Question 967132
# 1


Average = mean = (Total)/5


So because the average is 19, we know that x/5 = 19 leads to x = 95 being the total of the ages.

# 2


Let's say that the parents are about the same age. Say age 30 each. So that means 30*2 = 60 years are taken up by the parents only. 95 - 60 = 35 years are devoted to the kids. 


If the kids are ages 10, 11, and 14, then we have their ages add to 35. 10+11+14 = 35


Note: this is NOT the only way to distribute the ages

# 3


The mode is 4 because we have 2 members who are 4 years old. Everyone else is of some other age which means those other numbers only pop up once. The number 4 pops up twice, which is the most frequent. So that's why 4 is the mode.
