The answer depends on which one you would like it to be:
Each one of them. 15: the only semi-prime in the list 2: the only even prime in the list 8: the only perfect cube in the list 13: the only odd prime in the list 16: the only perfect square in the list. Take your pick!
To express 15.8125 as a fraction, we can first write it as a mixed number: 15 13/16. Then, we convert the mixed number to an improper fraction by multiplying the whole number (15) by the denominator (16) and adding the numerator (13), giving us 243/16. Therefore, 15.8125 as a fraction is 243/16.
ABCDEF IS a number - in hexadecimal form. In decimal form it is equivalent to 10*16^5 + 11*16^4 + 12*16^3 + 13*16^2 + 14*16 + 15 = 11259375.
13 over 7 in a mixed number = 16/7
It is 13 and 1 over 16.
13, it's the only prime. All the other ones can be divided by something other than 1.
Take your pick: 15 because it is a product of two prime numbers 2 because it is the only even prime number 8 because it is the smallest cube that is not the same as its root (03 = 0 and 13 = 1) 13 because it is an odd prime 16 because it is a square as well as a fourth power.
18-the correct number should be 20.
One possible answer13 is the only prime number in this group Incorrect 2 is a prime number also* * * * *How about 15 as the only number having different prime factors? I admit that is tenuous, but I cannot do better.
The number is 15.
Any number not in the 13 times table. E.g 14, 15, 16,... but not 26.
There are more than one whole numbers.If you include 13 and 16, there would be 4 whole numbers, 13, 14, 15, and 16.If you do not include 13 and 16, there would be 2 whole numbers, 14 and 15.
The series 1 6 10 13 15 (1+5=6; 6+4=10, 10+3=13; 13+2=15) is completed by 15+1=16. The answer is 16.
Each one of them. 15: the only semi-prime in the list 2: the only even prime in the list 8: the only perfect cube in the list 13: the only odd prime in the list 16: the only perfect square in the list. Take your pick!
Arrange the numbers in ascending order: 7 9 9 12 13 15 16 and the middle number is the median which is 12
15 - it has 3 numbers either side of it.
13. The mode is the number or group of numbers (set) that appear most frequently in the data
