The probability that a randomly selected marriage will last at least 20 years, given that the woman has a bachelor's degree, the probability cannot be calculated without the specific value for P(A|B).
Let's denote the event A as "the woman has a bachelor's degree" and event B as "the marriage lasts at least 20 years."
According to the research agency, P(A) = 0.25, which represents the probability that a randomly selected marriage involves a woman with a bachelor's degree.
The census report states that P(A') = 0.36, where A' represents the complement of event A, i.e., the probability that a woman does not have a bachelor's degree.
The census report also provides the probability of event B, P(B) = 0.53, which represents the probability that a randomly selected marriage lasts at least 20 years.
We need to find P(B|A), the probability that a marriage lasts at least 20 years given that the woman has a bachelor's degree.
To calculate P(B|A), we use the formula for conditional probability:
P(B|A) = P(A ∩ B) / P(A)
From the given information, we know that P(A ∩ B), the probability that a woman has a bachelor's degree and the marriage lasts at least 20 years, is not provided directly.
However, we can use the concept of joint probability and rearrange the formula as follows:
P(A ∩ B) = P(B) * P(A|B)
P(A|B) represents the probability that the woman has a bachelor's degree given that the marriage lasts at least 20 years.
Since P(A|B) is not given explicitly, we cannot determine it directly from the information provided.
Therefore, without the specific value for P(A|B), we cannot calculate the probability that a randomly selected marriage will last at least 20 years, given that the woman has a bachelor's degree.

Is it true that The earliest evidence of accounting is the double-entry system used in the thirteenth century?
Answer:
No
Explanation:
No, it is not true. While the double-entry system is an important and widely used method in accounting, there is evidence of accounting practices dating back to ancient civilizations such as the Babylonians and Egyptians. The ancient Greeks and Romans also had various forms of accounting and record-keeping. However, the double-entry system as we know it today was first described by Italian mathematician Luca Pacioli in his book "Summa de Arithmetica, Geometria, Proportioni et Proportionalità" in the 15th century.

How do ocean currents effect the air temperature for Luderitz and Florianopolis?
Answer:
Ocean currents can have a significant effect on air temperature in coastal areas like Luderitz and Florianopolis.
Luderitz, located on the Atlantic coast of Namibia, is influenced by the cold Benguela Current which flows northward along the coast from Antarctica. This current cools the air above it, resulting in lower air temperatures in Luderitz compared to other locations at a similar latitude.
Florianopolis, on the other hand, is located on the Atlantic coast of Brazil and is influenced by the warm Brazil Current, which flows southward along the coast from the equator. This current warms the air above it, resulting in higher air temperatures in Florianopolis compared to other locations at a similar latitude.
Therefore, in both cases, the ocean currents play a significant role in determining the air temperature of the coastal areas.

When a plant is not strong enough to support its own weight, what is most likely the problem? O A. The plant is producing too many polysaccharides. B. The plant is not producing enough cellulose. C. The plant needs more monosaccharides to add strength. D. The plant does not have enough starch. ✔ Correct
(D) The plant is not producing enough cellulose
Yes, you are correct. When a plant is not strong enough to support its own weight, the most likely problem is that the plant is not producing enough cellulose. Cellulose is a complex carbohydrate that provides structural support to plant cell walls. It forms strong fibers that help plants maintain their shape and rigidity. If a plant does not produce enough cellulose, its cell walls may be weak, leading to a lack of structural support and an inability to withstand the weight of the plant.[tex][/tex]

The newly elected president need to decide the remaining eight spots available for cabinet here she is appointing there are 12 eligible candidate for this position where rink matters how many different ways can the member of the cabinet be appointed
Answer: There are 495 different ways the members of the cabinet can be appointed.
Explanation:
nCr+n! / (r! * (n-r)!)
Where n is the total number of items, and r is the number of items to choose.
In this case, there are 12 eligible candidates for 8 spots. So, we need to find the humber of ways to choose 8 candidates from 12, which is:
12C8 = 12!/ (8! * (12-8)!)+495

2018 poll of 2232 randomly selected U.S. adults found that 40.86% planned to watch at least a "fair amount" of a particular sporting event in 2018.
In 2014, 47% of U.S, adults reported planning to watch at least a "fair amount."
a. Does this sample give evidence that the proportion of U.S. adults who planned to watch the 2018 sporting event was less than the proportion who planned to do so in 2014? Use a 0.05 significance level.
b. After conducting the hypothesis test, a further question one might ask is what proportion of all U.S. adults planned to watch at least a "fair amount" of the sporting event in 2018. Use the sample data to construct a 90% confidence interval for the population proportion. How does your confidence interval support your hypothesis test conclusion?
a. Let p
1
be the proportion of U.S. adults who planned to watch at least a "fair amount" of the 2018 sporting event and p
2
be the proportion of U.S. adults who planned to do so in 2014. We want to test the following hypotheses:

We will use a significance level of α=0.05.
Our sample size is n=2232 and our sample proportion is

SE(

p(1−p)

0.4086−0.47
=−6.38
Our p-value is P(z<−6.38)=0.000000000002.
Since our p-value is less than our significance level of α=0.05, we reject the null hypothesis. There is evidence to suggest that the proportion of U.S. adults who planned to watch the 2018 sporting event was less than the proportion who planned to do so in 2014.
b. A 90% confidence interval for the population proportion is:

CI=(0.4086−1.645⋅0.0097,0.4086+1.645⋅0.0097)
CI=(0.4002,0.4170)
We are 90% confident that the true proportion of U.S. adults who planned to watch at least a "fair amount" of the 2018 sporting event is between 0.4002 and 0.4170.
Our confidence interval does not include 0.47, the proportion of U.S. adults who planned to watch at least a "fair amount" of the sporting event in 2014. This supports our hypothesis test conclusion that the proportion of U.S. adults who planned to watch the 2018 sporting event was less than the proportion who planned to do so in 2014.
Before the radio and telephone were invented, some groups used patterns of drumbeats to send information to one another.
Which statement ,begin emphasis,best,end emphasis, explains how the patterns of drumbeats transferred information from one group to another?
Answer options with 4 options
A.
The different shapes of the drums produced different sounds.
B.
The pattern of drumbeats represented different words or phrases.
C.
The groups used different drums during different times of the year.
D.
The drumbeats were so loud that they could be heard from great distances.
The statement that best explains how patterns of drumbeats transferred information from one group to another is option B: "The pattern of drumbeats represented different words or phrases."
Groups that used drumbeats to communicate developed complex systems of rhythms and patterns that could convey specific meanings, much like a language. Different rhythms and patterns were associated with different words, phrases, or messages.
For example, a certain pattern of beats might represent a warning of danger, while another pattern might indicate the arrival of an important visitor. By varying the rhythm and duration of the beats, and by using different combinations of beats, the drummers could convey a wide range of meanings and messages.
Drum communication was particularly useful for groups that lived in areas with rugged terrain or dense forests, where it was difficult to communicate over long distances using spoken language.
The sound of the drums could carry for miles and was easily distinguishable from other sounds in the environment. In addition, because the drummers could use a code that was known only to their group, they could communicate privately without fear of interception or misinterpretation by outsiders.
In conclusion, the patterns of drumbeats used by certain groups to send information to one another represented different words or phrases. These rhythms and patterns allowed the drummers to convey a wide range of messages over long distances and in difficult terrain.
