Answer:
The total change in the water level was -7.15 cm
Step-by-step explanation:
Average Value
When a variable randomly changes its value, we usually need to use all those values by a representative number that best fits the data set.
One of the most-used representative measures is the mean or average value, where all the measures tend to be centered at this particular value.
We have been given an average change in the water level of a pond as -0.22 cm each day over a period of 32.5 days.
If we want to estimate the total change in the water level, we use the average times the duration of the measure, thus
-0.22 * 32.5 = -7.15 cm can be estimated as the required value.
The total change in the water level was -7.15 cm
