55-59
60-64
65-69
for how many days was the temperature recorded?
answer attempt 1 out of 2
days

Explanation:

Step1: Identify each bar's frequency

• 40 - 44: 4 days
• 45 - 49: 4 days
• 50 - 54: 5 days
• 55 - 59: 3 days
• 60 - 64: 3 days
• 65 - 69: 2 days

Step2: Sum the frequencies

Add all the days: \( 4 + 4 + 5 + 3 + 3 + 2 \)
First, \( 4 + 4 = 8 \), then \( 8 + 5 = 13 \), then \( 13 + 3 = 16 \), then \( 16 + 3 = 19 \), then \( 19 + 2 = 21 \)

Answer:

21
