Find the mean of -4,-3,-1,-1,0,1

-1.3

The mean is their average so add them up and divide it by the number of values.

(-4) + (-3) + (-1) + ( -1) + (0) + (1) = -8

-8/6 = 1.333

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
