What is the multiplication rule for independent events?
Space and AstronomyThe specific multiplication rule, P(A and B) = P(A) * P(B), is only valid if the two events are independent. In other words, it only works if one event does not change the probability of the other event. What is the rule for independent events? Events A and B are independent if the equation P(A∩B)
How do you get calla lilies to bloom again?
Space and AstronomyPlace it in a cool (not cold) dark place for two months. After this, bring it back out into the light and resume watering it. The foliage will regrow and you calla lily plant will start to bloom shortly thereafter. How do you keep calla lilies blooming? Here are a few tips for caring for
What are comets similar to?
Space and AstronomyExploring comets Although ICE had no cameras, it detected water and carbon monoxide, confirming the theory that comets are similar to dirty snowballs. Are comets similar to asteroids? Although both asteroids and comets were formed in the early days of our solar system’s formation, asteroids are huge rocky objects that are mostly found in the
What is a rectangle model for multiplication?
Space and AstronomyIn mathematics, an area model is a rectangular diagram or model used for multiplication and division problems, in which the factors or the quotient and divisor define the length and width of the rectangle. What is rectangle method multiplication? Video quote: The first step in solving using rectangular sections is by simply drawing a rectangle.
How does the Gregorian telescope work?
Space and AstronomyThe Gregorian telescope consists of two concave mirrors: the primary mirror (a concave paraboloid) collects the light and brings it to a focus before the secondary mirror (a concave ellipsoid), where it is reflected back through a hole in the centre of the primary, and thence out the bottom end of the instrument, where …
How many stars can be seen in the night sky by an observer at any one time?
Space and AstronomyOther estimates place the number of stars visible to the eye alone – surrounding the entire Earth – at more like 5,000. At any given time, half of Earth is in daylight. So only half the estimated number – say, between 5,000 and 2,500 stars – would be visible from Earth’s night side. How many
Can you look at an annular eclipse?
Space and AstronomyThere is no danger to the eye in looking directly at a total solar eclipse. However; looking directly at the smallest part of a partial eclipse, including any annular eclipse, is very dangerous and can result in retinal damage. Can you observe an annular eclipse of the moon? There are no annular lunar eclipses because
Is a glide reflection Isometry?
Space and AstronomyA glide-reflection is an isometry that is the product of a reflection and a translation in the direction of the axis of the reflection. Theorem 4.1. Every isometry of the plane, other than the identity, is either a translation, a rotation, a reflection, or a glide-reflection. Is a reflection an isometry? A reflection in a
What is linear combination and span?
Space and AstronomyA linear combination is a sum of the scalar multiples of the elements in a basis set. The span of the basis set is the full list of linear combinations that can be created from the elements of that basis set multiplied by a set of scalars. What is a span in linear? The span
What is the day temperature on Mars?
Space and AstronomyWhy Mars is so cold In winter, near the poles, temperatures can get down to minus 195 degrees F (minus 125 degrees C). A summer day on Mars may get up to 70 degrees F (20 degrees C) near the equator, but at night the temperature can plummet to about minus 100 degrees F (minus
