Suppose you choose a marble from a bag containing 4 red marbles, 2 white marbles, and 3 blue marbles. You return the first marbl e to the bag and then choose again. Find P(red then blue).
1 answer:
Answer:
4/27
Step-by-step explanation:
total number of marbles=9
probability of red=4/9
since you returned the first marble, the total number of marbles remains the same
prob(Blue)=(3/9)=1/3
P(red then blue)=(4/9)*(1/3)
=4/27

Answer:
i think you have to multiply the sides..
Step-by-step explanation:
The tangent function gives the ratio of vertical to horizontal distance in this case. .. vertical distance = (horizontal distance)*tan(angle of depression) .. = (40 m)*tan(50°) .. vertical distance ≈ 47.7 m
956.25 is the answer Because 1 bottle is 212.5 grams of sugar you can just multiply that by 4.5 because there are 4 bottles and a half of a bottle
75% I think. because if you do 560 - 420 you get 140. 140 / 560 x 100 = 25 which means there is a 25% decrease, so they took 75%.
