A manufacturer is testing 2 new machines for manufacturing jelly beans. Both machines have the same mean. Machine 1 has a standard deviation of 1.2 and machine 2 has a standard deviation of 5.3. Which machine should they use. Assume the cost is the same for both.

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi

i believe the answer is y=0.25x+-3
