Answer 2

Answer:

9 is the arithmetic mean of the given value.

Explanation:

• In context to the given ,we have to find the arithmetic mean of the  value given.
• Given values,

⇒ 2, 7, 9 and 18

Solution,

we know that;

• The arithmetic mean or average is simply the sum of collection of number divided by the count of numbers in collection.

⇒ The sum of the given value =  2 + 7 + 9 + 18 = 36

⇒ Total count of the number of values = 4

In respect to the statement of arithmetic mean ;

⇒ Arithmetic mean =  The sum of the given value  /  Total count of the number of values

⇒ Arithmetic mean =  36 / 4 = 9

∴ 9 is the arithmetic mean of the given value.
