Answer:
4.24
Explanation:
First you find the mean of the data set, which is 7. Then to find standard deviation you have to follow the formula which tells you to subtract the mean from each number under the square root : √(2 - 7)^2 + (9 - 7)^2 + (10 - 7)^2 + (4 - 7)^2 + (8 - 7)^2 + (4 - 7)^2 + (12 - 7). Once you solve the parenthesis you square it, once you square it the negatives won't matter. That will leave you with this : √(25 + 4 + 9 + 9 + 25). The formula tells you to find the sum of those numbers (which is 72) then subtract one from how many numbers there are, 5 - 1 = 4, and divide your sum by that number. So 72 / 4 = 18. Then you find the square root of 18 and that becomes your answer.

<h2>
APPEND ONLY</h2>
Unlike traditional databases, blockchain is designed to be an "append-only" data structure. That means you can only append new data in the form of additional blocks, which will then be chained together with previous blocks of data. All data is permanently stored across more nodes and cannot be altered.
Answer:
On-line css
Explanation:
Web design is the development of web pages using web development tools like HTML ( hypertext mark-up language), CSS and JavaScript. HTML is not the main code itself, because it only uses it's tags of elements to mark layout of the page. External and in-line css are used differently. In-line css is used directly on the HTML elements in the HTML file to style the element property, but external CSS is a CSS file that addresses a html element file.
