Question

jim measured the daily rainfall in mm at the same spot in his garden for each day in the year (365 days). he recorded his results to the nearest millimeter. the results are shown in the following histogram: on approximately how many days was the rainfall less than 10 mm? a approximately 89 b approximately 135 c approximately 150 d approximately 215

Explanation:

Step1: Identify relevant bars

The bars representing rainfall less than 10 mm are the first two bars (0 - 5 mm and 5 - 10 mm).

Step2: Estimate bar - heights

The first bar (0 - 5 mm) has a height of approximately 135. The second bar (5 - 10 mm) has a height of approximately 75.

Step3: Calculate total days

Add the heights of the two relevant bars: $135 + 75=210$, which is approximately 215.

Answer:

D. Approximately 215
