Because of Probability we can say that, drawing a card that is an ace or a 2 and rolling two dice that both land on even numbers are compound events as they involve two possible outcomes.

Probability is the study of the chances of occurrence of a result, which are obtained by the ratio between favourable cases and possible cases. One of the fields of mathematics called as probability deals with calculating the possibility of experiments occurring. With a probability, we can calculate everything from the probability of obtaining a head or a tail when flipping a coin to the probability of making a research error, for example.

The events that are compound events are:

Choose an ace or even a two from the deck.

two dice are rolled, and both come up even.

An event that is made up of two or even more simple occurrences is referred to as a compound event.

Rolling a die that lands on 4 and flipping a coin that lands on heads are simple events because they each involve only one action.

Drawing a card that is an ace or a 2 and rolling two dice that both land on even numbers are compound events because they each involve two possible outcomes.

The sample size required for the true proportion of students who have parents who have remarried is 607.

What is termed the Confidence Interval?

The confidence interval is indeed the range of values within which you expect your forecast to fall a certain proportion of the time if you repeat your experiment or re-sample a population in the same manner.

The alpha value determines the confidence level, which is the percentage of times you anticipate reproducing an approximate between both the upper and lower limits of the confidence interval.

The above problem is based on the use of determining sample size to estimate the true percentage of students given the constraints.

We may also need to consult the table to determine the Z value.

For the given question,

α = 0.5

Consider the Z-table,

Zα/2 = Z (0.1/2)

Z (0.025) = 1.96

Let 'n' be the sample size required for the true proportion of students who have parents who have remarried.

For calculating the margin error 'E' is given 3%.

n = Z² (α/2) / E² × (P°(1 - P°))

Put the given values.

n = (1.96)² / (0.03)²  × (0.28(1 - 0.28))

On solving,

n = 4268.444(0.2016)

n = 860.51

n ≈ 860.51

Thus, the sample size required for the true proportion of students who have parents who have remarried is 860.

Answer:

125 Dolphins

Step-by-step explanation:

The number of dolphins varied linearly with the number of fish.

The number of dolphins = D

The number of fish = F

Hence:

D ∝ F

D = kF

When 400 fish were present 250 dolphins appeared

Solving for k

250 = 400k...... Equation 1

Also

when 300 fish were present, 200 dolphins appeared.

200 = 300k...... Equation 2

So: we find k = Constant of Proportionality

250 = 400k...... Equation 1

200 = 300k...... Equation 2

We Subtract Equation 2 from Equation 1

50 = 100k

k = 50/100

k = 1/2

How many dolphins would appear if 250 fish were present?

D = kF

D = 1/2 × 250

D = 125 Dolphins

The rule represents the translation from the pre-image, ΔABC, to the image, ΔA'B'C' is (x, y) → (x + 7, y - 6).

When a line is translated, it means the line is moved from one position to another. The coordinate for triangle ABC are A(-3 ,4) , B(-4,1) and C(-2,1).

The coordinate of triangle A'B'C' is A'(4,-2), B'(3,-5), and C'(5,-5).

From above, it can be seen that the image A'B'C' is obtained from the pre-image ABC by translating the vertices of the image by 7 units to the right and 6 units down.

Therefore, the rule represents the translation from the pre-image, ΔABC, to the image, ΔA'B'C' is (x, y) → (x + 7, y - 6)

Hence, the rule represents the translation from the pre-image, ΔABC, to the image, ΔA'B'C' is (x, y) → (x + 7, y - 6).

To find the value of x where the slope of the tangent line is equal to 5, we need to take the derivative of the function y = x^2 - 3x + 2, which is y' = 2x - 3. Then, we can set y' equal to 5 and solve for x: 2x - 3 = 5 2x = 8 x = 4 Therefore, the answer is b. 4.

To find the value of x where the slope of the tangent line is equal to 5 for the function y = x^2 - 3x, we need to first find the derivative of the function, which represents the slope of the tangent line at any point.

