The true proportion of females within undergraduate economics programs, denoted by \(\( p \)\), can be estimated using the sample proportion, denoted by \(\( \hat{p} \)\). The variance of \(\( \hat{p} \)\), assuming that the observations are independent and identically distributed (iid), can be determined as follows:

\(\( \text{Var}(\hat{p}) = \frac{p(1-p)}{n} \)\)

where \(\( n \)\) represents the sample size.

The sample proportion \(\( \hat{p} \)\) is calculated by dividing the number of females in the sample by the total sample size. Since we assume that the observations are iid, the variance of \(\( \hat{p} \)\) can be derived using basic properties of variance.

To determine the variance of \(\( \hat{p} \)\), we use the formula \(\( \text{Var}(X) = E(X^2) - [E(X)]^2 \)\). In this case, \(\( X \)\) represents the random variable corresponding to the proportion of females in a single observation.

The expected value of \(\( X \)\) is \(\( p \)\), and the expected value of \(\( X^2 \)\) is \(\( p^2 \)\). Therefore, we have \(\( \text{Var}(X) = E(X^2) - [E(X)]^2 = p^2 - p^2 = p(1-p) \)\).

Since \(\( \hat{p} \)\) is an average of \(\( n \)\) independent observations, the variance of \(\( \hat{p} \)\) is given by \(\( \text{Var}(\hat{p}) = \frac{\text{Var}(X)}{n} = \frac{p(1-p)}{n} \)\).

Answer:

x=18

<W=109 degrees

Step-by-step explanation:

Since the two angles are supplementary, they equal 180 degrees, so you can set up the equation like this:

3x+17+6x+1=180

Then combine like terms:

(3x+6x)+(17+1)=180

9x+18=180

subtract 18 from both sides:

9x+18(-18)=180(-18)

9x=162

divide each side by 9:

9x(/9)=162(/9)

x=18

18 is one of your answers.

To find angle W, first plug in the value of x into the equation:

6x+1

6(18)+1

Simplify:

If the force is changed to 40 N,  the acceleration of the object will be 4 m/s².

The given parameters are;

The acting force ∝ The acceleration of the object.

The acceleration given by an amount of force, F, of 30 N = 3 m/s²

According to Newton's Second Law of motion, we have;

F = m·a

Where;

m = The mass of the object

Therefore, we have;

mass = force/ acceleration

From the conditions, F = 30 N, when a = 3 m/s², we have, the mass of the given object is given as follows;

m = F/a

Step-by-step explanation:

We could use the combined rate equation to find the combined rate of work.

Combined rate of work formula: \(\frac{1}{t_{b}} = \frac{1}{t_{1} } + \frac{1}{t_{2} }\), where \(t_{1}\) is the individual time for object A, \(t_{2}\) the individual time for object B and \(t_{b}\) is the time for A and B together.

The time it takes Irina to paint the room alone, \(t_{1}\) = 5 hours

The time it takes Paulo to paint the room, \(t_{2}\) = 10 hours

1) Substitute object A (Irina) and B (Paulo) into the formula given above, and change \(t_{b}\) into an \(x\).

\(\frac{1}{{x}} = \frac{1}{5 } + \frac{1}{10 }\)

2) Add the fractions.

\(\frac{1}{x} = \frac{3}{10}\)

3) Solve for the \(x\).

\(x(3) = 1(10)\\3x = 10\\x = \frac{10}{3} \\\)

The outcome of the specified expression 21 - {8 - 5 [6 - 4 (8 - 7 ) - 9(4 - 5 )} - 10 + 25 x 2 + 13 } = 121

To evaluate the given expression, let's break it down into smaller steps and follow the order of operations (PEMDAS/BODMAS):

Evaluate the innermost parentheses first.

Inside the parentheses, we have:

(8 - 7) = 1

(4 - 5) = -1

So the expression becomes:

21 - {8 - 5 [6 - 4 * 1 - 9 * (-1)]} - 10 + 25 * 2 + 13

Simplifying further:

21 - {8 - 5 [6 - 4 + 9]} - 10 + 25 * 2 + 13

21 - {8 - 5 [11]} - 10 + 25 * 2 + 13

21 - {8 - 55} - 10 + 25 * 2 + 13

21 - {-47} - 10 + 25 * 2 + 13

Evaluate the square brackets next.

Inside the square brackets, we have:

5 * [11] = 55

So the expression becomes:

21 - {-47} - 10 + 25 * 2 + 13

21 + 47 - 10 + 25 * 2 + 13

Perform the multiplication and division from left to right.

25 * 2 = 50

The expression now becomes:

21 + 47 - 10 + 50 + 13

Perform the addition and subtraction from left to right.

21 + 47 = 68

68 - 10 = 58

58 + 50 = 108

108 + 13 = 121

Therefore, the final result of the given expression:

21 - {8 - 5 [6 - 4 (8 - 7 ) - 9(4 - 5 )} - 10 + 25 x 2 + 13 } = 121

Lasso, ridge regression, and random forest approach that are suggested in the article could be applied to Malaysia. Lasso and ridge regression are regression models that are used to prevent overfitting, which is common when there are many predictors and few observations. Random forest is a decision tree-based model that is used for classification and regression analysis.

The study by Ashraf and Khan (2018) aimed to predict the economic growth of Malaysia by using regression models. The study used the Lasso regression model as it has been used for feature selection, where it can automatically remove unnecessary predictors from the model, and is good at handling multicollinearity. The study concluded that Lasso regression was the best model to predict economic growth in Malaysia.

In another study by Rizwan et al. (2017), it was found that random forest could be used to predict crime rates in Malaysia with a high degree of accuracy. In a study by Sulaiman et al. (2020), it was found that ridge regression can be used to predict the performance of Islamic banking institutions in Malaysia.

To conclude, Lasso, ridge regression, and random forest models have been applied successfully in Malaysia to predict economic growth, crime rates, and the performance of Islamic banking institutions.
