The College of Veterinary Medicine at Texas A&M University conducted a study of the rattlesnake vaccine for dogs. The researchers determined that:
•12 out of 15 cases of dogs that received the vaccine prior to the rattlesnake bite survived, and
•8 out of 18 cases of dogs who did not receive the vaccine prior to the rattlesnake bite survived.
If there were 900 dogs in the study that received the vaccine and were then bitten by a rattlesnake, how many of this group did NOT survive the rattlesnake bite?
Responses
A 720720
B 400400
C 180180
D 500
To find the number of dogs in the group that did not survive the rattlesnake bite, we need to subtract the number of dogs that did survive from the total number of dogs in the group.
Out of the 900 dogs in the group, 12 survived. Therefore, 900 - 12 = 888 dogs did not survive the rattlesnake bite.
Therefore, the answer is A) 720720
