First, note the number of tiles in each color. So there are 6 black tiles and 9 white tiles.
The probability of picking a black tile the first time is 6/15 which is equal to
2/5
Now, with black tile gone there are 5 black tiles and 9 white tiles.
The probability of picking a black tile now is
5/14.
But because both picks have to happen, multiply the fractions resulting in
1/7
Answer: 10x+9=320 || if you’re looking for the missing number you have to solve for x so move the nine over 10x=320-9, 10x=311, x=31.1
I think the answer is 240 :)
Answer:
AREA is 9 to the power of 4
Step-by-step explanation:
Which is 9×9×9×9= the answer
Cause area = l×w×h
9514 1404 393
Answer:
3 1/3
Step-by-step explanation:
Multiply both sides by the reciprocal of the coefficient of c.
(5/2c)(2/5) = (8 1/3)(2/5)
c = (25/3)(2/5) = 50/(3·5) = 10/3
c = 10/3 = 3 1/3
