Explanation:
To find the sample variance and standard deviation, we need to first find the mean of the sample, and then use that to calculate the variance and standard deviation.
The mean of the sample is:
(15 + 37 + 23 + 18 + 17 + 10) / 6 = 16
Next, we'll find the difference between each value and the mean, square those differences, and divide the sum of the squared differences by the sample size minus one (n - 1):
(15 - 16)^2 = 1
(37 - 16)^2 = 361
(23 - 16)^2 = 49
(18 - 16)^2 = 4
(17 - 16)^2 = 1
(10 - 16)^2 = 36
The sum of the squared differences is: 1 + 361 + 49 + 4 + 1 + 36 = 452
The sample variance is: 452 / (6 - 1) = 452 / 5 = 90.4
Finally, the sample standard deviation is the square root of the sample variance:
The sample standard deviation is: sqrt(90.4) = 9.49
So, the sample variance is 90.40 and the sample standard deviation is 9.49.
Answer:
sample variance is 90.40 and the sample standard deviation is 9.49

How many more 3" x 3" linoleum tiles than 1' x 1' tiles will it take to cover a 9' x 9' floor?
(F) 144
(G) 63
(H) 1215
(J) 98
(K) none of these
Answer: (H) 1215.
Explanation:
To cover a 9' x 9' floor, we need (9 x 12) = 108 inches of flooring in each direction.
Each 1' x 1' tile covers an area of (12 x 12) = 144 square inches. Therefore, we need (108 x 108) / 144 = 81 tiles.
Each 3" x 3" tile covers an area of (3 x 3) = 9 square inches. Therefore, we need (108 x 108) / 9 = 12,096 tiles.
The difference in the number of tiles needed is: 12,096 - 81 = 12,015.
Therefore, we need 12,015 more 3" x 3" tiles than 1' x 1' tiles.
A scientist is studying wildlife. She estimates the population of bats in her state to be 345,000. She predicts the population to grow at an average annual rate of 1.2%. Using the scientist’s prediction, create an equation that models the population of bats, y, after x years.
Answer: y = 345,000 * (1 + 0.012)^x
Explanation: The population of bats can be modeled by an exponential growth equation of the form:
y = 345,000 * (1 + 0.012)^x
Where x represents the number of years. The initial population of bats is 345,000 and the average annual growth rate is 1.2%, represented by the factor of 1 + 0.012.

Using relevant and logical justification from your discipline (a political scientist, a sociologist, a journalist, a media technician or practitioner or studio technical operator), show the nexus between it and critical thinking.
As a political scientist, I would argue that critical thinking is a crucial component of understanding political systems and making informed decisions within those systems. In order to analyze political situations and outcomes, one must be able to assess evidence, consider multiple perspectives, and identify potential biases or assumptions. This type of analytical approach allows individuals to assess the legitimacy of political claims, understand the motivations of different actors, and make informed decisions about the political process.
Similarly, as a sociologist, I would argue that critical thinking is necessary in order to effectively analyze and understand social phenomena. In order to make sense of complex social issues, such as inequality, social movements, and power dynamics, sociologists must be able to evaluate evidence, identify patterns and connections, and consider multiple perspectives. This type of analytical approach allows sociologists to uncover the underlying causes of social problems and develop effective solutions.
In journalism, critical thinking is crucial in order to gather and report accurate and impartial information. Journalists must be able to assess the credibility of sources, identify potential biases, and gather multiple perspectives in order to create a comprehensive and fair representation of events and issues. This type of analytical approach helps to ensure that the information provided to the public is trustworthy and informative.
For a media technician or practitioner, critical thinking is important in order to effectively create and distribute media content. They must be able to assess the technical requirements of a project, identify potential problems and solutions, and evaluate the impact of their work on the intended audience. This type of analytical approach helps to ensure that the media content produced is technically sound and meets the needs of the audience.
Finally, as a studio technical operator, critical thinking is essential in order to effectively operate and maintain equipment and systems within a studio setting. They must be able to identify potential problems, assess the technical requirements of a production, and evaluate the impact of their work on the overall quality of the production. This type of analytical approach helps to ensure that the studio operates smoothly and efficiently, and that the end product meets the standards of the industry.
In all of these fields, critical thinking is a key component in understanding and solving complex issues, and in ensuring that information and media content is accurate, impartial, and effective.
The minute hand fell off a watch but the watch continued to work accurately. What time was it when the hour hand was at 17-minute mark?
A) 3:02
B) 3:17
C) 3:24
D) 4:17
When the hour hand was at 17-minute mark the time is 3:24, so the correct option is C.
What time was it when the hour hand was at 17-minute mark?To determine the time when the hour hand was at the 17-minute mark, we need to consider the relationship between the hour and minute hand on a clock.
In a standard clock, the minute hand moves 12 times faster than the hour hand. So, for every hour that passes, the minute hand completes a full revolution around the clock, while the hour hand moves one-twelfth of the distance.
Since the minute hand fell off the watch but the watch continued to work accurately, we can assume that the hour hand is functioning properly and keeping accurate time.
To find the time when the hour hand was at the 17-minute mark, we need to find a time where the hour hand is approximately one-twelfth of the way between two hour marks and the minute hand is at the 17-minute mark.
Among the given options, the closest one is:
C) 3:24
At 3:24, the hour hand would be close to the 4-hour mark, which is one-twelfth of the distance between the 3-hour and 4-hour marks. The minute hand would be at the 17-minute mark.

At the equilibrium price, how many meals would the Green Door Restaurant be willing to sell
Answer:
Explanation:
At the equilibrium price, the Green Door Restaurant would be willing to sell the quantity of meals that maximizes their profit. This is because, at the equilibrium price, the demand for the restaurant's meals is equal to the supply of meals that the restaurant is willing to sell. If the restaurant were to raise its price above the equilibrium, it would likely result in a decrease in demand and a decrease in the quantity of meals sold. On the other hand, if the restaurant were to lower its price below the equilibrium, it may result in an increase in demand, but the restaurant would earn less revenue per meal. The exact number of meals that the Green Door Restaurant would be willing to sell at the equilibrium price would depend on various factors such as the costs of production, the tastes and preferences of consumers, and the competition from other restaurants.
At the equilibrium price, the Green Door Restaurant would be willing to sell the quantity of meals that maximizes their profit. This is because, at the equilibrium price, the demand for the restaurant's meals is equal to the supply of meals that the restaurant is willing to sell.
What is an equilibrium?Equilibrium is the state in which market supply and demand balance each other, and as a result prices become stable. Generally, an over-supply of goods or services causes prices to go down, which results in higher demand while an under-supply or shortage causes prices to go up resulting in less demand. The balancing effect of supply and demand results in a state of equilibrium. A market in equilibrium demonstrates three characteristics: the behavior of agents is consistent, there are no incentives for agents to change behavior, and a dynamic process governs equilibrium outcomes.
