If their mean is 5, then the numbers add up to 25.
Here are a few sets that do the job:
1, 2, 3, 4, 15
10, 20, 30, 40, -75
+2, -2, +99, -99, 25
1, 5, 5, 5, 9
2^9=512
There are 512 possible solutions

Answer:
c. positive w/ 1 outlier
Step-by-step explanation:
see picture
From the calculation below, the number of days it will take region d to catch up with region c is 8 days.
<h3>How do we calculate the number of days from the word problem?</h3>
The number of days it will take region d to catch up with region c can be calculated using the following formula:
c = d + 50y ................... (1)
c = the number of boxes sold by region c = 1,800
d = the number of boxes sold by region d = 1,400
y = number of days it will take region d to catch up = ?
Substituting the relevant values into equation (1) and solving for y, we have:
1,800 = 1,400 + 50y
1,800 - 1,400 = 50y
400 = 50y
y = 400 / 50 = 8
