Find the arithmetic mean of the first five prime numbers.

Find the arithmetic mean of the first five prime numbers.

Correct Answer: 5.6

Step 1: Identify the first five prime numbers. The first five prime numbers are 2, 3, 5, 7, and 11.
Step 2: Add the first five prime numbers together. Calculate 2 + 3 + 5 + 7 + 11.
Step 3: Perform the addition. 2 + 3 = 5, then 5 + 5 = 10, then 10 + 7 = 17, and finally 17 + 11 = 28.
Step 4: Count how many numbers you added. There are 5 prime numbers.
Step 5: Divide the total sum by the number of prime numbers. Calculate 28 divided by 5.
Step 6: Perform the division. 28 / 5 = 5.6.

Arithmetic Mean – The arithmetic mean is calculated by summing a set of numbers and dividing by the count of those numbers.
Prime Numbers – Prime numbers are natural numbers greater than 1 that have no positive divisors other than 1 and themselves.
