Answer:

the equation that should be required is 0 = 2t

Step-by-step explanation:

Let us assume the hours of television be t

And, for hours outdoor be o

As the hours outdoors would be twice the hours of television so the equation is

0 = 2t

Therefore the equation that should be required is 0 = 2t

Mr. Acosta, a sociologist, is doing a study to see if there is a relationship between the age of a young adult (18 to 35 years o
Alik [6]

Answer:

There is a relationship between the age of a young adult and the type of movie preferred.

Step-by-step explanation:

In this case we need to test whether there is a significance relationship between the age of a young adult and the type of movie preferred.

The hypothesis can be defined as:

<em>H₀</em>: Age of a young adult and movie preference are independent.

<em>Hₐ</em>: Age of a young adult and movie preference are not independent.

The test statistic is given as follows:

\chi^{2}=\sum\limits^{n}_{i=1}{\frac{(O_{i}-E_{i})^{2}}{E_{i}}}

Consider the table below.

The formula to compute the expected frequencies is:

E_{i}=\frac{\text{Row Total}\times \text{Column Total}}{\text{Total}}

The Chi-square test statistic value is:

\chi^{2}=\sum\limits^{n}_{i=1}{\frac{(O_{i}-E_{i})^{2}}{E_{i}}}=2.6013

The significance level of the test is, <em>α</em> = 0.05.

The degrees of freedom of the test is,

df = (r - 1)(c - 1)

   = (3 - 1)(3 - 1)

   = 2 × 2

   = 4

Compute the <em>p</em>-value as follows:

<em>p</em>-value = 0.6266

*Use a Chi square table.

As the <em>p-</em>value is more than the significance level the null hypothesis was failed to be rejected.

Thus, concluding that there is a relationship between the age of a young adult (18 to 35 years old) and the type of movie preferred.

Solve the following equation <br><br>6x-1=3 (2x+4)-1
DIA [1.3K]
6x - 1 = 3(2x + 4) - 1
Distribute
6x - 1 = 6x + 12 - 1
Combine like terms
6x - 1 = 6x + 11
Add 1 and subtract 6x from each side
0 = 12
The equation has no real solution

What is 9 + 10 ? I’m so confused. People keep telling me it’s 21 but it doesn’t seem right.
juin [17]

Answer:

It's 21.

Step-by-step explanation:

The factors of 9 are 3 and 3. (You need to multiply 3x3 to get 9.) The factors of 10 are 5 and 2. But, if you multiply 3 by 5, which gives you 15, and multiply the other 3 by 2, which gives you 6, and then add 6 to 15, you get 21.
