The mode for this set of numbers is 18 because there are three 18's in the set of number, and only two 20's. :D

Mode is just the number that occurs most often.

<span>18, 15, 16, 18, 20, 17, 14, 17, 18, 20
</span>
17.5 and 17.3 never occur. 18 occurs 3 times. 20 occurs twice.

So 18

Calculate 6+9i/-1+4i
lisabon 2012 [21]

Multiply the numerator and denominator by the conjugate of the denominator:

\dfrac{6+9i}{-1+4i} \times \dfrac{-1-4i}{-1-4i} = \dfrac{(6+9i)(-1-4i)}{(-1)^2-(4i)^2}

Simplify:

\dfrac{(6+9i)(-1-4i)}{(-1)^2-(4i)^2} = \dfrac{-6-9i-24i-36i^2}{1-16i^2} = \dfrac{-6-33i-36i^2}{1-16i^2} = \dfrac{-6-33i+36}{1+16} = \boxed{\dfrac{30-33i}{17}}
