American History Key Terms: From Colonization to the Constitution

Native Americans and Early European Colonization

  • Bering Strait: Ice Age land bridge between Siberia and Alaska; early migration route into North America (15,000+ years ago).
  • Cahokia: Large mound-building Native city near modern St. Louis (c. 600–1300); proof of sophisticated precolonial societies.
  • Reasons Europeans came to the “New World”: Wealth/resources, competition for empire, Asian trade routes, conversion, and religious refuge → distinct colonies and economies.
  • Christopher Columbus: Italian

Algorithms Q&A: MST, Knapsack, and Backtracking

Q1. State Minimum Cost Spanning Trees Problem. Discuss Prim’s Algorithm to Solve This Problem and State Its Running Time.

Minimum Cost Spanning Tree (MCST/MST): Given a connected, weighted, undirected graph G = (V, E), a spanning tree connects all vertices using exactly |V| − 1 edges and contains no cycle. An MST is a spanning tree having minimum total edge weight: Cost(T) = Σ w(e), e ∈ T.

Prim’s Algorithm: A greedy algorithm that starts from any vertex and repeatedly adds the minimum-weight

Advanced Statistical Modeling and Real-Time Stream Analytics

Regression Modeling: Linear and Multiple Regression

1. Definition

Regression modeling is a statistical technique used to study the relationship between a dependent variable and one or more independent variables. It is mainly used for prediction and estimating relationships between variables.

2. Simple Linear Regression

It uses one independent variable.

$$Y = \beta_0 + \beta_1X + \epsilon$$

where:

  • $Y$ = dependent variable
  • $X$ = independent variable
  • $\beta_0$ = intercept
  • $\beta_1$ = regression coefficient
  • $\
