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:
B
Step-by-step explanation:
We need to find a answer that multiplies with 4 and 6 to 192.
4 x 6 x 9 doesn't equal 192 (It equals 216)
4 x 6 x 8 does equal 192
4 x 6 x 12 doesn't equal 192 (It equals 288)
4 x 6 x 48 doesn't equal 192 (It equals 1152)
well first you could see how many words he types per min. (228/4 = 57)
so if x is the # of mins, y = 57x
good luck!
Three hundred two. You're welcome!
