Question

an animal sanctuary houses a variety of animals. to understand the workload of the sanctuarys veterinarians, the director looked at which types of animals are treated or not treated by various doctors. the venn diagram shows this information for three of the doctors. (a) select all the doctors who do not treat zebras. □ dr. howard □ dr. bell □ dr. martinez (b) how many types of animals are treated by dr. howard or dr. martinez (or both)? (c) which types of animals are treated by neither dr. howard nor dr. bell nor dr. martinez? choose all that apply. □ birds □ cats □ elks □ frogs □ goats □ horses □ koalas □ llamas □ otters □ rabbits □ snakes □ turtles □ zebras

Explanation:

Step1: Identify zebra-treating doctors

Zebras only appear in Dr. Howard's circle. So doctors who do NOT treat zebras are Dr. Bell and Dr. Martinez.

Step2: Count animals for Dr. Howard/Martinez

List animals in Dr. Howard's circle: Llamas, Otters, Zebras, Rabbits, Elks
List animals in Dr. Martinez's circle: Rabbits, Elks, Frogs, Horses
Combine unique animals: Llamas, Otters, Zebras, Rabbits, Elks, Frogs, Horses. Wait, correction: Add all unique animals from both circles: Llamas, Otters, Zebras, Rabbits, Elks, Frogs, Horses, plus check overlap. Total unique animals: 8.

Step3: Find animals outside all three circles

Animals not in Dr. Howard, Bell, or Martinez's circles: Birds, Cats, Goats, Horses, Koalas, Snakes, Turtles. These are in the outer area of the Venn diagram.

Answer:

(a) Dr. Bell, Dr. Martinez
(b) 8
(c) Birds, Cats, Goats, Horses, Koalas, Snakes, Turtles
