Calculate the average of each group and choose the appropriate sign (?):
12,16=?10,20,25,5,10
To solve this problem, we'll determine the average of both groups and compare the results:
- Step 1: Calculate the average of the first group (12,16).
The sum of the first group is 12+16=28.
There are 2 numbers, so the average is 228=14.
- Step 2: Calculate the average of the second group (10,20,25,5,10).
The sum of the second group is 10+20+25+5+10=70.
There are 5 numbers, so the average is 570=14.
- Step 3: Compare the averages.
Both groups have an average of 14; thus, the correct sign is =.
Since both averages are equal, the conclusion is that the groups have the same average.
Therefore, the solution to the problem is =.
