Vineet can conclude that:
B ) the system of equations does not have a solution.
It is given that the weight of the barbel is given by:

It says that there are eight pair of weights so x can take values from 0 to 8 and f(x) can take the values as follows:

So the range is:

Option B is correct.
0.009 because whenever you multiply a decimal by 10, 100, 1000, 10000 etc. you move the decimal to the right however may zeros are in the number. EXAMPLE:
