A jar of marbles contains 9 red marbles, 5 blue marbles, 3 pink marbles, 2 yellow
marbles, and 1 purple marble. A marble
will be drawn from the bag and replaced
50 times. What is a reasonable
prediction for the number a times a pink
or purple marble will be drawn?

answer: 5100 just subtract

step-by-step explanation:

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
