Let the side of the square = a units, the area of the square = a^2 sq units
Area of the 4 semicircles = area of 2 circles = 2 pi r^2 = 2pi (1/2 a)^2
= pi a^2 / 2
Probability of a point in the unshaded square being picked) = area square / area of the total figure = a^2 / (a^2 * pi/2) = 1 / pi/2 = 2 /pi
which is approximately 65%
Answer: Turbo jet pack: 6d + 7; x-ray vision glasses: 2d-5; Invisible shield: 10d + 1
Step-by-step explanation:

Answer:
F = N + 2
Step-by-step explanation:
2 bases (N) + N side parallelograms (or Rectangles)
I would say to start with this equation: 20-4+3-5=14 then I would say that the absolute value is 14 or -14 I am sorry if I am wrong!
100%=all
all-change of wining=change of not winning
100%-11%=89% of not winning
probabilit is 89/100 that they dont win
