Answer and explanation:

Given that 1/2cm= 1 foot

5cm= 2×5=10 feet

Length is twice the width, therefore real length of shape = 10×2=20 feet

Perimeter is sum of all sides= 20 feet+20 feet+10 feet+10 feet = 60 feet

Therefore Deana's Patio= 60 feet in real length

The correct option is c) Easier interpretation. One of the main advantages of simple models is their ease of interpretation. Simple models tend to have fewer parameters and less complex mathematical equations, making it easier to understand and interpret how the model is making predictions.

This interpretability can be valuable in various domains, such as medicine, finance, or legal systems, where it is important to have transparent and understandable decision-making processes.

Complex models, on the other hand, often involve intricate relationships and numerous parameters, which can make it challenging to comprehend the underlying reasoning behind their predictions. While complex models can sometimes offer higher accuracy or make more detailed predictions, they often sacrifice interpretability in the process.

The statement that the variance of sample estimator varies directly with variance of x and inversely with the sample size is true about the variance of the sample estimator. So, option(a) is correct answer for this question.

Estimators are statistics used to estimate unknown parameters. In statistics, an estimator is a function that associates a parameter estimate with each possible sample that we can observe. Also, variance or variance estimation in sampled estimators is a statistical inference problem in which a sample is used to produce a point estimate of the variance of an unknown distribution.

Variance defines a distribution or a measure of distribution in a data set. There are two types:

Sampling variance, for a data sample of size n, the calculation method is

\(s² = ∑_{ i = 1} ^{ \ \: n } \frac{(x_i− \bar x)²}{n - 1}\)

From the above relation we conclude that the variance is proportional to the change in the observed value, that is, x and the change becomes Inverse sample size, n. Therefore, the variance of the sample estimator proportional to the variance of x and inversely proportional to the sample size is the correct answer.

In the given public good provision game, player 1's expected payoff for contributing and not contributing depends on player 2's cutoff point (C*₂). When player 1 contributes, their payoff is v - C₁ if C₁ < C*₂, and 0 if C₁ ≥ C*₂. When player 1 does not contribute, their payoff is always 0.

In this public good provision game, player 1's decision to contribute or not contribute depends on their private cost, C₁, and player 2's cutoff point, C*₂. If player 1 contributes, they incur a cost of C₁ but gain access to the public good valued at v dollars. However, if C₁ is greater than or equal to C*₂, player 1's expected payoff for contributing would be 0 since player 2 would not contribute.

On the other hand, if player 1 does not contribute, their expected payoff is always 0, as they neither incur any cost nor receive any benefit from the public good. Therefore, player 1's expected payoff for not contributing is constant, irrespective of the cutoff point.

To determine player 1's expected payoff for contributing, we consider the case when C₁ is less than C*₂. In this scenario, player 2 contributes to the public good, allowing both players to consume it. Player 1's payoff would then be v - C₁, which represents the value of the public good minus their cost of contribution. However, if C₁ is greater than or equal to C*₂, player 1's contribution would be futile, as player 2 would not contribute. In this case, player 1's expected payoff for contributing would be 0, as they would not gain access to the public good.

In summary, player 1's expected payoff for contributing is v - C₁ if C₁ < C*₂, and 0 if C₁ ≥ C*₂. On the other hand, player 1's expected payoff for not contributing is always 0. Therefore, when C₁ is low, player 1 would prefer to contribute, as long as the cost of contribution is less than player 2's cutoff point.

Jamie has 44 pairs of shoes

Step-by-step explanation:

Let

Jamie= x pairs of shoes

Suzie= 33 less than twice the amount of shoes Jamie has

2x - 33 = 55

Solve:

2x - 33 = 55

Collect like terms

2x = 55 + 33

2x = 88

Divide both sides by 2

2x / 2 = 88 / 2

x = 44

Jamie = x = 44 pairs of shoes

Therefore, Jamie has 44 pairs of shoes

The required Matlab code to find the greatest common divisor of a number using the Euclidean algorithm is shown.

To find the greatest common divisor (GCD) of two numbers using the Euclidean algorithm in MATLAB, you can use the following code:

% Replace '12345678' with your actual student number

studentNumber = '12345678';

% Extract the first 4 digits as the first number

firstNumber = str2double(studentNumber(1:4));

% Extract the last 3 digits as the second number

secondNumber = str2double(studentNumber(end-2:end));

% Find the GCD using the Euclidean algorithm

gcdValue = gcd(firstNumber, secondNumber);

% Display the result

disp(['The GCD of ' num2str(firstNumber) ' and ' num2str(secondNumber) ' is ' num2str(gcdValue) '.']);

Make sure to replace '12345678' with your actual student number. The code extracts the first 4 digits as the first number and the last 3 digits as the second number using string indexing. Then, the gcd function in MATLAB is used to calculate the GCD of the two numbers. Finally, the result is displayed using the disp function.

So, on solving the question we can say  all sum of angles of a pentagon are 540 ; x = 340

A pentagon is a polygon with five sides that is used in geometry. The inner angles of a straightforward pentagon add up to 540°. Simple or self-intersecting pentagons are both possible. A pentagram is a self-intersecting regular pentagon. Five angles and all sides of a regular pentagon are equal. It is referred to as an irregular pentagon if the side lengths and angle measurements do not match. All outside angles, as far as we are aware, balance out inside angles. The polygon's exterior angle total is therefore equal to n(360°/n). There are five sides to a pentagon, therefore n must equal five. Consequently, 5(360°/5) = 360° is the sum of the pentagon's outer angles.

A function is simply a relationship that maps one input to one output.

Given the data in the question;

First, replace the function designators in f + g with actual functions.

( f + g )( x ) = ( f )(x) + ( g )( x )

( f + g )( x ) = ( x² + 2x ) + ( 4x² - 3 )

Remove the parenthesis

( f + g )( x ) = x² + 2x + 4x² - 3

Collect and add like terms

( f + g )( x ) = x² + 4x² + 2x  - 3

( f + g )( x ) = 5x² + 2x  - 3

The formula for y in terms of x is y = 8/x^3 and x is 1/2 when y = 64

The variation statement is given as

y is inversely proportional to the cube of x

This means that

y = k/x^3

Where k represents the constant of variation

Using the points on the table, we have

(x, y) = (1, 8)

This gives

8 = k/1^3

Evaluate

k = 8

So, we have

y = 8/x^3

Here, we have

y = 64 and y = 8/x^3

This gives

8/x^3 = 64

So, we have

x^3 = 1/8

Take the cube roots

x = 1/2

Hence, the value of x is 1/2

Answer:

B

Step-by-step explanation:

False. We do not always evaluate just the specific result obtained in an experiment.

In scientific experiments, we do not just evaluate the specific result obtained in the experiment. Instead, we evaluate the entire experimental design, including the methods used, the sample size, and the statistical analysis.

For example, suppose a researcher conducts an experiment to test a new drug's effectiveness in treating a particular disease. If the result of the experiment shows that the drug is effective, the researcher cannot simply conclude that the drug works based on this one result. Instead, the researcher must evaluate the experimental design to ensure that the result is reliable and valid.

This evaluation includes examining the study's methods to determine if they are appropriate and if the sample size is large enough to produce meaningful results. It also involves statistical analysis to assess the strength of the relationship between the treatment and the outcome and to determine if the result is statistically significant.

Therefore, evaluating just the specific result obtained in an experiment is not sufficient. We must also consider the experimental design, methods used, sample size, and statistical analysis to draw valid and reliable conclusions from the experiment.
