The passenger's velocity relative to the road is calculated by subtracting the passenger's speed from the bus's speed since they are moving in opposite directions. Thus, the passenger's velocity relative to the road is 12 km/h south.

The passenger's velocity relative to the bus is 3.0 km/h towards the back of the bus. However, given that the bus is moving south at 15 km/h, the passenger's velocity relative to the road is actually the bus's speed subtracted by the passenger's speed (as they're moving in opposite directions). Therefore, the passenger's velocity relative to the road is 15 km/h - 3.0 km/h = 12 km/h towards the south or simply 12 km/h south.

Answer:

B

Step-by-step explanation:

The question deals with a simple random sampling method for a statistics class, discussing various techniques such as proportionate random sampling, systematic sampling, and the importance of each individual having an equal chance of being selected to ensure a representative sample.

The student's question involves selecting a simple random sample of 30 students from a population of 250 students in a large statistics class, using the sampling frame of students present next Monday. The concept described relates to sampling methods within the field of statistics, used to infer characteristics of a larger population. One method mentioned is proportionate random sampling, where a sample is obtained from each class based on the proportion of students in the college (e.g., if 30% of students are freshmen, then 30% of the sample would come from the freshman class). Another method is systematic sampling, where a starting point is chosen using a random number generator and then every nth student is selected (e.g., every 50th student). An important characteristic of a good sample is that every individual in the population should have an equal chance of being included, which is a hallmark of both random and systematic sampling methods. Finally, stratification, such as by class standing or other demographic factors, ensures that the sample is representative of the population under study, which might involve working with local schools to select a random sample of students from various backgrounds.

The answer is: B.) 9(4 + 7)

The solution to the equality statement "twice a number increased by 4 is at least 10 more than a number" is x ≥ 6.

Given the parameter:

Twice a number increased by 4 is at least 10 more than a number.

First, we convert the statement to an inequality;

Let x represent the unknown number:

Twice a number increased by 4 ⇒ 2x + 4

Is at least ⇒ ≥

10 more than a number ⇒ x + 10

Let's combine the inequality:

2x + 4 ≥ x + 10

Now, we solve for x:

2x - x + 4 ≥ x - x + 10

2x - x + 4 - 4 ≥ 10 - 4

x ≥ 6

Therefore, the solution to the inequality is x ≥ 6.

Final answer:

Julio started with the number 20. Cubing a number and then taking the cube root of the result returns the original number.

Explanation:

If Julio ends with 20 after cubing a number and then taking the cube root of the result, it means that the original number he started with must be 20. This is because the operations of cubing a number and then taking the cube root are inverse operations. Performing these operations one after the other will return the original value. So, the cube root of a number cubed is the number itself.

For example, if Julio starts with the number x, cubes it to get x3, and then takes the cube root of x3, he will end up with the original number x. In this case, since he ends up with 20, this means x equals 20.

41 passengers on the Mayflower were able to make an agreement for all through a democratic process, likely involving discussions, debates, and voting.

The key to understanding how 41 passengers could make an agreement for all lies in the democratic decision-making process. On the Mayflower, it's reasonable to assume that the passengers engaged in discussions and debates to reach a consensus on important matters. In a democratic setting, decisions are often made through a majority vote. If a decision required agreement from the majority of passengers, and there were 101 passengers in total, then 41 individuals would be sufficient to constitute a majority.

Democracy operates on the principle of majority rule, meaning that decisions are determined by the preferences of more than half of the participants. In this case, if 41 passengers were in agreement, they would have constituted a majority, allowing them to make decisions on behalf of the entire group. This form of decision-making is practical for large groups, as it ensures that a reasonable number of individuals can come together to reach decisions efficiently.

It's important to note that not all decisions may have required the same level of agreement. Some matters might have been settled through a simple majority vote, while others could have required a higher threshold. Nevertheless, the democratic process would have provided a mechanism for the passengers to collectively make decisions and navigate the challenges they faced on the Mayflower.
