Question

The table at the left shows the water level (in inches) of a reservoir for three month compared to the yearly average. Is the water level for the three-month preiod greater than or less than the yearly average? Explain.

June July August
-2 1/8 1 1/4 - 7/8

Answer 1

The water level for the three-month period is greater than the yearly average.

Step-by-step explanation:

The water level for the three-month period is greater than the yearly average. To determine this, we need to calculate the average water level for the three-month period and compare it with the yearly average. Let's calculate:

June: -2 inches

July: 1 1/4 inches = 1.25 inches

August: -7/8 inches = -0.875 inches

Now, calculate the average:

(-2 + 1.25 - 0.875) / 3 = -1.625/3 = -0.5417 inches

We can see that the average water level for the three-month period is -0.5417 inches, which is greater than the yearly average. Therefore, the water level for the three-month period is greater than the yearly average.
