saveliy_v [14]

Answer:

(3-x) is the other factor.

Step-by-step explanation:

The given function is :

F(x)=-x^{2}+7x-12

One of the factor is (x-4)

We need to find the other factor.

It can be solved as follows :

F(x)=-x^{2}+4x+3x-12\\\\=(-x+3)(x-4)

So, the other factor is (3-x).

According to the Census Bureau, 3.34 people reside in the typical American household. A sample of 26 households in Arizona retir
Oduvanchick [21]

Answer:

Step-by-step explanation:

Given that:

Mean = 3.34

sample size = 26

sample mean = 2.7

standard deviation = 1.17

level of significance = 0.10

The null hypothesis and the alternative hypothesis can be computed as follows:

\mathtt{H_o: \mu \geq 3.34} \\ \\ \mathtt{H_1: \mu < 3.34}

degree of freedom = n - 1

degree of freedom = 26 -1

degree of freedom =  25

level of significance = 0.10

Since the alternative hypothesis contains <, then the test is left tailed

\mathtt{t_{\alpha, df} = t_{0.10, 25}}

\mathtt{t_{0.10, 25}} = - 1.316

The rejection region therefore consist of all values smaller than - 1.316, therefore ; reject H_o if t < -1.316

The test statistics can be computed as follows:

t = \dfrac{X - \mu}{\dfrac{\sigma}{\sqrt{n}}}

t = \dfrac{2.7 - 3.34}{\dfrac{1.17}{\sqrt{26}}}

t = \dfrac{-0.64}{\dfrac{1.17}{5.099}}

t = - 2.789

Decision Rule:  To reject the null hypothesis if the t test lies in the rejection region or less than the rejection region.

Conclusion: We  reject the null hypothesis since t = (- 2.789) < -1.316. Then we conclude that  the mean number of residents in the retirement community household is less than 3.34 persons.
