Use the rational root theorem to list all possible rational roots for the equation.

Alik [6]

Answer:

The possible rational roots are

$\pm 1, \pm 2,\pm3,\pm6,\pm \frac{1}{3},\pm \frac{2}{3}$

Step-by-step explanation:

We have been given the equation 3x^3+9x-6=0 and we have to list all possible rational roots by rational root theorem.

The factors of constant term are $1, 2, 3,6$

The factors of leading coefficient are $1,3,$

From ration root theorem, the possible roots are the ratio of the factors of the constant term and the factors of the leading coefficient. We include both positive as well as negative, hence we must include plus minus.

$\pm\frac{1,2,3,6}{1,3}\\\\ =\pm 1, \pm 2,\pm3,\pm6,\pm \frac{1}{3},\pm \frac{2}{3}$

Can someone please explain to me how to find the arc measurement?

xenn [34]

A circle is 360° , if youdivide<span> an arc's </span>degree measure<span> by 360°, you find the fraction of the circle's </span>circumference<span> that the arc</span>makes<span> up. Then, if you multiply the length all the way around the circle </span>by that fraction, you get the length along the arc.

Julia surveyed twenty households on her street to determine the average number of children living in each household. the tables

Lerok [7]

The difference between the mean of the sample and the mean of the population is A. 0.55

<h3>Calculations and Parameters:</h3>

Given the population data is:

0 3 3 1 3 2 2 2 5 4 3 3 3 0 1 2 0 2 3 3

The sample data is:

5 3 0 2 4

The mean of the population data is:
45/20= 2.25

The mean of the sample data is:

14/5= 2.8

Therefore, the difference between the mean of the sample and the population is:

2.8-2.25= 0.55
