The prime numbers between 80 and 90 are 83 and 89.
-1
It's 1/10 the sum of all of those numbers.
There are no prime numbers between 70 and 80 because all the numbers in that range have factors other than 1 and themselves. For example, 72 can be divided evenly by 2, 3, 4, 6, 8, 9, 12, 18, 24, and 36, so it is not a prime number. Similarly, all the other numbers between 70 and 80 have multiple factors, making them composite numbers.
There are an infinite number of sets with mean 80. Here are some: {80, 80, 80}, {80, 80, 80, 80, 80, 80} {79, 80, 81}, {79, 79, 80, 81, 81}, {79, 79, 80, 82} (1, 80, 159}, {-40, 200} To produce a set of n numbers with mean 80, start with any set of n-1 numbers. Suppose their sum is S. Then add the number 80*n-S to the set. You will now have n numbers whose sum is S+80*n-S = 80*n So the mean of this set is 80.
The prime numbers between 80 and 90 are 83 and 89.

There are 39 odd numbers between 1 and 80.
No; it is divisible only by its factors (1, 2, 4, 5, 8, 10, 16, 20, 40, and 80).
It's 1/10 the sum of all of those numbers.
Just 1.

Any multiples of 80 are divisible by 80. Three examples: 80 / 80 = 1 : 160 / 80 = 2 : 800 / 80 = 10
There are an infinite number of sets with mean 80. Here are some: {80, 80, 80}, {80, 80, 80, 80, 80, 80} {79, 80, 81}, {79, 79, 80, 81, 81}, {79, 79, 80, 82} (1, 80, 159}, {-40, 200} To produce a set of n numbers with mean 80, start with any set of n-1 numbers.

The prime numbers from 1 to 80 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, and 79.
