precipitation in arches national park

month	jan	feb	mar	apr	may	jun	jul	aug	sept	oct	nov	dec
precipitation (in.)	1	0.56	1.03	0.83	1	0.35	0.77	0.88	1.02	1.23	0.68	0.62

Explanation:

Step1: Find the sum of precipitations

$1 + 0.56+1.03 + 0.83+1+0.35+0.77+0.88+1.02+1.23+0.68+0.62$
$=(1 + 1)+(0.56+0.35)+(1.03+0.83)+0.77+0.88+1.02+1.23+(0.68+0.62)$
$=2 + 0.91+1.86+0.77+0.88+1.02+1.23+1.3$
$=2+(0.91 + 1.86)+(0.77+0.88)+(1.02+1.23)+1.3$
$=2 + 2.77+1.65+2.25+1.3$
$=(2 + 2.77)+(1.65+2.25)+1.3$
$=4.77+3.9+1.3$
$=4.77+(3.9 + 1.3)$
$=4.77+5.2$
$=9.97$

Step2: Calculate the average

There are 12 months. The average is $\frac{9.97}{12}\approx0.83$

Answer:

$0.83$
