Two events that are disjoint are not independent. This is because that disjoint events do not overlap, which means that if one event occurs, the other cannot. So, the occurrence of one event provides information about the absence of the other, which violates the definition of independence.

Two events A and B are considered independent if the occurrence of A has no effect on the likelihood of B occurring, and vice versa.

In other words, the probability of both events happening at the same time is equal to the product of their individual probabilities:

\(P(A and B) = P(A) * P(B) (B).\)

This formula cannot be satisfied when two events are disjoint because if one event occurs, the other cannot occur. As a result, two disjoint events are not independent.

With the confidence interval, it can be concluded with 99% confidence that the true proportion of teenage drivers in Atlanta who text while driving lies between 35.89% and 75.23%.

The confidence interval (CI) is equal to the sample proportion (p) plus or minus the product of the critical value (z*) and the standard error of the proportion, where the standard error is calculated by taking the square root of the product of the sample proportion, its complement (1 - p), and the reciprocal of the sample size (n), formed in an equation.

where:

p is the sample proportion (15/27 in this case)

z* is the critical value from the standard normal distribution for the desired confidence level (99% in this case, which corresponds to a z* value of 2.576)

n is the sample size (27 in this case)

Substituting the given values, we get:

CI = 0.5556 ± 2.576*√((0.5556(1-0.5556))/27)

Simplifying this expression, we get:

CI = 0.5556 ± 0.1967

So the 99% confidence interval for the population proportion of teens who text while driving is:

(0.3589, 0.7523)

Therefore, we can be 99% confident that the true proportion of teenage drivers in Atlanta who text while driving lies between 35.89% and 75.23%.

Step-by-step explanation:

The probability that the document will reach its destination through service B, given that it has already reached its destination through service A, is 0.8.

The conditional probability we are looking for is P(B | A) where B is the document reaching its destination through service B and A is the document reaching its destination through service A.

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

We know that the document has already reached its destination through service A,

therefore P(A) = 1.

The probability that it will also reach its destination through service B is the conditional probability P(B | A).

Therefore, P(B | A) = P(A and B) / P(A) can be simplified to P(B | A) = P(A ∩ B) / P(A)

where P(A ∩ B) is the probability that the document reaches its destination through both service A and service B.

Let's assume that the probability of the document reaching its destination through service A is 0.9 and the probability of the document reaching its destination through service B is 0.8.

The probability of the document reaching its destination through both services A and B is the product of the probabilities P(A) and P(B) which is 0.9 x 0.8

= 0.72.

Substituting these values in the equation P(B | A) = P(A ∩ B) / P(A) gives us:

P(B | A) = 0.72 / 0.9 = 0.8

Therefore, the probability that the document will reach its destination through service B,

given that it has already reached its destination through service A, is 0.8.

The surface area of the prism is 256 square inches when the dimensions of the rectangular base are 8 inches by 12 inches and the height is 2 inches.

To calculate the surface area of a prism, we need to find the area of each face and add them together. Since this prism has a rectangular base, it has two identical rectangular faces and four identical rectangular side faces. The dimensions of the rectangular base are 8 inches by 12 inches, so the area of each rectangular face is 8 inches x 12 inches = 96 square inches.

The height of the prism is given as 2 inches, so the area of each rectangular side face is 2 inches x 8 inches = 16 square inches. There are four side faces, so the total area of the side faces is 4 x 16 square inches = 64 square inches.

Therefore, the total surface area of the prism is the sum of the areas of the two rectangular faces and the four side faces: Total surface area = 2 x 96 square inches + 4 x 16 square inches
Total surface area = 192 square inches + 64 square inches
Total surface area = 256 square inches

The area of the rectangle is increasing at a rate of 166 cm^2/s when the length is 15 cm and the width is 13 cm.

To find the rate at which the area of the rectangle is increasing, we need to use the formula for the area of a rectangle, which is A = lw (where A is the area, l is the length, and w is the width).

We can differentiate both sides of the equation with respect to time (t) to obtain:

dA/dt = (dl/dt)w + l(dw/dt)

Here, dl/dt is the rate of change of the length, which is given as 7 cm/s, and dw/dt is the rate of change of the width, which is given as 5 cm/s.

We can substitute these values along with the given values of length and width (l = 15 cm and w = 13 cm) to obtain:

dA/dt = (7 cm/s)(13 cm) + (15 cm)(5 cm/s)

dA/dt = 91 cm^2/s + 75 cm^2/s

dA/dt = 166 cm^2/s

When a crucial variable is excluded from a regression model, the results are referred to as omitted variable bias.

