To find the mean number of pies baked over the past 7 days, we first need to add up the total number of pies baked and then divide by the number of days.
The number of pies baked each day is:
- Tuesday: 0
- Wednesday: 10
- Thursday: 20
- Friday: 30
- Saturday: 40
- Sunday: 50
- Monday: 0
Now, let's add these numbers together:
\(0 + 10 + 20 + 30 + 40 + 50 + 0 = 150\)
Next, we divide the total by the number of days (7):
\(\text{Mean} = \frac{150}{7} \approx 21.43\)
Thus, the mean number of pies baked over the 7 days is approximately 21.43.
