Problem 5 (16 points): Jack and Jill Smith have just retired and want to build a small cabin. For their weekends They have hired Susan Smith as the general contractor for the project, who has three workers to complete the project: Tom, Dick and Harry. Susan has negotiated a cost-plus contract with the Smiths whereby she will receive 15 percent profit beyond the cost of labor and materials. Daryl has estimated that the cost for materials, permits, etc., will total $50,000. This is one of several projects Daryl is managing, and other than occasionally helping out, her role is strictly limited to supervising. She has devised the hereunder master plan and assignments. Dick is the only skilled plumber in the group while Harry is the only skilled electrician. Tom is a general carpenter and can assist them with their work. Dick and Harry each get paid $300 a day while Tom gets paid $200 per day. All workers are scheduled to work 5 days/week throughout the project. 1) Draw a GANTT chart, also showing the people assigned (MS Project or manual) 2) Calculate the project direct cost estimate, including materials and direct labor. Show your cost calculations. 3) What is the price estimate of the project to the Smith's? Show your calculation..

There are three members: The application is by far the most complex system that you have attempted so far. It consists of eleven classes, two structs, one interface and two enums coupled in varying degrees of tightness. The Bank class is the main driver of the application. It has collection of Accounts and Person that is initialize appropriately in the static constructor. You will implement the entire system in Visual Studio. A short description of each type with their members is given below. You are advised to implement each type in the order that they are described. No method should have a Console.

Problem: Susan Sound predicts that students will learn most effectively with a constant background sound, as opposed to an unpredictable sound or no sound at all. She randomly divides twenty-four students into three groups of eight. All students study a passage of text for 30 minutes. Those in group 1 study with background sound at a constant volume in the background. Those in group 2 study with noise that changes volume periodically. Those in group 3 study with no sound at all. After studying, all students take a 10 point multiple choice test over the material. Their scores follow: Calculate the Between-Subject One-Way ANOVA, make sure you include all the steps and show your calculations. Determine if you need a post hoc analysis, if so, complete the post-hoc analysis Interpret the results of your statistical calculation.

How to Break the cycle of negative Thoughts

Col Mukteshwar Prasad

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

The Roman Empire A Historical Colossus.pdf

kaushalkr1407

The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence. The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth. Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration. The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority. Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages. Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