Regression analysis frequently encounters the issue of omitted variable bias, which occurs when an important independent variable is left out of the model and affects the estimates of the coefficients for the included variables.

This happens because one or more of the included independent variables as well as the dependent variable may be correlated with the variable that was left out. As a result, the intercept and coefficients of the included independent variables may be overestimated or underestimated.

Based on prior knowledge and theory, researchers should carefully consider which variables to include in the model to address this issue. They should then test for potential correlations between the included and

For the two independent events A and B when the probability of A is 0.2 and the probability of B is 0.3 then probability of P (A/B) = 0.2.

As given in the question,

Given probability of event A is equal to 0.2

Probability of event B is equal to 0.3

Both the given events A and B are independents events.

Required probability is given by :

P ( A / B ) = P ( A ∩ B ) / P( B )  __(1)

As both the events are independent we get,

P ( A ∩ B ) = P ( A ) × P ( B )     ___(2)

Substitute (2) in (1) we get,

P ( A / B ) = P ( A ) × P ( B ) / P( B )

⇒ P ( A / B ) = P ( A )

⇒  P ( A / B ) = 0.2

The rule of the rotation to the right is a rotation by 90° clockwise about the origin.

We need to describe the rule of the rotation to the right.

A figure and its rotation keep the same shape and size but face in a new direction. A figure can be rotated in either a clockwise or counterclockwise direction. The angle of rotation is the measure of how far a figure is rotated about its centre of rotation. The angle of rotation is often expressed in degrees. We specify the rotation's degree measure and direction.

If the rotation is applied to the right, it means a rotation of 90° in a clockwise direction about the origin.

Divergence criteriaIn mathematics, the Divergence criterion is a theorem that is used to establish the divergence or convergence of a series.

To use this criterion, one needs to observe if the limit of the series terms is zero as n approaches infinity, and if it does not, then the series will diverge.

Therefore, if a limit of the sequence does not exist or is not equal to L, then the series is said to diverge.

The Divergence criterion states that if the limit of the sequence of terms of a series is not equal to 0, the series will not converge.

This is a necessary but not sufficient condition for convergence.

Therefore, for a series to converge, its sequence of terms must approach 0.

To show that (a) f(x) does not have a limit at 0, where x < 0 f(x) = -{ x > 0}, we use the Divergence criterion.

Let's suppose that the limit of f(x) as x approaches 0 exists.

Therefore, we have limx→0- f(x) = limx→0+ f(x).

Since f(x) = -1 for x < 0, and f(x) = 1 for x > 0, then we have limx→0- f(x) = -1 and limx→0+ f(x) = 1.

Hence, we get a contradiction and we can conclude that f(x) does not have a limit at 0, where x < 0 f(x) = -{ x > 0}.

To show that (b) f(x) does not have a limit at 0, where 1 f(x) = sin 7.C,

we use the Divergence criterion. Let's suppose that the limit of f(x) as x approaches 0 exists. Therefore, we have limx→0 f(x) = L.

If L exists, then we can write it as limx→0 f(x) = limx→0 sin(7/x) / (1/x) = limx→0 (7 cos(7/x)) / (-1/x²).

Simplifying, we get limx→0 f(x) = limx→0 -7x² cos(7/x) = 0.

Since the limit is equal to 0, we cannot use the Divergence criterion to determine whether the series converges or diverges.

Therefore, we need to use another test to determine the convergence or divergence of the series.

The covariance for the new data will be 1.4641 times the original covariance.

Let X and Y be two variables with a covariance cov(X, Y).

We can consider the data set S = {(x1, y1), (x2, y2), ..., (xn, yn)},

where xi and yi are the i-th values of X and Y.

Also,

let S' = {(1.21x1, 1.21y1), (1.21x2, 1.21y2), ..., (1.21xn, 1.21yn)} be the data set obtained by multiplying each value in S by 1.21.

To find the covariance of S', we use the formula cov(aX, bY) = ab cov(X, Y) for constants a and b.

Here, we have a = b = 1.21,

so we can write:

cov(S') = cov(1.21X, 1.21Y)

= 1.21 * 1.21 * cov(X, Y)

= 1.4641 * cov(X, Y)

Therefore, the covariance for the new data will be 1.4641 times the original covariance.

This is because covariance is a measure of the linear relationship between two variables, and scaling one or both variables by a constant multiplies the covariance by the square of that constant, as shown by the formula above.
