The College of Veterinary Medicine at Texas A&M University conducted a study of the rattlesnake vaccine for dogs. The researchers determined that: %0D%0A%0D%0A%0D%0A%0D%0A •12 out of 15 cases of dogs that received the vaccine prior to the rattlesnake bite survived, and%0D%0A%0D%0A •8 out of 18 cases of dogs who did not receive the vaccine prior to the rattlesnake bite survived. %0D%0A%0D%0A%0D%0AIf there were 720 dogs in the study that did not receive the vaccine and were then bitten by a rattlesnake, how many of this group survived the rattlesnake bite?

Based on the information provided:

- 8 out of 18 dogs survived the rattlesnake bite without receiving the vaccine
- This is a survival rate of 8/18 = 44.44%

If there were 720 dogs in the study that did not receive the vaccine and were then bitten by a rattlesnake, we can calculate how many of them survived by multiplying the survival rate by the total number of dogs:
44.44% * 720 = 0.4444 * 720 = 319.968

Approximately 320 of the 720 dogs that did not receive the vaccine survived the rattlesnake bite.
