Answer:
132 in^2 but DOUBLE CHECK MY WORK!!!!
Step-by-step explanation:
Break it down into parts ok. So I see a 10x10 square, two 2x4 right triangles and a 4x6 rectangle.
10x10 is 100 in
1/2(2*4) = 4 x 2 = 8 in
6x4 = 24 in
add them together to get 132 in^2
Answer:
25 times
Explanation:
Blue Marvels: 3
Red Marvels: 5
Total Marvels: 5 + 3 = 8 marvels
Probability: favorable outcomes/total outcomes
Probability - red marble = 5/8
After Doing 40 times:
= 5/8 × 40
= 25
P(defective) = 3/12 = 1/4
P(good) = 1 - 1/4 = 3/4



The probability that at least 2 units are good is given by:
P(2 good) + P(3 good) + P(4 good) = 0.211 + 0.422 + 0.316 = 0.949.
Since it has a half life of 60 days, this means that every 60 days it multiplies by 0.5. Since it asks for 300 days, your equation is 500*(0.5)^5, which is 15.625 mg left after 300 days.
