270
6
=
45
Explanation:
There are 3 different sets of numbers involved here.
A set of six, a set of two and the set of all eight.
Each set has its own mean.
mean
=
Total
number of numbers
OR
M
=
T
N
Note that if you know the mean and how many numbers there are, you can find the total.
T
=
M
×
N
You can add numbers, you can add totals, but you may not add means together.
So, for all eight numbers: The total is
8
×
41
=
328
For two of the numbers: The total is
2
×
29
=
58
Therefore the total of the other six numbers is
328
−
58
=
270
The mean of the six numbers
=
270
6
=
45
Answer:
45 is the mean of other 6 numbers
Step-by-step explanation:
mean of eight numbers = 41
sum of eight numbers = 41x8
= 328
mean of two numbers = 29
sum of two numbers = 29x2
= 58
sum of other 6 numbers = 328-58
= 270
mean of other 6 numbers = 270/6
= 45
