Assignment A

1. Electrical Unit Failure Analysis

An electrical unit consists of four components, each subject to failure. We observe this unit at a specified time to determine which components are working and which have failed. What is the sample space associated with this random experiment?

Let: 7TVxAAAAMklEQVQYV2NgIAVwMwoKMQlyMzIASQEg denote working, and 7TVxAAAAOElEQVQYV2NgQAdCrExAIVE2fm4gJcgO denote failed.

The sample space is:

r0FVpCrlQq1hbtYj4GRDuBWRUyNYkTTre+ULPpX+

2. Set Operations

Suppose the sample space is: w8MgooHMhmQAAAAASUVORK5CYII= . Let: Ah3KH1ZdVC6IAAAAAElFTkSuQmCC , P7QsOtpxon0ScHGICU69ueneJYv4B4EfzfMfJs+B , and GVqf0R6ASYXx9u0HKKzAAAAABJRU5ErkJggg== .

Determine the sets: rJ4EMhaCNY2UvgAAAABJRU5ErkJggg==

Here: 1D3L2AXFUIWU9OyTQYAAAAASUVORK5CYII=

Thus, s1c+AZFgH4yljD1VAAAAAElFTkSuQmCC

So, 5L3W4yP8V+QmWmTt3MOHHfAAAAABJRU5ErkJggg=

Variables, Hypotheses, Measurement, and Research Purposes

Variables and Hypotheses

An independent variable is thought to influence, affect, or cause variation in another variable. A dependent variable is thought to depend upon or be caused by variation in an independent variable.

Antecedent Variable: An independent variable that precedes other independent variables in time. It could affect the independent variable and alter its relationship to the dependent variable.

Intervening Variable: If the relation between X and Y is not spurious, then the intervening

Circumference, Ellipse, Parabola, and Hyperbola

Properties of the Circumference

The circumference is generated by the intersection of a cylinder or a straight circular cone with a plane. Geometrically, the circumference has several elements, such as:

  • Center: A fixed point equidistant to all points of the circumference.
  • Radius: The distance of the segment that joins the center of the circumference to any of its points.
  • Chord: The segment that joins any two points of the circumference.
  • Diameter: The chord that passes through the center and has the maximum
