Answer:
0.095 or 9.5%
Step-by-step explanation:
Puncture → P(P) = 0.06
Smashed corner → P(S) = 0.04
Puncture and smashed corner → P(P and S) = 0.005
The probability that a randomly selected carton has a puncture or a smashed corner is given by the probability of a puncture, added to the probability of a smashed corner, subtracted by the probability of both:
The probability is 0.095 or 9.5%.
Solving the inequality for the number of boxes Michelle can take into the elevator:
so the solution set is x<=52 with a closed circle on 52.
The following are the applicable choices from your list (all at the same true):
"There is a closed circle on 52"
"The solution set contains the point 51"
"The arrow points to the left"
1.
Area of shaded region,
=(Area of bigger circle) - (Area of smaller circle)
=πR^2 - πr^2
=π ( R^2 - r^2 )
=3.14 ( 8^2 - 4^2)
=3.14 × ( 64 - 16 )
=3.14 × 48
=150.72 cm^2
2.
Area of shaded region,
=(Area of big semi-circle) - ( Area of small semi-circle)
=(πR^2)/2 - (πr^2)/2
=π/2 ( R^2 - r^2 )
=3.14/2 ( 6^2 - 3^2 )
=1.57 × ( 36 - 9 )
=1.57 × 27
=42.39 cm^2
