Question 1089676
.
<pre>
The mean (or the arithmetic mean, or average) is the sum of addends divided by the number of addends.


We can write the sum of addends as 160000 + 120000 + 2*60000 + 40000 + 5*32000.


The number of addends is 1 + 1 + 2 + 1 + 5.


Therefore, the mean = {{{(160000 + 120000 + 2*60000 + 40000 + 5*32000)/(1 + 1 + 2 + 1 + 5)}}} = {{{600000/10}}} = 60000.

Solved.
