Question

bobbie recorded how long she studied for five days in the
bobbies time chart

day	time (minutes)
tuesday	30
wednesday	40
thursday	30
friday	15

what is the mean of the time she studied?

Explanation:

Step1: Sum the study times

Add the minutes for each day: \( 35 + 30 + 40 + 30 + 15 \).
Calculation: \( 35 + 30 = 65 \), \( 65 + 40 = 105 \), \( 105 + 30 = 135 \), \( 135 + 15 = 150 \).

Step2: Divide by number of days

There are 5 days, so divide the total by 5: \( \frac{150}{5} \).
Calculation: \( 150 \div 5 = 30 \).

Answer:

30 minutes
