Answer:

B. A random sample of 2,800 U.S. adults under 35.

Step-by-step explanation:

To have an unbiased and accurate sample, the sample should be representative of the population about which we are inferring.

Also, the bigger the sample size, the less margin of error we will have in the inference.

As the population in this survey is about the US adults under 35, the sample should be selected from this group.

From the options that select from this population, the largest sample is 2,800.

So the answer is Option B.

Step-by-step explanation:

A polynomial is a sum of terms, each of which is the product of a constant and some constellation of variables to integer non-negative powers. Anything with a variable in a denominator, a non-linear function such as absolute value, or square root (a fractional power) will <em>not</em> be a polynomial.

The constants in a polynomial may be rational or irrational. The polynomials we generally study are ones with real coefficients, but there is no reason why the coefficients could not be complex numbers.
