Why say fifteen points when it's only 5; people can see how much it's worth before even doing it.

Anyways, is there a plus in between the 2f 3 and between the -14 3?

If so, then w and k equal all real numbers and
f =   \frac{ - 1005}{22}  +  \frac{12}{11}k +  \frac{1}{11} {w}^{2} k  -  \frac{ 81}{22}  {w}^{2}
However if not, then I suggest downloading photo math and inserting it in the calculator itself to be exact.

Molly has a jar containing 4 yellow, 3 blue, 3 green, and 2 orange marbles
NeTakaya

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%)

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
