In one sentence, describe what the following article is about: The duplication is necessary to keep the original regions separate for one part and unify the other. Once you have this new object, you can remove the fill or give it a very transparent fill and a thicker border. Look at the image, showing the result of having done this with Northern Ireland and the entire island. Place the object showing the complete island is now in a lower layer (use the "End" button on your keyboard), so that the border only shows when it crosses the island. Create a shape that covers the shape of the stroke you wish to eliminate and then use the tool Path->Cut Path. This will divide the border into two pieces so that you can erase (type delete) the border you don't want.
Summary: Select all the objects that are part of the same group, duplicate them (ctrl+d) and unify them (Path->Union). Cut the border that delineates Northern Ireland so that it stops at the ocean and doesn't follow the coast of Northern Ireland.

Take all of your calculated returns and add them together. Then, divide by the number of returns you are using, n, to find the mean return. This represents the average return over the time period you are measuring. Specifically, the mean, m, is calculated as follows: m =(R1+R2+...Rn)/(n). For example, imagine that you had 5 periods that had calculated returns of 0.2, -0.1, -0.3, 0.4, and 0.1. You would add these together to get 0.3 then divide by the number of periods, n, which is 5. Therefore, your mean, m, would be 0.3/5, or 0.06. For every return, Rn, a deviation, Dn, from the mean return, m, can be found. The equation for finding Dn can be expressed simply as Dn=Rn-m. Complete this calculation for all returns within the range you are measuring.  Using the previous example, you would subtract your mean, 0.06, from each of the returns to get a deviation for each. These would be: D1=0.2-0.06, or 0.14 D2=-0.1-0.06, or -0.16 D3=-0.3-0.06, or -0.36 D4=0.4-0.06, or 0.34 D5=0.1-0.06, or 0.04 Your next step is to find the mean variance of the returns by summing the squared individual deviations from the mean of the returns. The equation for finding the variance, S, can be expressed as: S=(D1^2+D2^2+...Dn^2)/(n-1). Again, sum the squares of the deviations, Dn, and divide by the total number of variances minus 1, n-1, to get your mean variance.  First, square your deviations from the last step. These would be, in order: 0.0196, 0.0256, 0.1296, 0.1156, 0.0016. Sum these numbers to get 0.292. Then, divide by n-1, which is 4, to get 0.073. So, S=0.073 in the example. The volatility is calculated as the square root of the variance, S. This can be calculated as V=sqrt(S). This "square root" measures the deviation of a set of returns (perhaps daily, weekly or monthly returns) from their mean. It is also called the Root Mean Square, or RMS, of the deviations from the mean return. It is also called the standard deviation of the returns.  In the example, this would just be the square root of S, which is 0.073. So, V=0.270. This number has been rounded to three decimal places. You may choose to keep more decimals to be more accurate.  A stock whose price varies wildly (meaning a wide variation in returns) will have a large volatility compared to a stock whose returns have a small variation. By way of comparison, for money in a bank account with a fixed interest rate, every return equals the mean (i.e., there's no deviation) and the volatility is 0.

Problem: Article: The first step in doing something new is to come up with some fresh ideas. Start by generating a list of things you’ve always wanted to do. Remember that there are no wrong answers when you’re brainstorming! Aim for at least five items on your list.  Perhaps you’ve always wanted to skydive, bungee jump, or go white water rafting. Maybe you’ve always wanted to write a book, perform at an open mic, or grow your own garden. Maybe you’ve always wanted to work as a barista, make a short film, or try a vegan diet. Another way to generate some new ideas is to make a list of things you’d like to learn. Learning new things is a great way to meet people, have fun, and feel a sense of fulfillment. Aim to come up with at least five things you’d like to learn.  Perhaps you’d like to learn a new language, such as Spanish, Italian, or Chinese. Perhaps you’d like to learn a new creative skill, such as photography, pottery, or landscape painting. Perhaps you’d like to learn how to cook, do yoga, or write poetry. Finally, you can add to this ongoing list of new things by listing places (or things) that you’ve always wanted to see. Traveling to a new place (even someplace that is just around the corner) can open your eyes to new possibilities.  Maybe you have always wanted to visit the Louvre in Paris and see the Mona Lisa. Maybe you have always wanted to climb a mountain in the Alps. Maybe there is a restaurant in your city that you’ve always wanted to try. You don’t need to think too hard about it. Simply select the item from these lists that jumps out at you, makes your heart race, and gets you a little excited. This is the first new thing you should do. Even if it is seems big and far away, with a little planning, you can do it. Don't get caught up in choosing something. Just pick an idea that excites you!
Summary:
Write down things you’ve always wanted to do. Make of list things you want to learn. Create a list of places you want to see. Choose something from these lists.
