Answer
$1101.2$
Work Step by Step
The question asks us to find the mean annual worldwide coal production. To find the mean, we first need to find the total amount of coal produced across the 10 years:
Total = $1094+1071.8+1112.1+1037.5+1026.6+1146.6+1171.8+1174.9+1084.4+1092.6$
= $11012.3$
Now that we have the total, to find the mean we need to divide it by the number of years used, which in this case is 10.
So:
Mean = $\frac{11012.3}{10}$
=$1101.23 \approx 1101.2$
