Answer:
35/68
Step-by-step explanation:
The first box contains 3 orange balls and 4 black balls.
The second box contains 5 orange balls and 6 black balls
Total number of boxes = 2
Let Pr(F) be the probability that the first box is picked.
Let Pr(S) be the probability that the second ball is picked
Let O be the orange ball selected
Pr(F) = 1/2
Pr(S) = 1/2
Pr(O|S) = n(O) / n(S)
= 5/ 6+5
5/11
Pr(O|F) = n(O) / n(F)
= 3/ 4+3
= 3/7
Pr(S|O) = [Pr( O|S).P(S)] / [Pr( O|S).P(S) + Pr( O|F).P(F)]
= (5/11*1/2) / (5/11*1/2) +(3/7*1/2(
= (5/22) / (5/22 + 3/14)
= (5/22) / (136/308)
= 35/68

<span>A regular hexagon is defined as a hexagon that is both equilateral and equiangular. It is bicentric, meaning that it is both cyclic (has a circumscribed circle) and tangential (has an inscribed circle).
The common length of the sides equals the radius of the circumscribed circle, which equals {\displaystyle {\tfrac {2}{\sqrt {3}}}} {\displaystyle {\tfrac {2}{\sqrt {3}}}} times the apothem (radius of the inscribed circle). All internal angles are 120 degrees. A regular hexagon has 6 rotational symmetries (rotational symmetry of order six) and 6 reflection symmetries (six lines of symmetry</span>

54 divided by 3 equals 18.
18 times 2 equals 36.

Answer:
1. x = +/- 2
- 7
2. x = 
+/- 
3. n = 
+/- 
Step-by-step explanation:
1. Divide both sides by 2: (x + 7)^2 = 8
Square root both sides: x + 7 = +/- 2
Subtract 7 from both sides: x = +/- 2 - 7
2. Square root both sides: x - 3 = 
Since there is a negative inside the radical, we need to have an imaginary number: 
. So, 
Add 3 to both sides: x = +/-
3. Divide by -5 from both sides: (n - 2)^2 = -2
Square root both sides: n - 2 = 
Again, we have to use i: 
Add 2 to both sides: n = +/-
Hope this helps!
12 x 8 = 96
96/2 = 48
it's an area equation so 48 m^2
