A histogram has a horizontal axis labeled "Degrees Fahrenheit" from A to H and a vertical axis labeled "Number of days" from 0 to 8 in intervals of 1. The histogram contains vertical bars, where one vertical bar is centered over each of the horizontal axis tick marks. The heights of the vertical bars are as follows, where the Degrees Fahrenheit is listed first and the height is listed second: A, 1; B, 7; C, 6; D, 3; E, 6; F, 2; G, 1; H, 2.
​A: 30degrees​-32degrees
​E: 42degrees​-44degrees
​B: 33degrees​-35degrees
​F: 45degrees​-47degrees
​C: 36degrees​-38degrees

Part 1
How many days in February was the temperature in this city less than 39degrees​?

Answer 1

To determine how many days in February the temperature was less than 39 degrees Fahrenheit, we need to sum the number of days corresponding to the intervals A, B, and C from the histogram, since these intervals cover the range from 30 degrees to 38 degrees.

From the histogram data:
- Interval A (30-32 degrees): 1 day
- Interval B (33-35 degrees): 7 days
- Interval C (36-38 degrees): 6 days

Now, add these values together:
\[ 1 \text{ day} + 7 \text{ days} + 6 \text{ days} = 14 \text{ days} \]

Therefore, the temperature in this city was less than 39 degrees Fahrenheit on 14 days in February.
