How many prime numbers are there from 100?
'from 100' ??? If you mean 'less than 100' then there are 25 primes. If you mean 'more than 100' then the answer is infinite, just like numbers are infinite.
What is the mean of all the whole numbers between -410 and 400 and how did you solve it?
The count of the numbers is 410+1+400 = 811. To get the sum of all these numbers note that all the positive numbers cancel with their negative counterparts and you are left only with the numbers from -410 to -401 (inclusive). The sum of these numbers is -4055. So their mean is Sum/Count = -4055/811 = -5.
Geometric mean of 128 and 8?
For two numbers, the geometric mean is the sort of their product. Note I use * to mean multiply So here GM= sqrt (128*8) = sqrt (1024) =32
What does the - sign mean before a number?

What are all the composite numbers under 100?
So we eliminate prime numbers. Note that the number 1 is neither prime nor composite. We have left:4689101214151618202122242526272830323334353638394042444546484950515254555657586062636465666869707274757677788081828485868788909192939495969899100

How do you find the median of a set of 10 numbers?
List the numbers from least to greatest. Count in from both ends the same times and you will note there is no middle number, but 2 middle numbers. Take the average of the 2 middle numbers and that is the mean of the set.
