Answer:
For #5: There are 3 children and 4 adults.
Step-by-step explanation:
Let x= number of children
y= number of adults
y = x + 1
x + y = 7
x + (x+1) = 7
x + x + 1 = 7
2x + 1 = 7
2x = 7 - 1
2x = 6
x = 6/2
x = 3
y = x + 1
y = 3 + 1
y = 4
Therefore, the number of children is 3 and the adults are 4.
Answer:
mean = 1.49
median = 1.53
Step-by-step explanation:
Using Excel, the procedure is the following
- Insert data set in a sheet. In my case I used cells A1 to AX1
- Compute mean with AVERAGE formula. In my case, AVERAGE(A1:AX1)
- Compute median with MEDIAN formula. In my case, MEDIAN(A1:AX1)
7.0 is an outlier because all data points are below 2.91
