Mean of the First Four Prime Numbers
To find the mean of the first four prime numbers, we first need to identify the prime numbers and then calculate their average.
Prime Numbers:
Prime numbers are natural numbers greater than 1 that have no divisors other than 1 and themselves. The first four prime numbers are 2, 3, 5, and 7.
Calculating the Mean:
To calculate the mean, we sum up the prime numbers and divide the sum by the total number of prime numbers.
Mean = (2 + 3 + 5 + 7) / 4
Solution:
Calculating the sum:
2 + 3 + 5 + 7 = 17
Dividing the sum by the total number of prime numbers:
Mean = 17 / 4
Simplifying the expression:
Mean = 4.25
Therefore, the mean of the first four prime numbers is 4.25, which corresponds to option 'D'.
Explanation:
- The mean is a measure of central tendency that represents the average value of a set of numbers.
- In this case, we are finding the mean of the first four prime numbers.
- The sum of the first four prime numbers is 17.
- Dividing the sum by the total number of prime numbers (4) gives us the mean.
- The mean of the first four prime numbers is 4.25.
- This is the correct answer, as stated in option 'D'.
