Answer:
...
Step-by-step explanation:
The most accurate and most likely probability is found by having a large, non-biased sample. The answer choice that shows this is D. Determine the ethnicity of 100 men (assumingly selected randomly) from a large city and determine the number who are Caucasian.
This answer choice showcases a large sample group, that was selected randomly from a large city. This would give you varied people to contribute to your study and give you an accurate representation of what the demographics of the city are.

Answer:
2. 2x² + 7x - 13
Step-by-step explanation:
3[x² - 1] - [x² - 7x + 10]
3x² - 3 - x² + 7x - 10
2x² - 13 + 7x
The above answer is a bit written in reverse, which is the exact same result.
So, after performing the Distributive Property, from there, you can combine all like-terms, as done above.
** Now, just in case you are wondering why that -7 has been altered to its opposite, it is because although -7x does not have another like-term to pair up with, IT IS STILL HOOKED UP TO ANOTHER NEGATIVE, so that -7x is REALLY 7x.
I am joyous to assist you anytime.
Well, lets first start off with combining like terms.
9x + 26 + 7x - 17 = 2x + (-3x) + 5x
9x + 7x + will give you 16x, and 26 - 17 will give you 9. Therefore, the first part of the equation is 16x + 9.
On the other side, you can combine all three terms (2x + 5x - 3x), which will give you 4x.
Using the above steps, you can figure that the answer is 16x +9 = 4x
