How much a statistic varies from one sample to another is known as the sampling variability of a statistic.

Testing variability arises due to the reality that exceptional samples of the same size can produce special values of a statistic, although the samples are described from the same populace. the quantum of slice variability depends on the scale of the sample, the variety of the populace, and the unique statistic being calculated.

The end of statistical conclusion is to apply the data attained from a sample to make consequences about the population, while counting for the slice variability of the statistic. ways similar as thesis checking out and tone belief intervals do not forget the sampling variability of a statistic to make redundant accurate consequences about the populace.

To indicate the direction in which the curve is traced as the parameter increases, we can draw an arrow that points from lower left to upper right, since the curve moves from the point (1, 1) at t = 0 to the right and upward as t increases.

To eliminate the parameter, we can use the fact that x = e^t and y = e^(-3t) to solve for t in terms of x and y. Taking the natural logarithm of both sides of x = e^t, we get ln(x) = t. Similarly, taking the natural logarithm of both sides of y = e^(-3t), we get ln(y) = -3t, or t = (-1/3)ln(y). Substituting this expression for t into the equation we found for ln(x), we get ln(x) = (-1/3)ln(y), which simplifies to ln(x^3) = ln(y^(-1)), or x^3 = 1/y. This is the Cartesian equation of the curve.

To sketch the curve, we can start by noting that both x and y are positive for all values of t, since e^t and e^(-3t) are always positive. As t increases, x and y both increase, but y increases much more slowly than x since e^(-3t) decreases rapidly as t increases. This means that the curve starts out very steep (since the slope of the tangent line at t = 0 is dx/dt = 1 and dy/dt = -3), but becomes flatter and flatter as t increases. The curve approaches the x-axis as t approaches infinity, but never touches it.

A stochastic process X(t) is called a martingale if the expected value of X(t) given all information available up to and including time s is equal to the value of X(s).

Thus, to show that the process X(t):=e^(t/2)cos(W(t)), 0 ≤ t ≤ T is a martingale w.r.t. any filtration for Brownian motion, we need to prove that E(X(t)|F_s) = X(s), where F_s is the sigma-algebra of all events up to time s.

As X(t) is of the form e^(t/2)cos(W(t)), we can use Itô's lemma to obtain the differential form:dX = e^(t/2)cos(W(t))dW - 1/2 e^(t/2)sin(W(t))dt

Taking the expectation on both sides of this equation gives:E(dX) = E(e^(t/2)cos(W(t))dW) - 1/2 E(e^(t/2)sin(W(t))dt)Now, as E(dW) = 0 and E(dW^2) = dt, the first term of the right-hand side vanishes.

For the second term, we can use the fact that sin(W(t)) is independent of F_s and therefore can be taken outside the conditional expectation:

E(dX) = - 1/2 E(e^(t/2)sin(W(t)))dt = 0Since dX is zero-mean, it follows that X(t) is a martingale w.r.t. any filtration for Brownian motion.

Now, let's represent X(t) as an Itô process on the interval [0,T]. Applying Itô's lemma to X(t) gives:

dX = e^(t/2)cos(W(t))dW - 1/2 e^(t/2)sin(W(t))dt= dM + 1/2 e^(t/2)sin(W(t))dt

where M is a martingale with M(0) = 0.

Thus, X(t) can be represented as an Itô process on [0,T] of the form:

X(t) = M(t) + ∫₀ᵗ 1/2 e^(s/2)sin(W(s))ds

Hence, we have shown that X(t) is a martingale w.r.t. any filtration for Brownian motion and represented it as an Itô process on any time interval [0,T], T > 0.

The line plot shows that Dorothy has two baskets of 5 apples each, one basket of 3 apples, one basket of 2 apples, and one basket of 1 apple. The total weight of Dorothy's apples is 16.

Dorothy has a basket of apples. She decided to weigh the apples and make a table to show how many apples she has of each weight. She created a line plot to show the data. From the line plot, it can be seen that Dorothy has two baskets of 5 apples each, one basket of 3 apples, one basket of 2 apples, and one basket of 1 apple. The total weight of Dorothy's apples is 16. This means that Dorothy has a total of 16 apples. Since Dorothy has grouped apples that have the same weight in a basket, it can be seen that each basket has a different weight. The two baskets of 5 apples each have a total weight of 10, the basket of 3 apples has a total weight of 3, the basket of 2 apples has a total weight of 2, and the basket of 1 apple has a total weight of 1.

The angle that is equal to two-seventh of its supplement is 40°.

Two angles A and B are supplementary to each other, if and only if m ∠A + m ∠B = 180°.

In the question, we are asked to find the angle that is two-seventh of its supplement.

We assume the angle to be x°.

The supplement of this angle will be valued as (180 - x)°.

Now, we are told that the required angle is two-seventh of its supplement, that is, x = (2/7)(180 - x), which makes an equation in the variable x.

We can solve this equation as follows:

x = (2/7)(180 - x),

or, 7x = 360 - 2x,

or, 7x + 2x = 360,

or, 9x = 360,

or, x = 40.

When the depth of the water is 10 m, the radius is increasing at a rate of 80 m/s, and when the depth is 15 m, the water level is increasing at the same rate of 80 m/s.

To solve the problem, we'll use related rates, which involves finding the rate at which one quantity changes with respect to another quantity. Let's address each part of the problem separately:

(a) To find the rate at which the radius of the surface of the water is increasing when the depth of the water is 10 m, we'll need to find the relationship between the radius and the depth.

Using the given information, we know that the vertical angle of the cone is 60°. This means the half-angle at the apex of the cone is 30°.

Now, let's denote the radius of the surface of the water as 'r' and the depth of the water as 'd'. We want to find dr/dt, the rate at which the radius is changing with respect to time.

