I can't see the following you miss of didn't pin it I think....
Answer:
3.245
Step-by-step explanation:
2.22+1.51+1.86+2.06+3.48+4.57+3.27+5.40+5.45+4.34+2.64+2.14 then divide by twelve because that is the number of months :))))
You need to find the change in x and y
change in x = 12
change in y = 16
to find the distance you use a^2+ b^2 = c^2
or in this case x^2 + y^2 = d^2
144+256 = 400

=20
so distance equals 20
I hope this helps!
