This problem involves a binomial distribution with n = 30 trials and a success probability of p = 0.45 (using a smartphone in meetings or classes).
The probability of exactly k successes in n trials is given by the binomial probability formula:
P(k successes) = (n choose k) * p^k * (1 - p)^(n - k)
where (n choose k) is the binomial coefficient, equal to n! / (k! * (n - k)!).
Substituting n = 30, p = 0.45, and k = 24, we have:
P(24 out of 30 use smartphones in meetings/classes) = (30 choose 24) * (0.45)^24 * (0.55)^6
Using a calculator or software, we can evaluate this probability as:
P(24 out of 30 use smartphones in meetings/classes) ≈ 0.005
Therefore, the probability of exactly 24 out of 30 adult smartphone users using their smartphones in meetings or classes, when randomly selected, is approximately 0.005 or 0.5%.
The sale price of a laptop is $505.44 after 35% discount and 8% additional tax. What was the original price of the laptop before discount and tax?
Answer:
The original price of the laptop before discount and tax was $718.46.
Explanation:
Let's work backwards from the sale price to find the original price:
1. First, we need to remove the effect of the additional 8% tax.
We can do this by dividing the sale price by 1.08 (100% + 8% = 108%) :
$505.44 / 1.08 = $467.00 (rounded to the nearest cent)
2. Now we need to remove the effect of the 35% discount. We can do this by dividing the price before discount by 0.65 (100% - 35% = 65%) :
$467.00 / 0.65 = $718.46 (rounded to the nearest cent)

Roger Williams was banished from the Massachusetts Bay Colony because he _____.
argued for the separation of church and state
no longer believed in God
refused to follow the Sabbath
was friendly to the Native Americans
Answer:
Explanation:
Roger Williams was banished from the Massachusetts Bay Colony because he argued for the separation of church and state. He believed that the government should not be involved in religious matters and that people should be free to worship as they please without interference from the state. This view was considered heretical by the Puritan leaders of the colony, who believed that the government had a duty to enforce religious orthodoxy. As a result, Williams was banished from the colony in 1635 and went on to found the colony of Rhode Island, which became known for its commitment to religious freedom and tolerance.
Construct an argument that is valid according to the pattern of modus
tollens and which has the following universal statement as its main premise: "All planets
orbit the sun.”
Answer:
Explanation:
Modus Tollens is a valid form of deductive reasoning that works by first assuming a conditional statement, and then using a negation of the consequent to prove that the antecedent must also be false.
Here's an example of an argument that is valid according to the pattern of modus tollens and uses the universal statement "All planets orbit the sun" as its main premise:
Premise 1: All planets orbit the sun.
Premise 2: Pluto does not orbit the sun.
Conclusion: Therefore, Pluto is not a planet.
In this argument, the main premise is the universal statement "All planets orbit the sun." The second premise is the negation of the consequent - that Pluto does not orbit the sun. By using modus tollens, we can logically conclude that the antecedent (that Pluto is a planet) must be false, and therefore, the conclusion is that Pluto is not a planet.
This argument is valid because it follows the structure of modus tollens, and the premises are both true. By starting with a universal statement, we can make a logical deduction based on a particular instance that contradicts the universal statement. In this case, the fact that Pluto does not orbit the sun contradicts the universal statement that all planets orbit the sun, and therefore, we can conclude that Pluto is not a planet.
1. Respond: Would you like to travel with Gulliver? Explain
2. (a) Support: In the final paragraph of "A Voyage to Brobdingnag," how does Swift use the King's reactions to express his own hopes for humankind? (b) Assess: Do you think these hopes are valid? Wh or why not?
I would be interested in exploring different parts of the world and experiencing different cultures.
The use of reactions by SwiftRegarding the second question, in the final paragraph of "A Voyage to Brobdingnag," Swift uses the King's reactions to express his hopes for humankind.
The King expresses his disgust at the corruption and greed of the human race, and his admiration for Gulliver's honesty and simplicity. Swift's hope is that by exposing the flaws and weaknesses of humanity, we may be able to recognize and correct them.
As for the validity of these hopes, it is subjective and open to interpretation.
While some may argue that Swift's critique of humanity is overly pessimistic, others may agree with his assessment and believe that we need to address the issues he highlights.
Ultimately, whether or not these hopes are valid depends on one's perspective and beliefs about human nature.
