If YV = 28 in, find the length of the major arc VYX. Round to the nearest tenth ( one decimal place).
denpristay [2]

Answer:

VYX=84.3in

Step-by-step explanation:

Given

YV = 28in

\angle WZX = 15^\circ

See attachment

Required

Determine the length of VYX

First, calculate the major angle VZX

\theta = \angle VZX = 360 - \angle WZX

\theta = \angle VZX = 360 - 15

\theta = \angle VZX = 345

\theta = 345

The length of arc VYX, is:

L=\frac{\theta}{360} * 2\pi r

Where

r = \frac{1}{2} * Diameter

r = \frac{1}{2} * YV

r = \frac{1}{2} * 28

r = 14

So:

L=\frac{\theta}{360} * 2\pi r

L=\frac{345}{360} * 2 * \frac{22}{7} *14

L=\frac{345}{360} * 2 * 22 *2

L=\frac{345* 2 * 22 *2}{360}

L=\frac{30360}{360}

L=84.3in

Hence, the length of VYX is:

VYX=84.3in

1.  What is the most important thing that must be true about a sample so that you can make a valid inference about the populatio
MissTica
<span>1.) The most important thing that must be true about a sample so that you can make a valid inference about the population is that the sample must not be biased.

2.) </span>I<span>t is important to take a random sample of the population you want to study because the population may be too large that it might be impossible or too expensive to conduct a survey on a population.

3.) </span><span>An outlier is an observation point that is distant from other observations. It can be too small or too big compared to other observations.</span>

The measure of center that is more affected by outliers in the data is the mean, because since the mean is obtained by the sum of the data divided by the number of the data set. Any 'too big' number or 'too small' number will affect the sum of the data set.

4.) Given that <span>Sam conducted a survey to find out the favorite weekend activity of the students his middle school. He asked 20 of his classmates. He found out that the favorite weekend activity of his middle school is playing video games because 75% of the students he surveyed liked to play video games.

</span><span>Sam’s sample may not be valid because he drew a sample only from his class to make an inference about the entire middle school students.

</span>For <span>Sam to improve his survey to be more representative of his school he must draw a random sample from all the classes that make up the middle school.</span>

Maxine is buying extra pages for her photo album. Each page holds exactly 8 photos. Sketch a graph to show the maximum number of
erastovalidia [21]
Ok so I can't sketch a graph for you because I don't know how to but i can give a formula that will help you graph it on your own. The equation is y = 8x having x represent the amount of extra pages you want to add. I came to this equation because if 8 photos can fit in each extra page and x represents the the extra pages then 8 photos is the slope for the equation y = mx + b. So if you were to graph this you will get a continuous line because it has no holes.

What is the equation of the line that is horizontal and goes through the y-axis<br> at -4?
Ivan
Y = mx + b, m = 0. The equation becomes y = b, where b is the y-coordinate of the y-intercept.
