Question

frequency (number of days)
40-44 45-49 50-54 55-59 60-64 65-69
degrees fahrenheit
for how many days was the temperature recorded?
answer attempt 1 out of 10
days

Explanation:

Step1: Identify each bar's frequency

• 40 - 44: 7 days (from the bar height)
• 45 - 49: 7 days
• 50 - 54: 4 days
• 55 - 59: 4 days
• 60 - 64: 4 days
• 65 - 69: 5 days

Step2: Sum all frequencies

Sum = \( 7 + 7 + 4 + 4 + 4 + 5 \)
Calculate step - by - step:
\( 7+7 = 14 \)
\( 4 + 4+4=12 \)
\( 14+12 = 26 \)
\( 26 + 5=31 \)

Answer:

31
