47 + 5 / 2
47 - 5 = 42 (42 is the difference).
9
The arithmetic mean of 2, 5, 5, 1 and 9 is 4.4
It is: 8+8+8+5+6 = 35 and 35*5 = 7 which is the mean
Assuming the space is between the 5 and the 37, you could put 21 in there and all the numbers would be 16 apart from each other.
65.
47 - 5 = 42 (42 is the difference).
The arithmetic mean is 6.5
9
The arithmetic mean of 2, 5, 5, 1 and 9 is 4.4
The average or mean of 3, 5, 7, 9, and 11 is 7.
It is: 8+8+8+5+6 = 35 and 35*5 = 7 which is the mean
The mean of those data points is 9.
The answer depends on the arithmetic operator between 5 and 6.25 and without it, there is no way to answer the question.
The prime numbers between 45 and 55 are 47 and 53.
5
Assuming the space is between the 5 and the 37, you could put 21 in there and all the numbers would be 16 apart from each other.
