Answer:
30/169
Step-by-step explanation:
We need to know how many marbles in the bag
6 red marbles + 2 white marbles + 5 blue marbles = 13 marbles
P (red) = red / total = 6/13
We then put the marble bad so there are still 13 marbles in the bag
P(blue) = blue /total = 5/13
P (red then blue ) = P(red) *P(blue)
= 6/13 * 5/13 = 30/169
Answer:
y=3x-4
Step-by-step explanation:
slope = 3
(y-5) = 3(x-3)
y-5 = 3x-9
y-5+5=3x-9+5
y=3x-4
Answer:
1 5/14
Step-by-step explanation:
-3 1/6 / -2 1/3
-3 1/6 = -19/6
-2 1/3 = -7/3
-19/6 / -7/3 = -19/6 x -3/7
-19 x -3 = 57
-6 x -7 = 42
57/42 = 1 5/14
Answer:
car covers distance of 450 km in 4hr and 30min
4hr and 30 min - (4*60)+ 30 equal to 270
distance covered by car in one minute equal to 450/270 equal to 1.6 km
speed of car equal to (1.6*60)/60 equal to 1.6 km /hr
