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.)

Recall that tanA = sinA / cosA.
Therefore, tanA = (3/5) / (4/5) = 3/4.
Answer:

Step-by-step explanation:
Swap the sides of the inequality and flip the inequality sign:

Divide both side of the inequality by -6 and flip the inequality sign:

Answer:
the answer is 672
Step-by-step explanation:
420 × 60% = 252
420 + 252=672
625 is the total number of learners
