Applications of Probability Project: Zombie Apocalypse Adapted from "Are You Positive?" Learning Task in the Georgia Frameworks

Zombies are on the loose! A group of researchers wants to be able to detect those who have contracted the zombie virus before they turn into zombies. Those who test positive will be quarantined for two weeks. If they show no signs of being a zombie, they will be freed. They have developed a simple test where they swab the person's ear (mouth would be too dangerous). They gathered 200 people of which 50 were known to be have the zombie virus. Of those who had the virus, 48 tested positive. Of those who did not have the virus, 135 tested negative 1. Based on the data presented above, do you think the test for zombieism is effective at detecting future zombies. Why or why not?

Answer:

Yes, it is a very effective test, having almost a 100% detection rate you wouldn't need much to improve upon except testing multiple times.

Billy is constructing a garden divided into 8 equal sections. The diameter of the garden is 12 feet. What is the area, in square
pishuonlain [190]

If the diameter of the garden is 12 ft, then the radius is 6 ft.

The area is then π(6 ft)^2, or 36 ft^2.

Then the area of one of the 8 equal sections of the garden is 36/8 ft^2, or 9/2 ft^2, or 4.5 ft^2.

Answer:

Option A.

Step-by-step explanation:

1. BC ║ ED    [Given}

2. m∠ABC = 70° [Given}

3. m∠CED = 30°  [Given]

4. m∠ABC = m∠BED [Corresponding angle theorem]

5. m∠BEC + m∠CED = m∠BED [Angle addition postulate]

6. m∠BEC + 30° = 70° [Substitution property of equality]

7. ∠BEC = 40° [Subtraction property of equality]

Therefore, option A is the answer.
