What is meant by statistical independence?
Space and AstronomyTwo events are independent, statistically independent, or stochastically independent if, informally speaking, the occurrence of one does not affect the probability of occurrence of the other (equivalently, does not affect the odds). Why is statistical independence important? The assumption of independence is a foundation for many statistical tests. The assumption of independence is used for
What is the sun made out of NASA?
Space and AstronomyStructure. The Sun is a huge ball of hydrogen and helium held together by its own gravity. What is the Sun in space made of? The sun is a big ball of gas and plasma, but what is the sun made of exactly? Most of the gas — around 92% — is hydrogen, according to
How do you measure the diameter of a pole?
Space and AstronomyStep 1 – Measure the circumference of the post (distance around the post). Step 2 – Take that measurement and divide it by pi (3.14) to determine the post diameter. What is the diameter at the pole? Equatorial vs Polar Diameter: Because of this, the diameter of the Earth at the equator is about 43
What holds the sun together?
Space and AstronomyStructure. The Sun is a huge ball of hydrogen and helium held together by its own gravity. How does the Sun stay in one place? The Sun spins or rotates on its axis in the same direction as Earth (counterclockwise, when looking down from the north pole). Because it is a gas, it does not
What does Blue shifting mean?
Space and AstronomyWhat does Blue shifting tell us? When an object is moving away from us, the light from the object is known as redshift, and when an object is moving towards us, the light from the object is known as blueshift. Astronomers use redshift and blueshift to deduce how far an object is away from Earth,
Can you have a slant and horizontal asymptote?
Space and AstronomyA graph can have both a vertical and a slant asymptote, but it CANNOT have both a horizontal and slant asymptote. You draw a slant asymptote on the graph by putting a dashed horizontal (left and right) line going through y = mx + b. Can horizontal Asymptotes be slanted? A slant asymptote, just like
What are pieces of rock that strike the surface of a moon or planet?
Space and AstronomyThe pieces that do strike Earth’s surface are called meteorites. Both meteors and meteorites can become natural hazards to the communities they impact. Very large meteors called bolides may explode in the atmosphere with the force of 500 kilotons of TNT. What do you call a rock from space that strikes Earth’s surface? This glowing
Is the range the output?
Space and AstronomyThe domain is the input, the independent value—it’s what goes into a function. The range is the output, the dependent value—it’s what comes out. Is range and output the same? The range is the set of outputs of y-coordinates. When both the independent quantity (input) and the dependent quantity (output) are real numbers, a function
How do you name a segment?
Space and AstronomyA segment is named by its two endpoints, for example, ¯AB . A ray is a part of a line that has one endpoint and goes on infinitely in only one direction. You cannot measure the length of a ray. A ray is named using its endpoint first, and then any other point on the
How do you prove congruent complements Theorem?
Space and AstronomyIf two angles are complementary to the same angle (or to congruent angles), then they are congruent. If ∠4 and ∠5 are complementary and ∠6 and ∠5 are complementary, then ∠4 ≅ ∠6. How do you prove that angles are congruent to each other? Two angles are congruent if they have the same measure. You
