Final answer:
Weather data is collected from various sources including weather stations, ships, satellites, the ground, balloons, and sometimes pilots. Birds do not contribute to weather data collection.
Explanation:
In meteorology, weather data is collected from several sources such as weather stations, ships, satellites, the ground, balloons, and sometimes even pilots. These sources help to gather information about temperature, humidity, wind speed, precipitation, and other atmospheric conditions.
Weather stations are fixed installations equipped with instruments to measure and record weather conditions. Ships and buoys also collect weather data as they traverse different regions of the oceans. Satellites provide valuable information by capturing images, tracking cloud patterns, and monitoring global weather systems.
The data collected from these sources is used to analyze weather patterns, predict forecasts, and study climate change. Birds, on the other hand, do not directly contribute to weather data collection.

Answer:
We are given a inequality with the equality sign in terms of variable 'r' as:
Now we find the solution of the following inequality by solving for 'r'.
We subtract 3 from both side of the inequality to obtain:
Now we multiply both side by "-1" to obtain:
Now on dividing both side of the inequality by 2 we obtain:
Hence, the solution of the inequality are the set of all the points on the number line which are less than equal to -8.
i.e. the shaded region is to the left of -8 and closed circle at -8.
i.e. the solution is: (-∞,-8].
Number 2 graph is the correct graph of the solution.
