The mean age of Lincoln's tee-ball team is 5. Suppose one of his 7-year-old teammates quits the team, but a 6-year-old joins the team. Is the mean age of Lincoln's team still 5? Explain your reasoning.

alright, the mean is the sum of the ages divided by the number of peoplpe ok, so example let's say he has 3 people on his team (not realistic but it's an example) 4yr and 7yr and 4yr 3 people 4+7+7=15 15/3=5, mean is 5 if the 7yr old leaves and is replaced witha 6 year old 4+6+4=14 14/3=4.6666666666666666666666666666667 the mean is no longer 5 because one of the values changed
