Which data collection method would provide an unbiased sample?
a.)
Emailing a questionnaire to the employees
b.)
Asking all employees who work from 8am - 5pm
c.)
Posting a request for survey volunteers in the company's breakroom
d.)
Asking five random employees from each shift
The data collection method that would provide an unbiased sample is "asking five random employees from each shift"
An unbiased sample is a sample whereby all the individuals have and equal chance of being picked for the research study.
In this case, asking five random employees from each shift is an unbiased sampling as everyone has an equal chance of being picked.
Option A is incorrect. Emailing a questionnaire to all the employees will be costly and isn't sampling.
Option B is incorrect. Asking all employees who work from 8am - 5pm is bias as others that doesn't work within the time frame aren't taken into consideration.
Option C is incorrect. Posting a request for the survey volunteers that are in the company's breakroom is biased.
Therefore, the correct option is D.

If anybody has 8 litres full of oil and there are two 5 and 3 litres empty jerry can where as there is no another jerry can out of those. How we can divide the oil in 4 and 4 in jerry can?
At the start, each can holds
• 5 L can : 0 L of oil
• 3 L : 0 L
Fill up the 5 L can completely:
• 5 L : 5 L
• 3 L : 0 L
Pour as much of the oil from the 5 L can into the 3 L can. This leaves you with
• 5 L : 2 L
• 3 L : 3 L
Empty the 5 L can:
• 5 L : 0 L
• 3 L : 3 L
Transfer the 3 L of oil into the 5 L can:
• 5 L : 3 L
• 3 L : 0 L
Fill up the 3 L can again:
• 5 L : 3 L
• 3 L : 3 L
Transfer as much of the oil as possible from the 3 L can into the 5 L can:
• 5 L : 5 L
• 3 L : 1 L
Empty the 5 L can:
• 5 L : 0 L
• 3 L : 1 L
Again, transfer the oil from the 3 L can to the 5 L can:
• 5 L : 1 L
• 3 L : 0 L
Fill up the 3 L can completely:
• 5 L : 1 L
• 3 L : 3 L
Transfer all the oil from the 3 L can to the 5 L can:
• 5 L : 4 L
• 3 L : 0 L

The median of your data would be 9.
First, align the numbers from least to greatest:

Next, identify which number is in the middle; if you have a hard time figuring that out you may want to strikethrough numbers on both sides until you have only one number left—that would be your median per se (i.e., 9 is the median of this data set).

ok so basically a letter is a type of written communication that can be written by hand or printed on paper.

A letter, or a written discussion between two parties, is any such message that is sent through the mail.
why and how do humans exist when (eventually) we're all just gonna die, either by mass extinction or we just... die out?
Answer:
The short answer is yes. The fossil record shows everything goes extinct, eventually. Almost all species that ever lived, over 99.9%, are extinct.
Humans have vulnerabilities. Large, warm-blooded animals like us don’t handle ecological disruptions well. Small, cold-blooded turtles and snakes can last months without food, so they survived. Big animals with fast metabolisms – tyrannosaurs, or humans – require lots of food, constantly.
So we’re vulnerable, but there are reasons to think humans are resistant to extinction, maybe uniquely so. We’re a deeply strange species – widespread, abundant, supremely adoptable – which all suggest we’ll stick around for a while
Which behavior would best describe someone who has good communication skills with customers ? a) Following up with some customers b) Talking to customers more than listening to them c) Repeating back what the customer says d) Interrupting customers frequently
Your answer is (A) i.e Following up with some customers!!

Lawns produce no crops but occupy more land (25 million acres) in the United States than any single crop such as corn or wheat. Does this mean the United States is producing inefficiently (inside the production possibilities curve)? Explain your answer.
Answer:In most U.S. states, there could be more lawn than any single irrigated crop. Hay predominates in the West, however, and in Nebraska and Kansas, there are more acres of corn than anything else
Explanation:
Lawns produce no crops but occupy more land (25 million acres) in the United States than any single crop such as corn or wheat. This means that the US is operating inefficiently and hence is at a point inside the production possibility curve.
What is Production possibility curve?The production possibilities curve is a graph which shows all of the different combinations of the output made which can be produced given the current resources and technology. In total, there are three types of production possibility curves. Namely, the straight line sloping down in the form of concave and convex graph.
In most of the U.S. states, there could be more lawn than any single irrigated crop. This decrease in the production possibilities curve means that the U.S. is operating inefficiently and hence it is at a point which isi inside of the production possibility curve in the graph.

Which expression is equivalent to x2 - 12x + 11?
O (x+11)(x + 1)
O (x - 11)(x+1)
O (x + 11)(x - 1)
o (x - 11)(x - 1)
Answer: o (x - 11)(x - 1)
Explanation:
You can find two values that has a sum of -12 and a product of 11:
[tex]x^{2} -12x+11\\(x-11)(x-1)[/tex]
Or you can use the quadratic formula:

Where:
a = 1b = -12c = 11“In fact, production theory is much simpler than consumption theory because the output of a production process is generally observable, whereas the “output” of consumption (utility) is not directly observable”. Explain this statement.
Answer:
Since the output of consumption is most likely waste it is hard to track where the waste is going. Whereas with production theory the output is the product which goes to the consumer. This is much more easy to observe and is therefore "directly observable."
