Answer:
Pretty is correct in saying that the mean of the first 10 odd numbers is 10.
Step-by-step explanation:
To find the answer to the question, first, we need to know what even numbers and odd numbers are.
Even numbers are the numbers which either end with 0, 2, 4, 6, or 8, or, in other words, All numbers divisible by two are called even numbers. Note that this also includes the individual numbers 0, 2, 4, 6, and 8.
Now, What are Odd Numbers? The numbers which are not even are called odd numbers. This means that all numbers ending with 1, 3, 5, 7, and 9 are odd numbers. Also note that the individual numbers 1, 3, 5, 7 and 9 are also odd numbers. Thus, the numbers which are not divisible by 2 are called odd numbers.
The first 10 odd numbers are 1, 3, 5, 7, 9, 11, 13, 15, 17, 19.
Their sum is 100.
So, the mean of first 10 od numbers is 100/10 = 10.
Thus, Pretty is correct in saying that the mean of the first 10 odd numbers is 10.
