Answer:

860

Step-by-step explanation:

A non-response bias would mean that there are some non-response surveys, which will create a bias in the survey results. Because the survey didn't include information from those who are not responded.

If there will be 860 surveys back, this would prevent non-response bias

1.Which expressions are polynomials? Select each correct answer. Pick more then one.

madreJ [45]

If all the power of the variables are greater than or equal to zero, then the expression is a valid polynomial.

So,

$7x^{7}-x-5$

$35x^{2}$

$\frac{x}{5}+2$

are polynomials.

$x^{2} -x\sqrt{2}$

2 + s

$4x^{2} +y$

are all polynomials.

If the degree of the polynomial is 3, then it is a cubic polynomial. If the number of terms of a polynomial is 3, then it is a trinomial.

Hence, $-5x^{3}-4x+1$ is a cubic trinomial.

The highest power is the degree.

Hence, degree of the polynomial is 2 + 4 = 6.
