What is meant by sigma ?

Answers

Answer 1

Answer:

Sigma is the 18th letter of the Greek alphabet and is equivalent to our letter 'S'. In mathematics, the upper case sigma is used for the summation notation. The lower case sigma stands for standard deviation. If you notice, the two formulas that use these two symbols both start with the letter 's'.

A _________ license allows an author to set conditions for the free use and distribution of their work.

Answers

Answer: Creative commons license

A Creative commons license allows an author to set conditions for the free use and distribution of their work.

What is Creative commons license ?

Everyone, from small businesses to major institutions, now has a standardized approach to offer the public permission to use their creative works in accordance with copyright laws thanks to Creative Commons licenses.

Creators have a certain amount of control over their creative works thanks to copyright laws. People frequently need the creator's consent in order to use copyrighted works.

Creative Commons complies with copyright regulations. It enables authors to give everyone in the world permission to use their creations in specific ways. The most flexible license is CC BY.

If the author is properly credited, the user is permitted to redistribute, make derivative works (such a translation), and even utilize the publication for commercial purposes.

With CC licenses, the original author can choose how they want their creation to be used by others. When a creator makes their work available under a CC license, the general public is aware of what they are allowed and not allowed to do with the work.

The major drawback to utilizing Creative Commons licenses is that, with the exception of the two most restricted licenses, you must request permission to use your work in advance; consequently, you can never be certain who is using it or profiting from it.

Answers

I would say that this is more of an open-ended question.

Explanation:

The reason I think this is because it is asking for something more than "Do the leaves change color?" That would be a closed ended question because it is asking for a simple answer.

I don't think it is a leading question because the question isn't worded in a way that would lead you to answer in a certain way.

Answers to open ended questions require more thought and effort than closed-ended questions, but they generally are pretty clear in what they are asking.

Read the article “Walking the Quechee Gorge”:

Walking is the best way to see the Quechee Gorge. The gorge is known as the Grand Canyon of Vermont. When glaciers were melting during the last ice age, the moving water dug away at the bedrock of this area. The result is the magnificent Quechee Gorge with the Ottauquechee River running through it. Walking around the gorge provides visitors with exercise options and different perspectives.

First of all, walking the hiking trails provides tourists with the opportunity to exercise. Hikers may choose to walk along the pathways at the top of the gorge, which is a mile long. They can enjoy the fall colors and the fresh scent of pine trees. Adventurous individuals may choose to walk to the bottom of the gorge. The gorge is 165 feet deep, but the gravel hiking trail takes visitors safely to the bottom. There, hikers can take a break and remove their shoes. They can wade in the shallow waters or sit on a rock to rest. Then they can climb back to the top of the gorge.

Walking around the Quechee Gorge provides options. There are so many things to see! The lengths of the trails are listed, so hikers can decide how far they would like to walk. Visitors can walk along the top of the bridge overlooking the gorge. The bridge has a separate section for pedestrians that is separated from the roadway by a safety fence. Other hikers can walk to the dam and waterfall at the head of the gorge. If tourists get tired, they can rest at the Quechee Gorge Visitor Center or enjoy a meal in the picnic area beside the gorge. Visitors get to choose their adventure.

Finally, the Quechee Gorge is a photographer's dream because there are so many different perspectives to enjoy. At the dam, photographers can capture the smooth line of water falling over the dam into the turbulent waterfalls below. The bridge offers a magnificent view of the length of the gorge. Some photographers may wish to capture the steel curves of the bridge itself. Hikers can take pictures from different spots along the trail, including a picture of the same bridge from the bottom of the gorge. The bumpy rocks at the bottom of the gorge contrast with the smooth, rushing water of the river. With such a wealth of perspectives, even beginning photographers will produce phenomenal pictures.

Indeed, the perspectives, options, and physical exercise available at Quechee Gorge make this natural wonder a mandatory stop for walkers of all ages.

Read the article “An Aerial View”:

The best way to see the Quechee Gorge is by taking a hot air balloon ride. The gorge is 165 feet deep, with the Ottauquechee River at the bottom. It was formed when glaciers melted during the last ice age and are known as Vermont's Grand Canyon. Taking a hot air balloon ride through the gorge is a unique group experience with unparalleled views—and that is only part of the tour!

Taking a ride in a hot air balloon is already a unique experience. Visitors watch as the pilot tests the air currents with a helium balloon and makes a flight plan. The balloon is laid out on the grass and filled with cool air. Then, the pilot turns on the burners, which heat the balloon's air and cause the balloon to rise. Each balloon carries up to four passengers in addition to the pilot. As a result, tourists can enjoy the experience as a private group. Once the hot air balloon is in the air, the skilled pilot puts it into the paths of different air currents. Since air currents change daily, every ride is unique.

The aerial views from the hot air balloon are unparalleled. The hot air balloon floats above the dam and waterfall. Passengers can see people lining the steel bridge over the gorge. Then the hot air balloon floats just above the river. This relaxing trip allows visitors to enjoy the rushing water and watch for wildlife in the forest. The pilot also takes the hot air balloon high into the sky. Tourists can see the nearby mountains. Since they are traveling in a hot air balloon, visitors are treated to a 360-degree view of their surroundings.

The Quechee Gorge is only part of the hot air balloon tour. Passengers also enjoy seeing covered bridges and farms. They can touch the leaves on the trees. The hot air balloon may even make a quick dip into the water! Visitors admire the beautiful villages of Vermont and take pictures of the picturesque countryside.

At the end of the tour, passengers will without a doubt say that a hot air balloon ride is the best way to see the Quechee Gorge.

What information does the reader learn from “An Aerial View” that is also included in “Walking the Quechee Gorge”?

Each balloon carries up to four passengers in addition to the pilot.
The gravel hiking trail takes visitors safely to the bottom of the gorge.
There is the Quechee Gorge Visitors Center that lets visitors rest.

He was a good magician, because he only used his spells to make bad people good. And if they improved, he would take his magic spell off them. Frankel lived by himself in a large house, but he never did any housework. He used his magic spells to make his life easier and more comfortable. "Why waste time on housework?" he would say. "What matters is my magic. That's much more important." But the housework had to be done by somebody. So Frankel used spells to make his furniture do it. He would cast a spell and say, "Chair, wash my shirt," and "Brush, sweep the floor." Then the chair and the brush would grow arms and legs and wash his shirt and sweep the floor. Many years went by and slowly Frankel grew older and older. One day when he was sitting alone by his fire, he thought to himself. "I'm getting old. Who will do all my work, when I've gone? If nobody does it, then all my knowiedge of magic will be wasted. I must look for a Studeni, someone suitable; smart, intelligent, hard-working young boy.
