Using the Factor Theorem, which of the polynomial functions has the zeros 2, radical 3 , and negative radical 3 ?

Alja [10]

Using the factor theorem, it is found that the polynomial is:

$f(x) = x^3 - 2x^2 - 3x + 6$

Given by the first option

---------------------------

Given a polynomial f(x), this polynomial has roots $x_{1}, x_{2}, x_{n}$ using the factor theorem it can be written as: $a(x - x_{1})*(x - x_{2})*...*(x-x_n)$ , in which a is the leading coefficient.

---------------------------

In this question:

$x_1 = 2$
$x_2 = \sqrt{3}$
$x_3 = -\sqrt{3}$
By the options, leading coefficient $a = 1$

Thus:

$f(x) = (x - 2)(x - \sqrt{3})(x + \sqrt{3})$

$f(x) = (x - 2)(x^2 - 3)$

$f(x) = x^3 -2x^2 - 3x + 6$

Which is the polynomial.

12. If a manufacturer conducted a survey among randomly selected target market households and wanted to be 95% confident that th

Answer:

$n=\frac{0.5(1-0.5)}{(\frac{0.03}{1.96})^2}=1067.11$

And rounded up we have that n=1068

Step-by-step explanation:

We have the following info given:

$Confidence= 0.95$ the confidence level desired

$ME =0.03$ represent the margin of error desired

The margin of error for the proportion interval is given by this formula:

$ME=z_{\alpha/2}\sqrt{\frac{\hat p (1-\hat p)}{n}}$ (a)

The confidence level is 95% or 0.95, the significance is $\alpha=0.05$ and the critical value for this case using the normal standard distribution would be $z_{\alpha/2}=1.96$

Since we don't have prior information we can use $\hat p= 0.5$ as an unbiased estimator

Also we know that $ME =\pm 0.03$ and we are interested in order to find the value of n, if we solve n from equation (a) we got:

$n=\frac{\hat p (1-\hat p)}{(\frac{ME}{z})^2}$ (b)

And replacing into equation (b) the values from part a we got:

$n=\frac{0.5(1-0.5)}{(\frac{0.03}{1.96})^2}=1067.11$

And rounded up we have that n=1068

Ava has 34 candy bars. If

aliya0001 [1]

$\bf Step-by-step~explanation:$

If Ava has 34 candy bars, and each box can hold 5 bars, then we need to find out how many boxes that are filled up.

$\bf Step~1:$

Divide the number of candy bars (34), by the number each box can hold (5)

$\bf\frac{34}{5}=6.8$

Since we cannot have 6.8 boxes, we have to round down to 6.

$\boxed{\bf Our~final~answer:~6~boxes}$

$\bf Check~our~answer:$

To check our answer, we multiply the number of boxes (6), by the number of bars in each box (5), to get 30. We add Ava's extra bars (4), and we get the number we started off with: 34. This proves our answer is correct!
