Answer:

Step-by-step explanation:

Let the number of questions be A.

Marissa got 85% on her math quiz and got 34 questions correct.

This Means 85% of the number of math questions =84

Therefore

85% of A = 34

This is

85/100 x A = 34

0.85 x A = 34

Divide both sides by 0.85

0.85/0.85 x A = 34/0.85

A = 40

The number of questions on the quiz was 40

If u(x) = x^5 - x^4 + x^2 and v (x) = -x^2 which expression is equivalent to ( u/ v) (x)

yawa3891 [41]

Answer:

$(u/v)(x)=-x^{3}+x^{2}-1$

Step-by-step explanation:

You have the following functions:

$u(x)=x^{5}-x^{4}+x^{2}\\v(x)=-x^{2}$

Therefore $(u/v)(x)$ indicates that you must divide both functions, as you can see below:

$(u/v)(x)=\frac{x^{5}-x^{4}+x^{2}}{-x^{2}}$

Simplify it. Therefore, you obtain:

$(u/v)(x)=\frac{x^{5}-x^{4}+x^{2}}{-x^{2}}\\\\(u/v)(x)=-x^{3}+x^{2}-1$

The results of the survey will most likely suffer from wording bias.

<h3><u>Wording Bias</u></h3>

The question asked in the survey contains certain characteristics that induce the respondent to think about the question asked in a negative way.

Thus, the word "wasteful" induces respondents to answer the question bearing in mind the negative criticism made by the questioner, which may influence the final answer.