By considering the similar triangles formed by the height of the cup, the radius, and the depth of the water, we can establish the relationship:

r/d = tan(30°)

To find dr/dt, we differentiate both sides of the equation with respect to time:

\((1/d) * (dr/dt) = sec^2(30°) * (d/dt)\)

Since the rate at which the water is being poured is given as 60 m^3 per second, d/dt = \(60 m^3/s.\)

Plugging in the values, we have:

\((1/10) * (dr/dt) = sec^2(30°) * 60\)

Simplifying, we find:

\((dr/dt) = (600 * sec^2(30°))/10\)

sec(30°) = 1 / cos(30°) = 1 / (√3/2) = 2/√3 = (2√3) / 3

Now, let's substitute this value into the equation and simplify further:

(1/10) * (dr/dt) = (sec^2(30°)) * 60

(1/10) * (dr/dt) = ((2√3) / 3)^2 * 60

(1/10) * (dr/dt) = (4/3) * 60

(1/10) * (dr/dt) = 80

Finally, we can solve for (dr/dt) by multiplying both sides of the equation by 10:

(dr/dt) = 80 * 10

(dr/dt) = 800

Finally, we substitute the value of \(sec^2(30°) = 4/3:\)

\((dr/dt) = (800/10) = 80 m/s\)

Therefore, when the depth of the water is 10 m, the radius of the surface of the water is increasing at a rate of 80 m/s.

(b) To find the rate at which the water level is increasing when the depth of the water is 15 m, we need to determine dh/dt, the rate at which the height is changing with respect to time.

Using the relationship between the height and the depth of the water in the cone, we have:

h = d * tan(30°)

Differentiating both sides of the equation with respect to time, we get:

Let's denote the derivative with respect to time as d/dt. The chain rule states that if y = f(u) and u = g(t), then dy/dt = dy/du * du/dt.

In this case, we have h = d * tan(30°), where d is a constant. Differentiating both sides with respect to time, we get:

d/dt (h) = d/dt (d * tan(30°))

The derivative of h with respect to time (dh/dt) is what we're looking for. The derivative of d (a constant) with respect to time is zero since it is not changing.

To differentiate tan(30°), we need to use the trigonometric identity:

d/dx (tan(x)) = sec^2(x)

Therefore:

d/dt (tan(30°)) = sec^2(30°)

Substituting these results back into the original equation, we have:

dh/dt = 0 + d/dt (d * tan(30°))

dh/dt = 0 + d * sec^2(30°)

Since \(sec^2(30°)\) is a constant, we can simplify further:

dh/dt = d * \(sec^2(30°)\)

dh/dt =\(sec^2(30°) * (d/dt)\)

Again, substituting d/dt =\(60 m^3/s\), we have:

dh/dt =\(sec^2(30°) * 60\)

Using the value of sec^2(30°) = 4/3:

dh/dt = (4/3) * 60

Simplifying, we find:

dh/dt = 80 m/s

Therefore, when the depth of the water is 15 m, the water level is increasing at a rate of 80 m/s.

The predetermined overhead rate is the estimated manufacturing overhead cost per unit of a specific allocation base.

In the options, there are four different rates:

1. $10.00 / MH (MH stands for machine hour): This means that the estimated manufacturing overhead cost per machine hour is $10.00.

2. $17.50 / MH: This indicates that the estimated manufacturing overhead cost per machine hour is $17.50.

3. $20.00 / MH: This implies that the estimated manufacturing overhead cost per machine hour is $20.00.

4. $32.86 / MH: This shows that the estimated manufacturing overhead cost per machine hour is $32.86.

Each rate represents the estimated cost of manufacturing overhead per unit of the allocation base (machine hour) and is used to allocate overhead costs to products or services based on their usage of the allocation base.

The specific rate chosen depends on the nature of the business, its cost structure, and the accuracy of the estimated overhead costs.

The correct question is ''What is the predetermined overhead rate?\(\( \$ 10.00 / \mathrm{MH} \) \( \$ 17.50 / \mathrm{MH} \) \( \$ 20.00 \) / MH \( \$ 32.86 / \mathrm{MH} \)\).''

The Central Limit Theorem (CLT) is a fundamental concept in statistics that describes the behavior of sample means when the sample size is large. According to the CLT, the distribution of sample means approaches a normal distribution regardless of the shape of the original population distribution, given certain conditions.

Option A states that each individual measurement must be normally distributed. This is not a necessary condition for the CLT to hold. The original population distribution does not have to be normal; it can be any distribution shape.

Option B states that each individual measurement must be identically distributed. This is not a necessary condition for the CLT to hold. The measurements can have different distributions, as long as they satisfy the other conditions.

Option C states that each individual measurement must be independent of every other measurement. This is a necessary condition for the CLT to hold. The independence of measurements ensures that each observation contributes to the overall sample mean independently, without being influenced by other observations.

4. BC = CB.

Explanation:

1. If the product of two matrices AB equals the zero matrix, it implies that at least one of the matrices A or B (or both) must be the zero matrix for the product to result in zero.

4. The statement BC = CB states that the order of multiplication of matrices B and C does not affect the resulting matrix. This property holds true for matrices of any size as long as the dimensions are compatible for matrix multiplication.

The other statements are not necessarily true in general:

2. Both BC and CB being square matrices is not guaranteed. The product of two matrices can result in a square matrix only if the number of columns of the first matrix is equal to the number of rows of the second matrix. In this case, B has 3 columns and C has 2 rows, so BC and CB are not square matrices.

3. The matrix A + BC is not defined since the addition of matrices requires them to have the same dimensions. In this case, A is a 2×2 matrix, while BC is a 2×3 matrix, so they cannot be added together.
