A box in a certain supply room contains three 40-w lightbulbs, five 60-w bulbs, and seven 75-w bulbs. suppose that three bulbs are randomly selected. (round your answers to four decimal places.) (d) suppose now that bulbs are to be selected one by one until a 75-w bulb is found. what is the probability that it is necessary to examine at least six bulbs?
Answers
Answer:
0.0186
Explanation:
Given that there are 8 bulbs we don't want (3+5=8), and 7 bulbs we do want, there are 15 bulbs total.
If we are selecting bulbs one at a time, and we're looking for the probability that we don't find a bulb until at least the sixth try, we didn't find the right bulb on the first 5 tries. On the 6th try, we might have found the right bulb, or maybe we didn't and needed more tries, but we know that we must have missed on the first 5 tries.
So, we want the following probability:
\(P({1^{st}}_{\text{wrong}})*P({2^{nd}}_{\text{wrong}})*P({3^{rd}}_{\text{wrong}})*P({4^{th}}_{\text{wrong}})*P({5^{th}}_{\text{wrong}})*P({6^{th}}_{\text{right or wrong}})\)
At any point, the probability of choosing the wrong bulb is \(\frac{\text{\# wrong bulbs left}}{\text{\# bulbs left}}\)
Also, at any point, the probability of choosing a right or a wrong bulb is \(\frac{\text{\# bulbs left}}{\text{\# bulbs left}}\) which is equivalent to 1 . If you choose a bulb, you either chose a right one, or a wrong one, there's no other choice.
So, the probability we're looking for is as follows:
\(P({1^{st}}_{\text{wrong}})*P({2^{nd}}_{\text{wrong}})*P({3^{rd}}_{\text{wrong}})*P({4^{th}}_{\text{wrong}})*P({5^{th}}_{\text{wrong}})*P({6^{th}}_{\text{right or wrong}})\)\(\frac{8}{15}*\frac{7}{14}*\frac{6}{13}*\frac{5}{12}*\frac{4}{11}*\frac{10}{10}\)
0.0186480186
So, there is a 1.8648% chance of picking the correct bulb on the 6th try of later. In terms of probability, the probability (to 4 decimal places) is 0.0186

Can Pluto actually be the next Earth? If it wasn't so cold?
Answers
Note that even if Pluto was not cold, it lacks the essential conditions necessary for it to become the next Earth.
How is this so?Pluto cannot be the next Earth, even if it wasn't cold. There are several reasons for this:
1. Size and Composition - Pluto is much smaller than Earth and is composed primarily of rock and ice, whereas Earth has a diverse composition and a solid surface suitable for life.
2. Atmosphere - Pluto has a thin and tenuous atmosphere consisting mostly of nitrogen and methane, which is not conducive to supporting life as we know it.
3. Distance and Environment - Pluto's distance from the Sun and extreme cold temperatures make it inhospitable for sustaining life as we know it.
Therefore, even if Pluto was not cold, it lacks the essential conditions necessary for it to become the next Earth.

African states arise as a consequence of ties between the Asians and Europeans.
This same introduction of Islam across trading forums linked towards other nations increased Africa's variety and community sovereignty. States have always been allowed to form because there was no centralized power. Enslavement, as well as authoritarian norms, shaped the formation of the nation. Trade enabled Ghana and Mali countries to thrive, although a particular ideology emerged throughout Ethiopia as well as changed the people who lived here anyway.

assertion-some organisim live together and share both shelter and nutrient .reason- the organisim that live together are called lichens
Answers
The assertion that some organisms live together and share both shelter and nutrients is correct. Lichens are a prime example of such organisms.
Lichens are a unique symbiotic relationship between a fungus and an alga or cyanobacterium.
The fungus provides the shelter and protection by forming a structure or thallus, which acts as a home for the alga or cyanobacterium. In return, the alga or cyanobacterium provides nutrients through photosynthesis.
This mutualistic relationship allows both organisms to benefit. The fungus benefits from the nutrients produced by the photosynthetic partner, which helps it thrive in nutrient-poor environments.
Therefore, the organisms that live together in this symbiotic relationship are indeed called lichens.

