The recipe for fried potato fritters requires a mixture of mashed potatoes and chicken meat in the ratio 9 : 2. One kilogram of mixture yields 24 pieces of fritters. To make 198 pieces of potato fritters, you would need approximately 8.25 kilograms of chicken meat.

Given that one kilogram of the mixture yields 24 pieces of fritters, we need to find the ratio of mixture to fritters to determine the amount of mixture needed for 198 fritters.

The ratio of mixture to fritters is 1 kilogram : 24 pieces.

To find the amount of mixture needed for 198 pieces of fritters, we can set up a proportion:

1 kilogram / 24 pieces = X kilograms / 198 pieces.

Cross-multiplying, we get: 1 kilogram * 198 pieces = 24 pieces * X kilograms.

Simplifying the equation, we have: 198 = 24X.

Solving for X, we divide both sides of the equation by 24: X = 198 / 24 = 8.25 kilograms.

Since the ratio of mashed potatoes to chicken meat is 9 : 2, we can calculate the amount of chicken meat needed for 8.25 kilograms of the mixture.

The total ratio is 9 + 2 = 11 parts.

To find the amount of chicken meat, we divide 2 parts by 11 and multiply by 8.25 kilograms:

(2/11) * 8.25 kilograms = 1.5 kilograms (approximately).

Therefore, to make 198 pieces of potato fritters, you would need approximately 8.25 kilograms of chicken meat.

The type of model selection method that the scientist should use is a stepwise regression.

In statistics, stepwise regression is a method of fitting regression models in which the selection of predictive variables is done automatically. Each step considers a variable for addition to or subtraction from the set of explanatory variables based on some predetermined criterion.

To determine which predictors are significant in the model to predict movie success, we should use the step-wise regression method which is a model selection method.

Stepwise regression is a method for testing the statistical significance of each independent variable in a linear regression model iteratively. The forward selection method begins with nothing and gradually adds each new variable, testing for statistical significance along the way.

The underlying goal of stepwise regression is to identify a set of independent variables that significantly influence the dependent variable through a series of tests (e.g., F-tests, t-tests). Stepwise regression has the following advantages: The ability to manage a large number of potential predictor variables while fine-tuning the model to select the best predictor variables from among the available options. It is faster than other methods of automatic model selection.

Sabrina bought 26 first-class mail stamps and 27 additional ounce stamps.

Let the number of stamps that Sabrina bought at the first-class mail rate of $0.48 be x. So the number of stamps that Sabrina bought at the additional ounce rate of $0.22 would be 53 - x.

Now let's create an equation that reflects Sabrina's total expenditure of   $18.42.0.48x + 0.22(53 - x) = 18.42

Multiplying the second term gives:

         0.48x + 11.66 - 0.22x = 18.42

Subtracting 11.66 from both sides:

                                 0.26x = 6.76

Now, let's solve for x by dividing both sides by 0.26:

                                        x = 26

So, Sabrina bought 26 stamps at the first-class mail rate of $0.48. She then bought 53 - 26 = 27 stamps at the additional ounce rate of $0.22. Sabrina bought 26 first-class mail stamps and 27 additional ounce stamps.

There are several different sampling methods that could be employed for this study, including:

Simple random sampling: This method involves randomly selecting a certain number of students from each campus and measuring the distance between their hometowns and their campuses.

Stratified random sampling: This method involves dividing the student population at each campus into different strata (e.g. by major or year in school) and then randomly selecting a certain number of students from each stratum.

Cluster sampling: This method involves randomly selecting a certain number of campuses and then measuring the distance between the hometowns of all students at those campuses and their respective campuses.

Multi-stage sampling: This method involves using a combination of the above methods, such as first using cluster sampling to select a certain number of campuses and then using stratified random sampling to select a certain number of students from each campus.

This study would be an enumerative study because it seeks to measure the characteristics of a population, in this case, the average distance between the hometowns of students and their campuses, by counting and measuring them.

It is not an analytic study because it doesn't involve testing a hypothesis or making causal inferences.

In a family with five girls and the probability of a boy being born is 1/2, the probability of the next child being a boy is still 1/2.

The previous births do not affect the probability of the next birth since each birth is an independent event.

The probability of an event occurring is determined by the ratio of the number of favorable outcomes to the total number of possible outcomes. In this case, the event of interest is the birth of a boy.

Since each birth is an independent event, the probability of having a boy on any given birth is always 1/2, regardless of the previous children born.

In the given scenario, the family already has five girls. This information is not relevant to the probability of the next child being a boy. The gender of the previous children does not affect the probability of the next child being a boy or a girl.

Therefore, the probability of the next child being a boy remains 1/2, as it is for any independent birth event.

Here we have the system:

x + 3y > -3

y < x + 1

First, we should write both in linear form, the second one is already on that form, so we need to transform the first one.

x + 3y > -3

3y > -x - 3

y > (1/3)*-x - 3/3

y > -x/3 - 1

Now we can write our system as:

Three-digit addition and subtraction with regrouping involves adding or subtracting numbers with three digits (numbers between 100 and 999) while carrying or borrowing values from one place value to another.

Addition is a basic arithmetic operation that involves combining two or more numbers or quantities to find the total amount or sum. It is often denoted by the symbol "+". For example, if we add 2 and 3, we get a sum of 5.

For example, let's say we want to add 357 and 468:

In this example, we first add the ones place (7 + 8 = 15), which gives us a sum of 5 and carry-over of 1. We then add the tens place (5 + 6 = 11) and add the carry-over from the ones place, which gives us a sum of 2 and carry-over of 1. Finally, we add the hundreds place (3 + 4 = 7) and add the carry-over from the tens place, which gives us a final sum of 825.

R(x) = -30(x - 6)² + 320

This equation for the revenue is a quadratic equation model written in the form of completing the square;

This form appears like so:

f(x) = a(x + b)² + c

It is quite useful, especially for this type of question;

Firstly, if a is positive, the quadratic equation will be a u shaped graph when illustrated, if negative, it will be an n shaped graph;

What this means is if a is positive, the vertex of the graph is the lowest point, i.e. the minimum value of f(x), and if a is negative, the vertex will be the highest point, i.e. the maximum value of f(x);

Secondly, the coordinates of the vertex will be:

(-b, c)

So, with regards to the question:

We have -30 in the position of a, the curve is therefore n shaped and the vertex is the highest point (known as the local maximum);

And in place of b and c, we have -6 and 320, so the coordinates of this local maximum are:

(6, 320)

We interpret this like so:

320 is the highest possible value of R(x), which represents revenue, so $320 is the maximum revenue according to this model, and it is achieved when x = 6, i.e. when the price is increased by $0.90 (= 6 × $0.15);

Finally, to get the new ticket price, we add this to the original price to get $2.90.
