Which sentence can represent the inequality 2.4 (6.2 minus x) greater-than negative 4.5? Two and four tenths times six and two t

enths minus a number is larger than negative four and five tenths. Two and four tenths multiplied by the difference of six and two tenths and a number is more than negative four and five tenths. The difference of six and two tenths and a number multiplied by two and four tenths is not less than negative four and five tenths. The product of six and two tenths minus a number and two and four tenths is at minimum negative four and five tenths.

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.

marissa [1.9K]

Answer:

Option B. \frac{1}{6}

Step-by-step explanation:

we know that

The frequency is equal to the number of cycles divided by the time

Remember that

1 cycle = 1 full wave to repeat itself

In this problem

From o to 12 seconds ------> there are 2 cycles

therefore

The frequency is equal to

f=\frac{2}{12}=\frac{1}{6}
