For 1. Positive correlation means if you plot a country's population and land size on a graph. There would be a linear regression line that's sloping upwards.
Since it's a scatterplot, there will be some that fall out of the line, but most of them should be on the line.
It's (A)
For 2. An outlier is a datapoint that's far, FAR away from the others, so it's (B)
For 3. (A), it's a single line-of-best fit that runs through the middle of the cluster of data points.
An extranet acts as a shared network, disseminating information present on the intranet. That is, if a private intranet shares some of its content with other users (be they sellers, customers, etc.), this shared network is what we call the extranet.
Intranet
Today, companies are looking for tools and methods to align internal communication, reduce costs, and centralize information and files. The intranet is one of these tools, which works restricted to a specific audience, such as a company. This way, collaborators can access it with their specific username and password.
The intranet is, then, a closed and internal network, and still allows the use of more communication protocols besides HTTP. Intranet access is typically done on a local server and a local network, which we call LAN, which means Local Area Network installed within the company.
This internal network connects users, allowing information exchange, file and document management, centralizing communication between users. With this tool, you can quickly and securely and efficiently connect companies and departments.
