The geometric mean of two numbers x and y is √(xy).
So, if the geometric mean of 3 and a is 9 =>
9 = √(3a)
=> 9^2 = 3a
=> a = 9^2 / 3
a = 81 / 3
a = 27
Answer: the value of a is 27.
Answer: The mode is: 3 . The range is: 6 .

It would be best to list this values in the data set given, from least to greatest:
________________________________________________
{ 3, 3, 3, 3, 4, 5, 5, 6, 9 } .
________________________________________________
The mode is the number that occurs most frequently in the data set, which is: "3".
_________________________________________________________
{The number, "3", occurs FOUR (4) times. The number, "4", occurs ONE (1) time. The number, "5", occurs TWO (2) times. The number, "6", occurs ONE (1) time. The number, "9", occurs ONE (1) time.}.
___________________________________________________
The range is calculated from subtracting the LOWEST value in the data set FROM the HIGHEST value in the data set.
____________________________________________________
The lowest values in the data set is: "3" .
The highest value in the data set is: "9" .
________________________________________________
To calculate the range: 9 <span>− 3 = 6 . The range is: "6".

Answer: The mode is: 3 . The range is: 6 .
