The tool described is Planning Poker. It is a consensus-based technique used by agile development teams to estimate the relative effort or size of development goals in software development. Each team member uses cards with numerical weights, such as the Fibonacci sequence, to indicate their estimation of the complexity of a user story. The team members flip over their cards simultaneously, and any outliers, high or low values, are given an opportunity to explain their reasoning to the team. The process is repeated until a consensus is reached on the complexity of the user story. Planning Poker is often used in Scrum and other agile methodologies to plan and prioritize the work that needs to be done in an upcoming iteration.
the contents of an html file are arranged in a hierarchical structure, starting from the root html element itself and moving down to the text strings contained within individual page elements. true false
It's true. An HTML file is a document that contains the structure and content of a website.
The structure of an HTML file is arranged in a hierarchical fashion, meaning that there is a parent-child relationship between elements. The root element is the "html" element, which encloses all other elements on the page. From there, elements can be nested within other elements to create the desired structure and organization of the content on the page. For example, a "head" element can contain a "title" element, which in turn contains a text string that displays as the title of the webpage. This hierarchical structure allows for easy identification and manipulation of specific elements within the HTML document.

The characteristics that apply to fission are:
Involves the transmutation of elements.The process is used to generate electrical power.Heavily involves neutrons.High temperature is required at the initiation of the process.Radiation is emitted during the process.The characteristics that apply to fusion are:
Predominate in the interior of the sun.High temperature is required at the initiation of the process.Radiation is emitted during the process.Fission and fusion are both processes of nuclear energy production, but they have different mechanisms.
Fission is the splitting of a large nucleus into two or more smaller nuclei, releasing a large amount of energy in the process. Through fission, energy is released from the nucleus of an atom. The process involves splitting the nucleus of a heavy atom, such as uranium or plutonium, into two or more smaller nuclei. In the process, a large amount of energy is released in the form of heat and radiation, which can then be used to generate electrical power.
Fusion, on the other hand, is the process of combining two or more small nuclei into a single larger nucleus, also releasing energy in the process. Unlike fission, fusion is a process that occurs naturally in the core of stars, and is the main source of energy for our sun and other stars. Achieving a sustained reaction of fusion on Earth requires very high temperatures, and is still under development in many research labs around the world.

there are 65 apple trees in an orchard. each tree produces 805 apples. for each additional tree planted in the orchard, the output per tree drops by 7 apples. how many trees should be added to the existing orchard to maximize the total output of trees
The total output of apples can be maximized by adding a total of 9 trees to the existing orchard.
What is existing orchard?Existing orchard is an agricultural term used to describe an area of land where fruit trees have already been planted. This can be a commercial orchard, where the trees are managed and harvested for their fruit, or a residential orchard, which is typically a backyard or garden where fruit trees are planted for personal consumption and enjoyment. Orchards are often planted in rows, with trees spaced close together in order to maximize production and efficiency.
This is because the additional trees will produce 7 fewer apples each, adding up to 63 apples in total. The total output of apples will then be 805 x (65+9) = 54,785 apples. This is the maximum output that can be achieved with the existing orchard.