Explain how the process of globalization contributed to the diffusion of sugarcane from its hearth of domestication.
Answers
The process of globalization has played a significant role in the diffusion of sugarcane from its hearth of domestication. Sugarcane is believed to have originated in Southeast Asia, and from there, it spread to other parts of the world through various channels, including trade, migration, and colonialism. Globalization, in its modern form, has accelerated the diffusion of sugarcane to different parts of the world, leading to its widespread cultivation and consumption.
One of the primary drivers of the diffusion of sugarcane was the global trade network that emerged in the 16th century. The European powers established trade routes to Asia, Africa, and the Americas, and in the process, they introduced sugarcane to different parts of the world. The Portuguese, for example, introduced sugarcane to Brazil, which would later become the largest producer of sugarcane in the world. The Spanish, on the other hand, introduced sugarcane to the Caribbean, which would become another major sugarcane-producing region.
Another factor that contributed to the diffusion of sugarcane was the movement of people. Globalization facilitated the movement of people from one part of the world to another, and in the process, they brought with them their cultural practices, including agriculture. The Indian indentured laborers, for example, were brought to the Caribbean in the 19th century to work on sugarcane plantations. They brought with them their knowledge of sugarcane cultivation and processing, which contributed to the growth of the industry in the region.
Finally, colonialism played a significant role in the diffusion of sugarcane. The European powers established colonies in different parts of the world and used their resources to cultivate cash crops, including sugarcane. The British, for example, established sugarcane plantations in India, which would become another major producer of sugarcane in the world. Similarly, the French established sugarcane plantations in Mauritius, which would become a major producer of refined sugar.
In conclusion, the process of globalization has contributed significantly to the diffusion of sugarcane from its hearth of domestication. The global trade network, movement of people, and colonialism have all played a role in the spread of sugarcane to different parts of the world. Today, sugarcane is one of the most widely cultivated and consumed crops in the world, with significant economic and cultural significance.

Answers
The pressure altitude at an airport that is 1,386 feet MSL with an altimeter setting of 29.97 is A. 1,341 feet MSL.
How to calculate the pressure altitude?It should be noted that in order to determine the pressure altitude at an airport, you need to know the actual altitude of the airport above mean sea level (MSL) and the altimeter setting. Also, the altimeter setting simply had to do with the current pressure at a reference altitude, usually at sea level, as reported by a local weather station.
If the actual altitude of the airport is 1,386 feet MSL and the altimeter setting is 29.97, the pressure altitude can be calculated using the following formula:
Pressure altitude = Altitude MSL + (29.92 - Altimeter Setting) x 1,000 feet
Then, week slot in the values from the question into the formula. This goes thus:
Pressure altitude = 1,386 + (29.92 - 29.97) x 1,000 feet
Solving for the pressure altitude, we will then get:
Pressure altitude = 1,386 + (-0.05) x 1,000 feet
Pressure altitude = 1,386 + (-50) feet
Pressure altitude = 1,336 feet MSL
In conclusion, the pressure altitude at the airport is 1,336 feet MSL. Therefore, the correct option based on the information is A.

The test of his belief for statistical significance will be a: one-tailed right test. The correct option is C.
We can conduct a hypothesis test to verify the administrator's assertion that seniors' second-semester GPAs are lower than seniors' first-semester GPAs.
According to the null hypothesis (H0), there is no discernible difference between the two means.
H0: u1 - u2 = 0
The contrary hypothesis (Ha) would assert that the second semester's GPA is, in fact, lower than the first semester's GPA:
Ha: u1 - u2 > 0
We are using a one-tailed right test because the administrator thinks the second semester's GPA is lower.

“The seriousness of play is shown in the standard of effort and achievement that it holds up. The strictest schoolmaster of the old nose-to-the-grindstone school never secured the whole-hearted effort that is seen on the ball field every afternoon. A small boy throws a ball so as to curve in a way which a few years ago was thought to be impossible, another hits it with a round stick, while a third urchin in the distance runs as fast as he can and catches it. When you consider how little of the course of the ball the third boy saw before he started to run, and take into account—or better still experience—the other difficulties involved in the whole performance, you will realize that such feats, though seen every day on every ball field, are somewhat remarkable. At least things equally difficult done by boys in their arithmetic lessons would be considered so.”
