12x^3-11x^2+9x+18 divided by 4x+3

put he division into fraction

12x^3-11x^2+9x+18/4 x +3

reduced fraction by 2

12x^3-11x^2+9x+9/2 x +3

Which explanation can be used to informally derive the formula for the volume of a cone?.
Elis [28]

The statement that is correct about the volume of the cone is, a cylinder is exactly 3 times bigger than a cone with the same height and radius. Therefore, the formula for the volume of a cone is 1/3 of the volume of a cylinder with the same height and radius.

<h3>The formula for the volume of a cone</h3>

If we look carefully at a cylinder and the cone, if both the objects have the same radius, still the volume of both the objects is different, that difference is been created because the cone is gradually decreasing to a point while the cylinder is of the same radius during the entire length.

This makes a difference in the volume of the two objects.

Therefore, the statement that is correct about the volume of the cone is, a cylinder is exactly 3 times bigger than a cone with the same height and radius.

Hence, the formula for the volume of a cone is 1/3 of the volume of a cylinder with the same height and radius.

Which of the following scenarios is most likely to give the best approximation of the true probability of the event specified?
Sergeeva-Olga [200]
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.

I hope this helps! :)
