Chucky grabbed 11 items in the grocery store that each had a different price and had a mean cost of about $4.44. on his way to the register, he gave in to an impulse to add a 12th item: an entire wheel of cheese that cost $39.99. how will adding the wheel of cheese affect the mean and median?
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)
the answer would be 0.54
