the relation R is irreflexive.
