Java Generic 2D Linked List Problem

How to convert a 1D linked List into multiple linked lists with sequential values together?

//Example 1: [1,1,2,3,3] becomes [[1,1],[2],[3,3]]
//Example 1: [1,1,2,1,1,2,2,2,2] becomes [[1,1],[2],[1,1],[2,2,2,2]]
//Example 3: [1,2,3,4,5] becomes [[1],[2],[3],[4],[5]]

public <T> List<List<T>> convert2D(List<T> list) {

// Given a 1D, need to combine sequential values together.

Flip all 3 coins 10 times. Each flip place a tally mark next to the number of heads in the following table

For each of the tables on the previous side, make a frequency distribution and a relative distribution

10 Tosses

50 Tosses

100 Tosses

1. Draw a tree Diagram to represent the event of tossing three coins

2. What is the sample space for this event?                        

3. Using the random variable, X, that measures the number of heads when you toss three coins, write the theoretical probability distribution.

4. Write a few sentences that compare and contrast the relative frequencies between the three experiments. Why are they different or similar?

5. Write a few sentences that compare relative frequencies with the theoretical probabilities. Why would they be similar or different? What happens as the number of trials gets bigger?

The random variable X can take on the values 1, 2 and 3 and the random variable Y can take on the values 1, 3, and 4. The joint probability distribution of X and Y is given in the following table:

a. What value should go in the blank cell?

b. Describe in words and notation the event that has probability 0.2 in the table.

c. Calculate the marginal distribution of X and the marginal distribution of Y.

d. Are X and Y independent events? Show why or why not with calculations.

e. Calculate the conditional distribution of X given Y=1.

f. Calculate E(X) and E(Y).

g. Calculate V(X) and V(Y).

h. Calculate E(X|Y=1).

In a sample of families with 6 children each, the distribution of boys and girls is as shown in the following table:

Part A) Calculate the chi-square value to test the hypothesis of a boy-to-girl ratio of 1:1. (Express your answer using three decimal places)

Part B) Are the numbers of boys to girls in these families consistent with the expected 1:1 ratio? Yes or No

Part C) Calculate the chi-square value to test the hypothesis of binominal distribution in six-child families. (Express your answer using three decimal places)

Part D) Is the distribution of the numbers of boys and girls in the families consistent with the expectations of binomial probability? Yes or No

It's Java; the code should be the same as the output sample below; please, thank you.

Note: create a single-file solution that has multiple class definitions. Also, note that the static main() method should be a member of the Vehicle class.

Create a class called Vehicle that has the manufacturers name (type String), number of cylinders in the engine (type int), and owner (type Person given next). Then, create a class called Truck that is derived from Vehicle and has the following additional properties: the load capacity in tons (type double since it may contain a fractional part) and towing capacity in pounds (type int). Be sure your class has a reasonable complement of constructors, accessor and mutator methods, and suitably defined equals and toString methods. Write a program to test all your methods (see sample run).

The definition of the class Person follows. Completing the definitions of the methods is part of this programming project.

class Person{
private String name;
public Person()
{...}
public Person(String theName)
{...}
public Person(Person theObject)
{...}
public String getName()
{...}
public void setName(String theName)
{...}
public String toString()
{...}
public boolean equals(Object other)
{...}
}

Which value of x, with −4 ≤ x ≤ 4, corresponds to the global (absolute) maximum of the functions f(x) = x 2 (3x 2 − 4x − 36) + c, where c is some given real number?

(a) −2 (b) 2 (c) 3 (d) 0 (e) None of the above.

14. Find f(x) by solving the initial value problem. f 0 (x) = e x − 2x; f (0) = 2

(a) f (x) = e x − x 2 (b) f (x) = e x − x 2 + 1 (c) f (x) = e x − x 2 + 2 (d) f (x) = e x − x 2 + C (e) None of the above.

18. Let f(x, y) = 1 + x + y + x 2 + axy + y 2 be a function of two variables. Suppose it is always true that ∂f /∂x = ∂f /∂y . What is the value of a?

(a) Any value of a is possible since mixed partial derivatives are equal. (b) 0 (c) 2 (d) 1 (e) There is no such value of a since the partial derivatives must be different.

Please provide the correct solution for each problem for a thumbs up. thank you!

The owner of a moving company typically has his most experienced manager predict the total number of labor hours that will be required to complete an upcoming move. This approach has proved useful in the past, but the owner has the business objective of developing a more accurate method of predicting labor hours. In a preliminary effort to provide a more accurate method, the owner has decided to use the number of cubic feet moved as the independent variable and has collected data for 36 moves in which the origin and destination were within the borough of Manhattan in New York City and in which the travel time was an insignificant portion of the hours worked.

A) Construct a scatter plot.

B) Assuming a linear relationship, use the least-squares method to determine the regression coefficients b₀ and b_1.

C) Interpret the meaning of the slope, b₁, in this problem.

D) Predict the mean labor hours for moving 500 cubic feet.

E) What should you tell the owner of the moving company about the relationship between cubic feet moved and labor hours?

Please show all work in detail.
