What is the mean of -3, 4, 8, -1, -4, -2, 0, 2, 5, 2, -3, 1

3/4 or .75

Step-by-step explanation:

The mean means the average so you would add up all the numbers then divide by how many numbers there are

-3+4+8+-1+-4+-2+0+2+5+2+-3+1= 9

9/12= 3/4 or .75

depends whether or not you want it in fraction or decimal form

0.75

Step-by-step explanation:

Mean is simply the average of all the numbers , that is all the numbers will be sum up and divided by the frequency

that is

-3 + 4 + 8 +(-1)+ (-4) + (-2) + 0 + 2 + 5 + 2 + (-3) + 1 / 12

= 9/12

= 0.75

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
