Which statement is NOT true about the number 0x9 equals 0 A. 0 is a factor B. 9 is a factor C 0 is the product D. 9 is the only factor?
D is the choice that is not true.
Is the gcf of an odd and even number always even?
No. The opposite is true: the gcf of an odd number and an even number is always odd. All the factors of an odd number are odd; or to put it another way: If a number has an even factor, the number itself must be even. Thus the only common factors between odd and even numbers must be odd.
The rank of product of two matrices cannot exceed the rank of either factor?
The statement that the rank of product of two matrices cannot exceed the rank of either factor is a true statement. The rank of a matrix is the largest number of linearly independent rows or columns. The column rank is equal to the row rank in every matrix.
Is it true or false that any number that divides another number with a remainder of 2 is called a factor?
False. Factors divide evenly with no remainder.
What conjecture must be true about the least common multiple of any number pairs in which one number is the greatest common factor of the other number?
Given a pair of numbers, if the lesser of the two is the GCF, the greater of the two is the LCM. This happens when one of the numbers is a factor of the other.
Is it true that a prime number is a whole number greater than 1 that has only itself and 1 as a factor?
It is true.
Is every number a factor of itself?
it is true because a factor of a number is a number that divides the supplied number perfectly with no remainders. This includes the actual number. For instance, consider the number 14. The digits 1, 2, 7, and 14 are 14 factors.
The GCF of a group of natural numbers the largest number that is a factor of all the numbers in a group?
Yes, that is true.
Which is a true statement about number 1?
The integer 1 is a whole number that is neither a prime or a composite number because it has only one factor which is itself.
What must be true for a number to be described as composite?
It must have at least one more factor in addition to '1' and itself.
The largest amount of a population that can be supported by an are is limiting factor true or false?
the largest amount of a population that can be supported by an are is its limiting factor
Is every number a factor of 1 true or false?
As stated, that is false. Every number is not a factor of 1. 1 is a factor of every nonzero whole number.
Is it true that one is a factor of every prime number?
Yes, that is the definition of a prime number, having only two possible factors, one and the prime number itself.
Does any number that has a 2 as a factor have a 4 as a factor?
No; this statement is not true. The number 6 is an example of why this is not true.
Is the only factor greater than half itself?
That's true.
Is it true that the only factor greater than half is itself?
Yes.
Does any number that has 7 as a factor also have 2 as a factor and why?
No, this statement is not true. 21 is an example of why this is not true.
