what do the extrema represent in the context of the situation? select all that apply.
a) the months when the water level is increasing or decreasing
b) the amount of rainfall in the everglades each month
c) the least water levels at this station
d) the greatest water levels at this station
e) the months when the water level at this station were at the lowest
f) the months when the water level at this station were at the highest

Explanation:

To solve this, we analyze each option:

• Option A: Extrema (max/min) don’t represent “increasing/decreasing” (that’s about slope/rate, not extrema). Eliminate A.
• Option B: The data is about water levels, not rainfall. Eliminate B.
• Option C: Extrema include minimum (least) water levels. This applies.
• Option D: Extrema include maximum (greatest) water levels. This applies.
• Option E: Extrema (minimums) correspond to months with the lowest water levels. This applies.
• Option F: Extrema (maximums) correspond to months with the highest water levels. This applies.

Answer:

C. the least water levels at this station
D. the greatest water levels at this station
E. the months when the water level at this station were at the lowest
F. the months when the water level at this station were at the highest
