<u>Answer:</u>
The probability of getting two good coils when two coils are randomly selected if the first selection is replaced before the second is made is 0.7744
<u>Solution:</u>
Total number of coils = number of good coils + defective coils = 88 + 12 = 100
p(getting two good coils for two selection) = p( getting 2 good coils for first selection ) p(getting 2 good coils for second selection)
p(first selection) = p(second selection) =
Hence, p(getting 2 good coil for two selection) =
Answer:
2102.13 mm^2
Attached is a completed image of the question
Step-by-step explanation:
Given;
Radius of the circle r = KL = 27.1 mm
Angle of unshaded region = 32°
The total angle in a circle is 360°
Angle of shaded region θ = 360° - angle of unshaded region.
θ = 360° - 32° = 328°
The Area of a circle = πr^2
Area of shaded region A = (θ/360)πr^2
Substituting the given values;
A = (328/360)×π × 27.1^2
Area of shaded region A = 2102.13 mm^2
