Answer:   This tribute was to prevent Minos starting a war after Minos’ son, Androgens, was killed in Athens by unknown assassins during the games. Theseus volunteered to be one of the men, promising to kill the Minotaur and end the brutal tradition.

Step-by-step explanation:

Have a good day!!

The values of the function are,

⇒ fx = -y⁻²/(1 + (1/x²y⁴)), fy = -2xy⁻³/(1 + (1/x²y⁴)), and fz = 0.

Now, let's find the partial derivative of f(x, y, z) with respect to x, y, and z as:

f (x, y, z) = tan ⁻¹ (1/x²y⁴)

Hence, We get;

⇒ ∂f/∂x = -y⁻²/(1 + (1/x²y⁴))

⇒ ∂f/∂y = -2xy⁻³/(1 + (1/x²y⁴))

⇒ ∂f/∂z = 0

Therefore, the gradient of f(x, y, z) is:

∇f = (∂f/∂x)i + (∂f/∂y)j + (∂f/∂z)k = (-y⁻²/(1 + (1/x²y⁴)))i + (-2xy⁻³/(1 + (1/x²y⁴)))j + 0k

The domain of the function h(t) = -16t² + 88t is equal to [0 , 5 ].

Function is equal to,

h(t) = -16t² + 88t

Where 't' represents the time in seconds after kick

The domain of a function is the set of all possible values of the independent variable for which the function is defined.

Only independent variable is t.

And there are no restrictions on its value.

Since the function represents the height of a football in feet.

The domain should be restricted to the time when the ball is in the air.

From the time of the kick until the time when the ball hits the ground.

The ball hits the ground when its height is 0.

So, the function h(t) = 0

Solve for t to get the time when the ball hits the ground,

⇒ -16t² + 88t = 0

⇒ -16t(t - 5.5) = 0

⇒ t = 0 or t = 5.5

The ball is kicked at t = 0.

So the appropriate domain for this situation is,

0 ≤ t ≤ 5.5

Therefore, the appropriate domain of the function h(t) is for all values of t between 0 and 5.5 seconds (inclusive).

The adjusted R squared is used when we are doing multiple regression

True.

In multiple regression analysis, there are usually several independent variables that are used to predict a single dependent variable. The adjusted R squared is a statistical measure that is commonly used to assess the goodness of fit of a multiple regression model. It is a modified version of the R squared statistic, which represents the proportion of variance in the dependent variable that can be explained by the independent variables.

The adjusted R squared is useful when working with multiple regression models because it takes into account the number of independent variables included in the model. As the number of independent variables increases, the R squared value can increase even if the model does not fit the data well. The adjusted R squared adjusts for this by penalizing the R squared value for every additional independent variable included in the model.

The adjusted R squared is therefore a more reliable measure of the goodness of fit of a multiple regression model than the R squared statistic alone. It helps to ensure that the model is not overfitting the data and that the independent variables included in the model are truly contributing to the prediction of the dependent variables.

Each membership plan costs $65 if Austen takes 6 classes per month.

Let's write a system of equations to describe the situation, solve it using substitution, and fill in the blanks.

Let x be the number of classes Austen takes per month, and y be the total cost of the membership plan.

For the first membership plan, the equation is:

y = 47 + 3x

For the second membership plan, the equation is:

y = 41 + 4x

Since both plans cost the same total amount, we can set the equations equal to each other and solve for x:

47 + 3x = 41 + 4x

In order to find x, follow these steps:

1. Subtract 3x from both sides:

47 = 41 + x

2. Subtract 41 from both sides:

6 = x

3. Now we know that Austen takes 6 classes per month. Let's plug the value of x back into one of the equations to find the total cost (y). We can use the first equation:

y = 47 + 3(6)

The probability of a z-score less than 2.357 is 0.9906.

To use the normal approximation, we need to check that the sample size is sufficiently large and that the population proportion is not too close to 0 or 1. In this case, n*p = 58.5 and n*(1-p) = 19.5, which are both greater than 10, so the normal approximation is valid.

We can find the mean and standard deviation of the sampling distribution using the formulas mu = n*p = 58.5 and sigma = sqrt(n*p*(1-p)) = 4.031.

