The "relative frequency" is

         (number of times a blue marble came out)
divided by
         (total number of trials before everybody got bored and quit) .

-- The relative frequency of blue was  (20/60)  =  (33 and 1/3) % .
(Even though 38.5% of the marbles in the jar are blue,
they didn't get picked that often.)

-- The relative frequency of green was  (18/60)  =  30 % .
(Even though only 26.9% of the marbles in the jar are green,
they got picked more often than that.)

-- The relative frequency of red was  (22/60)  =  (36 and 2/3) % .
(Even though 42.3% of the marbles in the jar are red,
they didn't get picked that often.)

Use the Factor Theorem to find ALL zeros of f(x) = x^3 - x^2 - 11x + 15, given that 3 is a zero. Show all work and express zeros
ELEN [110]

Answer:

Step-by-step explanation:

by synthetic division

3) 1   -1   -11    15

|       3     6   -15   (add)

____________

   1     2    -5 |0

x²+2x-5=0

x=\frac{-2 \pm\sqrt{2^{2} -4*1*-5} }{2*1} \\or~x=\frac{-2 \pm\sqrt{4+20} }{2} \\or~x=\frac{-2 \pm2\sqrt{6} }{2} \\or ~x=-1 \pm \sqrt{6}
