Phrasing Flashcards
N had exactly two factors
N is a prime
N has an odd number of factors
N is a perfect square
K is an x-intercept of the function F(x)
F(K) = 0
K is a y-intercept of the function
F(x)
F(0) = K
K is a multiple of N
N is a factor of K
N is a divisor of K
X^2 is an integer
Don’t know much…x could equal 2 or root(2)
Sqrt(x) = integer
X is an integer and perfect square
A two digit number has it’s digits reversed
If the number is AB, it used to equal 10A + B. Now it is equal to 10B + A.
Implications: difference = 9A - 9B (always a multiple of 9)
Sum = 11A + 11B (always a multiple of 11)
Product of two integers is odd
Both integers are odd
Product of two integers is even
At least one of the integers is even
The average of N numbers is equal to K
The sum of the N numbers is NK
Set A consists of evenly spaced numbers
The mean and median of set A are equal
The mean and median of Set A are equal
CANNOT conclude that Set A consists of evenly spaced numbers
What are non zero digits?
1,2,3,4,5,6,7,8,9
When x is divided by 2 the remainder is 1.
X is odd
