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)

Answers

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:

[tex]\frac{-b+-\sqrt{b^{2} -4ac} }{2a}[/tex]

Where:

a = 1b = -12c = 11

A large company is interested in opening an on-site gym for the employees and would like to know what hours the employees would prefer to have the gym open.

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

Answers

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.