Then we can standardize X using the formula z = (X - mu)/sigma = (68 - 58.5)/4.031 = 2.357.

the cat's temp can be between    101.2 + 1.3 = 102.5   and   101.2 -1.3 = 99.9

  so   answer C shows this difference in absolute value

The requried,  |t − 101.2| ≤ 1.3 represents the normal temperature range of a cat, where t represents body temperature. Option C is correct

The absolute value function is a mathematical function that returns the positive value of a given number, regardless of whether the input is positive or negative. It is denoted by two vertical bars around the number, such as |x|.

|t − 101.2| ≤ 1.3 represents the normal temperature range of a cat, where t represents body temperature.

The average temperature of a cat is given as 101.2°F, and it can vary by as much as 1.3°F.

In order to use the simple formula, the sample size should be large enough to ensure that both the sample proportion and the complement of the sample proportion (1 - sample proportion) are at least 5. In this case, 192 and 58 are both greater than 5, so the qualification is met.

The sample proportion of students who travel to school by car is 192/250 or 0.768.

To calculate the standard error using the simple formula, we use the formula:

Standard Error = Square Root [(Sample Proportion * (1 - Sample Proportion)) / Sample Size]

Plugging in the values, we get:

Standard Error = Square Root [(0.768 * (1 - 0.768)) / 250]
= 0.034

To calculate the simple version of the 95% confidence interval, we use the formula:

CI = Sample Proportion ± (Z * Standard Error)

Where Z is the z-score associated with the desired level of confidence. For a 95% confidence interval, Z is 1.96.

Plugging in the values, we get:

CI = 0.768 ± (1.96 * 0.034)
= 0.701 to 0.835

Interpreting this CI, we can say with 95% confidence that the true proportion of students who travel to school by car in the population lies between 0.701 and 0.835.

An example of a sequence that a. Converges is an = 1/n and that b. Diverges an = n

The two potential examples of a sequence {an} with n=1 to infinity that converges and diverges:

a. Converges: A sequence that converges is one where the terms approach a finite limit as n goes to infinity. An example is the sequence an = 1/n. As n increases, the terms get smaller and approach 0, which is the limit.

b. Diverges: A sequence that diverges is one where the terms do not approach any finite limit as n goes to infinity. An example is the sequence an = n. As n increases, the terms also increase without bounds, so the sequence diverges.

The sum of moneylent out at interest 20 %per annum for 1 and a half year the compound interest reconked yearly and and recokned yearly half is 178.75 is 16250.

Let sum be p. Here r = 20%, n =3/2 yrs = 1 1/2 yrs.

When compounded yearly i.e. A.

A = p(1+r/100) * [1+{1/2 r}/100)]

= p(1+20/100) * [1+{1/2 *20}/100]

= p x 6/5 x 11/10 = 33p/25

Compound interest = A - p

= 33p/25 - p

= 8p/25

Now when compounded half yearly, then

A = p[1+(1/2 x r)/100]ⁿ*²

= p[1+(1/2 x 20)/100]⁽³/²⁾*²

= p[11/10]³

= 1331p/1000

Compound interest = 1331p/1000 - p = 331p/1000.

Now as per questions,

331p/1000 - 8p/25 = 178.75

p x 11/1000 = 178.75

p = 178.75 x 1000/11

p = 16250

Hence, the sum of moneylent out at interest 20 %per annum for 1 and a half year the compound interest reconked yearly and and recokned yearly half is 178.75 is 16250.

True: A neural network with one hidden layer can be used to solve the XOR problem.

False: While using a squared loss function and the sigmoid activation function can create a predictive model with neural networks, it does not guarantee an efficient one.

The XOR problem is a non-linear classification problem, and a neural network with one hidden layer can learn non-linear decision boundaries. By using appropriate weights and activation functions (e.g., sigmoid or ReLU) in the hidden layer, the network can effectively represent and solve the XOR problem.

The combination of squared loss and sigmoid activation can lead to vanishing gradient issues, making the learning process slow and prone to getting stuck in local minima. Instead, using alternative loss functions (e.g., cross-entropy) and activation functions (e.g., ReLU) may lead to a more efficient predictive model.

