For this question, you need to implement a simple linear regression from scratch without using a library. The linear equation that you need to use for this exercise is y=50x+22, which you will use to generate some synthetic data with random variation to make the problem interesting.

Lets discuss more in detail.

To begin, you need to randomly select 20 x values between 0 and 100 using a uniform distribution. To do this, you can use a for loop to iterate through the range of 0 to 100 and randomly select 20 x values.

Once you have your x values, you can then use the linear equation of y=50x+22 to calculate the corresponding y values. Finally, you can use these x and y values to create a linear regression and check if it rounds to the original equation.

Grading criteria: The result of your linear regression should round to the original equation. It is not expected to be perfect.

You can find more detailed steps on how to solve this problem in the sample notebook that will be going over in class. This should get you 80% through problem 1.

The method computes the employee's wage, stores it in the wage array, and returns it. The fixed wage is the amount of money each employee is paid per day, and the per item wage is the amount of money each employee is paid per item sold.

To receive full credit, the solution must call the computebonusthreshold appropriately.

public void compute wages(double fixed wage, double peritemwage) {

for (int i = 0; i < wages.length; i++) {

wages[i] = fixedwage + peritemwage * itemssold[i];

if (itemssold[i] >= computebonusthreshold()) {

wages[i] += bonus;

}

}}}

The above code performs the following operations: The wages array is declared in the method's signature, and the values are updated using a loop from 0 to the length of the wages array. The current value of wages is calculated by adding fixed wage to peritem wage times the current value of items sold. The wage of the employee is calculated using this formula. Finally, if the current value of items sold is greater than or equal to the computebonusthreshold, the value of wages is increased by bonus. The method computes the employee's wage, stores it in the wage array, and returns it. The fixed wage is the amount of money each employee is paid per day, and the per item wage is the amount of money each employee is paid per item sold.

The best explanation for why a binary search should not be used to search for an item in the list [-4, -1, 1, 5, 2, 10, 10, 15, 30] is that the elements of the list are not sorted. So, the correct option is (B).

A binary search algorithm is an algorithm that requires that the list be sorted in order to work. It works by splitting the sorted list into two parts and determining which part of the list contains the item that is being searched for. The list [-4, -1, 1, 5, 2, 10, 10, 15, 30] is not sorted, and as such, a binary search cannot be used to search for an item in the list.

A binary search algorithm is very efficient since it eliminates a large portion of the search area with each iteration. However, the list must first be sorted. Otherwise, the algorithm would not work correctly.

Production designers are an essential part of film and television production, responsible for the visual design of the project. However, their role can vary greatly between small and large budget productions.

On a small budget production, the production designer may be required to wear multiple hats, such as also serving as the art director or set decorator. They may need to work with limited resources and tight schedules, requiring them to be creative and resourceful in their designs. For example, in the low-budget film "Moonlight" (2016), production designer Hannah Beachler had a modest budget to work with and had to rely on practical locations, such as abandoned buildings and public housing projects, to create the film's setting.

On a large budget production, the production designer has more resources and personnel to work with, allowing them to create more elaborate and detailed sets and environments. They may also work closely with a team of art directors, set decorators, and visual effects artists to bring their vision to life. For example, in the big-budget film "Avatar" (2009), production designer Rick Carter and his team spent years developing the film's alien world of Pandora, using a combination of practical and digital effects to create the immersive environment.

In both cases, the production designer is responsible for creating a visual world that supports the story and enhances the audience's experience. However, the differences in budget and resources can greatly impact the scope and complexity of their designs
