Answer: .111 with a bar notation over the last 1 or 11.1%
Step-by-step explanation:
There are 12 marbles in total. There are 4 yellow marbles. Therefore there is a 4/12 probability of Randomly picking a Yellow marble the first time . Since she placed the marble back, there is a 4/12 probability of getting a yellow marble the 2nd time.
(4/12)(4/12) = 16/144 = 1/9 = .111 with a bar notation over the last 1 or 11.1% (about 11%)
3rd one 10 x 6 x 6
hope this is right
Im taking stats right now i might be able to help.
A = bh
A = (22)(18)
A = 396 m²
A = ¹/₂h(b₁ + b₂)
A = ¹/₂(8)(16 + 12)
A = ¹/₂(8)(28)
A = ¹/₂(224)
A = 112 cm²
P = 2l + 2w
20 = 2l + 2(4)
20 = 2l + 8
- 8 - 8
12 = 2l
2 2
6 = l
C = 2πr
C = 2(3.14)(8)
C = 2(25.12)
C = 50.24 in
A = πr²
A = (3.14)(3)²
A = (3.14)(9)
A = 28.26 m²
