Circle A has area of 500 in^2. The diameter of Circle B is three times the diameter of circle A. Estimate the area of circle B.

Answers

Answer:

750^2

Step-by-step explanation:

backtrack and find the diameter of circle A. A=πr, which means the diamater is about 159 1/11. three times the diameter will give 477 3/11, so the radius is 238 7/11. multiply it to 22/7 (π) then you get 750^2.

A class of 37 students took a test worth 100 points. The five-number summary of their scores is 55, 67, 73, 81, 98. Identify the FALSE statement: Group of answer choices At least 25% of the students scored a 67 or below. At least 18 students scored below a 67. At least 9 students scored between 67 and 73. At least 25% of the students scored an 81 or above.

Answers

Answer:

At least 18 students scored below a 67.

Step-by-step explanation:

Given the 5 number summary of scores obtained by 37 students in a test worth 100 points :

55, 67, 73, 81, 98

Minimum = 55

Q1 = 67

Q2 = 73

Q3 = 81

Maximum = 98

Q1 = first quartile = 25%

Atleast 25 % scored below 67 (True)

25% of 37 students = 0.25 * 37 = 9.25

Atleast 9 students scored below 67 (True)

Median, Q2 = 50%

Score between Q2 and Q1 = 50% - 25% = 25% ;

Hence, atleast 25 students scored between 73 and 67 ; meaning (0.25 *37) = 9.25 students Hence. Atleast, 9 students scored between 73 and 67 (True)

Third quartile = 75%

Percentage above third quarterile = (100 - 75)% = 25%

Hence, atleast 25% scored above 81 (True)

The false statement is At least 18 students scored below a 67.

Can someone help me please Effective leaders perform both management and leadership work. Does ethical decision making get lost in the complexity of work?Reading to question response: The Management MindsetThe management mindset is a rational response to time stress. There are only twenty-four hours in a day and everything we chose to do, including our work, play, family obligations, social engagements, and spiritual development or reflection must fit into that fixed container. But what does the time stress do to create the management mindset through which we see our organizational landscapes as stages for performance, and concomitantly how does this stage impact behavior?Lengel and Larsen (2010) drew on Ray Bradburys science fiction classic Fahrenheit 451 to shed light on the impact of time stress. Bradbury envisioned a future world in which individual uniqueness was subordinated to a common governmental vision. Translating to our context, this was a future in which personal value systems would be subordinated to a collective value system. His underlying thesis was that by killing their spirit to lead, people could effectively be controlled. The desire to control is a central feature of the management mindset that we will address later. For now the interesting inference from Bradburys work is that this control can be accomplished by simply keeping people busy and denying them access to a time and place to just talk. His metaphor for this time and place was the front porch (Bradbury p. 56). Without front porches and under time pressure, people would behave in ways that might not be in their best personal or collective interests.Certainly the pace of change facing businesses today and the drive to do more with less is keeping people busy. The forty hour work week is a distant memory for most organizational leaders. In a real sense, business is busyness, so half of Bradburys formula for control is clearly in place. But what about the front porches? Lengel and Larsen (2010) visualized front porches as bridges linking individuals to their shared community or commons. Front porches represent a time and place where private interests could be weighed against public interests in a relaxed atmosphere where formal relationships and the stress of busyness were absent. On front porches, people could just sit down together on rocking chairs and offer an open invitation for neighbors passing by to join in conversation without agenda or purpose beyond just being togetherjust talking. Front porches provide a stage for individuals to explore their uniqueness and remember their roots and responsibilities, and their obligations to the greater community. This is the context for deep ethical/moral inquiry and self reflection that handicaps the tension between collective intentions and individual values and ethics. It is also the context for sourcing courage in leadership. In this way these porches are stages for Quadrant 4 exploration.What do front porches and the spirit to lead have to do with teaching ethics and developing ethical people? Organizations have both static and dynamic qualities (Lengel and Larsen 2010). The static qualities represent the objective reference frame that is created to facilitate communication and organizational learning. The dynamic qualities have been traditionally referred to as the emergent informal organization. Management work focuses on control and maintenance of the static qualities of organizations while leadership work is typically focused on the emergent dynamic embracing learning and innovation. The management mindset views that static organization as reality and the dynamic as an anomaly to be dampened or controlled. In contrast the leadership mindset views the dynamic organization as the natural state and the static as the anomaly. Effective leaders perform both management and leadership work. But busyness eliminates front porches, and it is on front porches that leadership work is performed. Therefore, the management mindset tends to dominate organizational life. when preparing a flexible budget, the level of activity blank______. ( Wildcat , Red Alert , Daniel R.