Lift (Fastest Engine → 3 Year Warranty) = Confidence (Fastest Engine → 3 Year Warranty) / Support (3-Year Warranty) for the automobile.

To calculate support, confidence, and lift for Rule 1, follow these steps:

Step 1: Calculate support for Rule 1
Support is the probability of both events (Fastest Engine and 3-Year Warranty) occurring together. To calculate support, divide the number of instances where both events occur by the total number of instances in the dataset.

Support (Fastest Engine → 3 Year Warranty) = (Number of instances with Fastest Engine and 3-Year Warranty) / (Total instances in the dataset)

Step 2: Calculate confidence for Rule 1
Confidence is the probability of 3-Year Warranty, given Fastest Engine. To calculate confidence, divide the number of instances where both events occur by the number of instances where Fastest Engine occurs.

Confidence (Fastest Engine → 3 Year Warranty) = (Number of instances with Fastest Engine and 3-Year Warranty) / (Number of instances with Fastest Engine)

Step 3: Calculate lift for Rule 1
Lift is the ratio of confidence to the support of the event being predicted (3-Year Warranty). To calculate lift, divide the confidence of the rule by the support of 3-Year Warranty.

Lift (Fastest Engine → 3 Year Warranty) = Confidence (Fastest Engine → 3 Year Warranty) / Support (3-Year Warranty)

Make sure to round your answers to three decimal places.

Note: To provide the exact numerical values for support, confidence, and lift, the specific data from the Automobile Options dataset is needed. The steps above outline the process of how to calculate these values.

The solution to the given differential equation with the given initial conditions is y = 4x^3 + 5x + 3.

To solve for y, we need to integrate the given differential equation twice with respect to x, using the initial conditions to determine the constants of integration.

Integrating y'' = 24x once gives us y' =[tex]12x^2 + C1,[/tex] where C1 is the constant of integration. Using the condition y'(0) = 5, we can solve for C1 as follows:

y'(0) = [tex]12(0)^2 + C1[/tex]

5 = C1

So, we have y' =[tex]12x^2 + 5.[/tex]

Integrating y' =[tex]12x^2 + 5[/tex] once more gives us y =[tex]4x^3 + 5x + C2[/tex], where C2 is the constant of integration. Using the condition y(0) = 3, we can solve for C2 as follows:

y(0) = [tex]4(0)^3 + 5(0) + C2[/tex]

3 = C2

So, we have y =[tex]4x^3 + 5x + 3.[/tex]

The area of quadrilateral ABCD is 23.5 square units, which is equivalent to approximately 27.99 square yards.

How to solve the question?

To determine if the plot of land defined by quadrilateral ABCD will work for the traveling circus, we need to calculate its area.

To do this, we can use the Shoelace Formula, also known as the Surveyor's Formula, which can be applied to any polygon with vertices given in Cartesian coordinates.

The Shoelace Formula is based on the fact that the area of a polygon with vertices (x1, y1), (x2, y2), ... , (xn, yn) is equal to half the absolute value of the sum of the products of the x-coordinates of adjacent vertices subtracted from the sum of the products of the y-coordinates of adjacent vertices, as shown below:

Area = 1/2 * |(x₁ * y₂+ x₂* y₃ + ... + xₙ₋₁ * yₙ + Xₙ* y₁) - (y₁ * x₂ + y₂ * x₃ + ... + yₙ₋₁* xₙ + y * x₁)|

Applying this formula to the vertices of ABCD, we get:

Area = 1/2 * |(-2 * 5 + 4 * -2 + 3 * -4 + -3 * -3) - (-3 * 5 - 4 * 3 - 3 * 4 - 2 * -2)|

Area = 1/2 * |-10 - 37|

Area = 1/2 * 47

Area = 23.5

The area of quadrilateral ABCD is 23.5 square units, which is equivalent to approximately 27.99 square yards. Therefore, the plot of land determined by ABCD is large enough to meet the traveling circus's requirement of at least 45 square yards, and it will work for their show.
