What are the four rules of probability?
Space and AstronomyWhat are the 4 Laws of Probability? Addition rule: P(A or B) = P(A) + P(B) – P(A and B) Multiplication rule: P(A and B) = P(A) . P(B/A) The sum of the probabilities of all possible outcomes = 1. Complementary law: What are the four rules of probability in statistics? The Four Probability Rules
What did the Sputnik 1 discover?
Space and AstronomyTracking and studying Sputnik 1 from Earth provided scientists with valuable information. The density of the upper atmosphere could be deduced from its drag on the orbit, and the propagation of its radio signals gave data about the ionosphere. What was Sputnik 1 and why was it important? On October 4, 1957, the Soviet Union
What did Ellen Ochoa discover?
Space and AstronomyShe patented an optical system to detect defects in a repeating pattern and is a co-inventor on three patents for an optical inspection system, an optical object recognition method, and a method for noise removal in images. What is Ellen Ochoa doing now? Ochoa retired from the Johnson Space Center in 2018to become vice chair
Is cork fabric waterproof?
Space and AstronomyCork fabric is durable as leather and as versatile as fabric. This material is environmentally friendly, hypoallergenic, water resistant and stain resistant as well as easily cleaned and long lasting. Can cork fabric get wet? Cork fabric is environmentally friendly, hypoallergenic, water resistant and stain resistant. Note: Due to the natural characteristics of cork along
What is magnification physics?
Space and AstronomyWhat do you mean by magnification in physics? Magnification is the process of enlarging the apparent size, not physical size, of something. This enlargement is quantified by a calculated number also called “magnification”. When this number is less than one, it refers to a reduction in size, sometimes called minification or de-magnification. What is magnification
How do you describe the translation of a graph?
Space and AstronomyIf you move the graph left or right in the direction of the horizontal axis, without rotating it, you are “translating” the graph horizontally. Move the graph straight up or down in the direction of the vertical axis, and you are translating the graph vertically. How do you describe translation? A translation moves a shape
How are baskets measured?
Space and AstronomyHeight is always measured from the bottom of the basket to the top. Also, we typically provide only the outside dimensions of the baskets, unless otherwise specified. All dimensions are given at the longest, widest, or tallest points of the basket, but may or may not include the handle. How do you measure the size
Why do we use point slope form?
Space and AstronomyThe point-slope form of a linear equation is most useful for finding a point on a line when you know the slope and one other point on the line. It can also be used to find a point on the line when you know two other points. What is the point slope form used for?
Why are most large telescopes reflectors not refractors quizlet?
Space and AstronomyWhy are most large telescopes reflectors, not refractors? A. Reflectors do not suffer from chromatic aberration like refractors do. Why are most large telescopes are reflectors not refractors? The main reason that most professional research telescopes are reflectors is that: Large mirrors are easier to build than large lenses. Which design was a primary mirror
Is the sun made of stars?
Space and AstronomyThe Sun is a G-type main-sequence star that constitutes about 99.86% of the mass of the Solar System. The Sun has an absolute magnitude of +4.83, estimated to be brighter than about 85% of the stars in the Milky Way, most of which are red dwarfs. The Sun is a Population I, or heavy-element-rich, star.
