Answer:
mean=sum of data/no of data
=12/3
=4
Step-by-step explanation:
therefore mean=4
I would solve it for B, but that's just what I think. So you would do -12 time -2 which is 24, then subtract 24 from both sides so that you would get B=-31
2 because there are 4 numbers of edges and 4 vertices
Answer:
12 divided by 2 + 4 - 2 x 3 is 4
Step-by-step explanation:
I did 12 divided by 2 first which was 6 then added 4 subtracted it by 2 then multiplied it by 3 and got 4.
