Answer:
A
Explanation:
The correct answer here would be that <u>less than 3 percent of Earth's water is freshwater containing no salt.</u>
<em>Generally speaking, about 71 % of the earth is made up of water. Out of this percentage, approximately 97 % is found in the oceans with less than 3 % being freshwater. About 68.7 % of the freshwater is locked-up as glacier and ice, 30.1 % is groundwater, while the remaining 1.2 % represents surface and other forms of freshwaters which include ground ice and permafrost, lakes, atmosphere, rivers, swamps and marshes, soil moisture, and the freshwater in living organisms. </em>
The correct option is A.
When analyzing data scientists look for patterns, that help them form predictions.
Patterns are rules that variations/characteristics follow, either in data or anything else patterns might be used for.
Example:
The fact that worms are found always 10 meters forom eachother (not true, it's an example) is a pattern, that will help you predict the location of the next worm.