Derivative of y = x^2 - 3x:
y' = 2x - 3

Now, we set the derivative equal to 5 to find the value of x:

5 = 2x - 3

Solving for x:

8 = 2x
x = 4

So the correct answer is b. 4, as the slope of the tangent line is equal to 5 when x = 4.

To find out how much the painter charged for the last job, we need to substitute h=15 and c=3 in the expression 35h 30c and simplify. The painter charged $615 for the last job which required 3 cans of paint and took 15 hours to complete.

The painter uses the expression 35h + 30c to determine the cost of a job, where h represents the hours spent and c represents the number of paint cans used. In the last job, it took the painter 15 hours and 3 cans of paint to complete the work. To find the cost, we will plug these values into the given expression.
Cost = 35h + 30c
Cost = 35(15) + 30(3)
Now, we will perform the calculations:
Cost = 525 + 90
By adding these values, we get the total cost:
Cost = 615

False. A parsimonious model is one that achieves simplicity and explanatory power by using the fewest number of variables or predictors necessary to explain the phenomenon of interest.

It prioritizes simplicity and elegance over including excessive or unnecessary predictors.

In a parsimonious model, the focus is on selecting the most relevant and impactful predictors rather than including a large number of weak predictors. By including only strong predictors, a parsimonious model aims to minimize overfitting, improve interpretability, and enhance generalizability.

Including many weak predictors in a model may lead to a loss of parsimony as it introduces unnecessary complexity without necessarily improving the model's performance or explanatory power. Therefore, a parsimonious model typically emphasizes the importance of selecting a few strong predictors that provide meaningful and significant contributions to the model's overall performance.

If x² - 8 = x² substracting x² on both side then k = -8. This indicates that to obtain g, we must shift f 8 units down.

An expression, rule, or law in mathematics that establishes the relationship between an independent variable and a dependent variable (the dependent variable). In mathematics, functions are everywhere, and they are crucial for constructing physical relationships in the sciences.

Let the two functions be f(x) = x² and g(x) = x² - 8.

We know that g exists obtained by shifting f, k units up or down (depending of the value of k, if positive, the shifting is up, or down otherwise). At any point x, we get g(x) by adding k units to the value of f(x). That is

g(x) = f(x) + k

If we replace the meaning of f, g we get

x² - 8 = x²

By substracting x² on both side we get

x² - 8 - x² = x² - x²

k = -8.

This indicates that to obtain g, we must shift f 8 units down.

A linear-quadratic state estimator and a particle filter are both estimation techniques used in control systems, but they differ in their underlying principles and application domains.

A linear-quadratic state estimator, often referred to as a Kalman filter, is a widely used optimal estimation algorithm for linear systems with Gaussian noise. It assumes linearity in the system dynamics and measurements. The Kalman filter combines the predictions from a mathematical model (state equation) and the available measurements to estimate the current state of the system. It provides a closed-form solution and is computationally efficient. However, it relies on linear assumptions and Gaussian noise, which may limit its effectiveness in nonlinear or non-Gaussian scenarios.

On the other hand, a particle filter, also known as a sequential Monte Carlo method, is a non-linear and non-Gaussian state estimation technique. It employs a set of particles (samples) to represent the posterior distribution of the system state. The particles are propagated through the system dynamics and updated using measurement information. The particle filter provides an approximation of the posterior distribution, allowing it to handle non-linearities and non-Gaussian noise. However, it is computationally more demanding than the Kalman filter due to the need for particle resampling and propagation.

The choice between a linear-quadratic state estimator and a particle filter depends on the characteristics of the system and the nature of the noise. The Kalman filter is suitable for linear and Gaussian systems, while the particle filter is more versatile and can handle non-linearities and non-Gaussian noise. However, the particle filter's computational complexity may be a limiting factor in real-time applications.

In summary, a linear-quadratic state estimator (Kalman filter) is a computationally efficient estimation technique suitable for linear and Gaussian systems. A particle filter, on the other hand, provides more flexibility by accommodating non-linearities and non-Gaussian noise but requires more computational resources. The choice between these methods depends on the specific system characteristics and the desired accuracy-performance trade-off.
