The number 356 is not prime. You should immediately notice that it is an even number, divisible by two, therefore it cannot be prime. Only odd numbers can be prime.
What 4 numbers is the mean of 6?
To find the four numbers that have a mean of 6, we need to consider that the mean is the average of all the numbers. Therefore, the sum of the four numbers should be 4 times the mean, which is 24. To have a mean of 6, the four numbers could be 5, 6, 7, and 6, as (5 + 6 + 7 + 6) / 4 = 24 / 4 = 6.
What number should -240 be divided to obtain 16?

How do you use number line to calculate the average of two different averages?
You cannot. It should be their weighted average with the weights representing the number of observations in each average.For example, if 3 numbers have an average of 10 and 6 numbers have an average of 20, the combined average is not the average of 10 and 20 (which is 15).It is, in fact, (3*10 + 6*20)/(3 + 6) = (30+120)/9 = 150/9 = 16.66...You cannot.
