Explain the addition rule of Pascal’s Triangle in your own words in terms of the path coding scheme you worked with in this assignment.
Suppose you want to create a path between each number on Pascal’s Triangle. For this exercise, suppose the only moves allowed are to go down one row either to the left or to the right. We will code the path by using bit strings. In particular, a 0 will be used for each move downward […]
Calculate the kinetic energy of the two particles before and after collision.
Deduce the final equation by using the cos and sin theta Considerer the collision between a moving particle of mass M1 and an initially stationary particle of mass M2, assume collision occurs at an angle θ defined by the initial trajectory of M1 and the line joining the mass centers at contact. 1- Calculate the […]

State these explicitly in a table and provide a justification with one sentence-Define “tall parents”
Stata about the Econometrics Part 1: Analysis with Galton’s original data set Galton’s work on children and parents’ height was published in: Galton, F. (1886): “Regression towards mediocrity in hereditary stature”, Journal of the Anthropological Institute, 15: 246-63. In this first part of the project you are asked to reconstruct the original data from this […]
Explain how it was decided whether to itemize deductions or use the standard deduction.
Compute the gross income, adjusted gross income, and taxable income in the following situation. Use the exemptions and deductions in the table to the right. Explain how it was decided whether to itemize deductions or use the standard deduction. A woman is single and earned wages of $61,100. She received $260 in interest from a […]
Explain why we need to find multiplicative inverses modulo a number.
1.1 Inverses Explain why we need to find multiplicative inverses modulo a number. Find 122-1mod 761, if possible, without using an inverse calculator. If not possible, explain what goes wrong in your calculations. If it is possible, make sure you show all of your calculations and justification. Find 122-1mod 760, if possible, without using an […]
What additional information would be valuable to help draw a more certain conclusion?
Outline of Material to Present This assignment is broken down into four parts: Collection of Data, Organization of Data, Analysis of Data, and Conclusion/Recommendations. Each part has a subset of questions and issues you must address. ensure that your report includes a section for each of the 4 Parts listed below, and that each part […]
Solve the following quadratic equation by the factorisation method:
Algebra Solve the following quadratic equation by the factorisation method: x ^ 2 + 2√2x – 6 = 0
at skills will you apply to know whether you can trust the result?
. To study about the correlation between height and shoe size, you need to collect a sample of nine (9) people using a Systematic Sampling method. What is the population of people? Where and how are you going to collect your sample? Does your sample accurately represent your population? Why or why not? Collect the […]
