A school was attempting to determine the proportion of students who have access to the internet in their homes. Demographic data

Likurg_2 [28]

Answer:

Z = -1.789

P value = 0.036807

Step-by-step explanation:

Here

H0: p = 0.85 students will have access to the internet at home

Ha: p < 0.85 students will have access to the internet at home

As per the given data, out of 120 sampled students, 95 have access to internet at home

This is 79.17 % of the total number of sampled students.

The Z values is given by

$Z = \frac{p-p'}{\sqrt{\frac{p(1-p)}{n} } }$

Substituting the given values, we get -

$Z = \frac{0.7917-0.85}{\sqrt{\frac{0.85(1-0.85)}{120} } }\\Z = -1.789$

The sample proportion of 0.7917 is about -1.789 standard errors below the population proportion given in the null hypothesis.

Considering, result is significant at p < .05, the P-Value is .036807.

Line segment YV of rectangle YVWX measures 24 units.

oksian1 [2.3K]

Answer: $YX=13.85\ units$

Step-by-step explanation:

<h3> The complete exercise is: "Line segment YV of rectangle YVWX measures 24 units. What is the length of line segment YX?"</h3><h3> The missing figure is attached.</h3>

Since the figure is a rectangle, you know that:

$WV=YX\\\\YV=XW=24$

Notice that the segment YV divides the rectangle into two equal Right triangles.

Knowing the above, you can use the following Trigonometric Identity:

$tan\alpha =\frac{opposite}{adjacent}$

You can identify that:

$\alpha =30\°\\\\opposite=YX\\\\adjacent=YV=24$

Therefore, in order to find the length of the segment YX, you must substitute values into $tan\alpha =\frac{opposite}{adjacent}$ and then you must solve for YX.

You get that this is:

$tan(30\°)=\frac{YX}{24}\\\\(24)(tan(30\°))=YX\\\\YX=13.85$
