Set T = {-3.2 , -1 , 0 , 2.5 , 4 , 6}

How many members of set $$T$$ are integers?

","type_question":"QCM","explication":"

We identify the integers in set T. Integers are whole numbers (positive, negative, or zero), no decimals or fractions.

The integers in the set are: $$-1, 0, 4, 6$$

There are $$4$$ integers in the set.

If $$m$$ is an even integer and $$m\\ne2$$, then $$m-1$$ cannot be:

","type_question":"QCM","explication":"

Since $$m$$ is an even integer, $$m-1$$ is always odd.

If $$m=15$$, then $$m-1=14$$, and 14 is not a prime number.

Since we are told $$m\\ne2$$, we must consider other even values of $$m$$.

$$m$$ can be negative and so m-1 is negative in this case.

So, m-1 could be prime, odd, possibly negative, but never zero.

The hundreds digit is the digit in the hundreds place of the whole number part:
