Well, mode means most frequent number within the set so since there is two 18's that is your mode.
Answer:
Step-by-step explanation:
"4x2 – 3x + StartFraction 2 Over x EndFraction" is definitely not a polynomial because one of the exponents of x is negative.
"–6x3 + x2 – StartRoot 5 EndRoot" is a polynomial because all of the exponents of x are integers 0 or greater.
The presence of any root (fractional exponents included) of the variable x automatically disqualifies such expression: it's not a polynomial.
Answer: 15 meters
Step-by-step explanation:
1cm/4m= X cm/ 60 m
Cross multipsy
4x=60
Divide by 4
X=15

notice, the inverse set is just, the same set with the x,y turned to y,x, backwards.
is it a one-to-one? well, for a set to be a one-to-one, it must not have any x-repeats, that is, the value of the first in the pairs must not repeat, and it also must not have any y-repeats, namely the value of the second in the pairs must not repeat.
$9.96 is the answer to the question
