Answer:
perimeter= 40.8
area= 333.3
Step-by-step explanation:
a^2 + b^2 = c^2
9^2 + 7^2 = get the answer then find the square root of it
Answer:

For this case we can conclude that with 98% of confidence the true proportion of Drosophila in a population would be between 0.34 and 0.38.
But that doesn't means that we have 98% of PROBABILITY that the true proportion would be between 0.34 and 0.38, because we are constructing a confidence interval with sample data and we can't analyze this using probability.
Then the best answer is:
2. False
Step-by-step explanation:

Answer:

Step-by-step explanation:









Therefore,
Pam and her brother both open savings accounts. Each begin with a balance of zero dollars. For every two dollars that Pam saves in her account, her brother saves five dollars in his account.
1. Determine a ratio to describe the money in Pam’s account to the money in her brother’s account. :
2. If Pam has dollars in her account, how much money does her brother have in his account? Use a tape diagram to support your answer.
Pam’s brother has dollars in his account.
3. Record the equivalent ratio. :
4. Create another possible ratio that describes the relationship between the amount of money in Pam’s account and the amount of money in her brother’s account. Answers will vary. :, :, etc.
I hope I helped! :)
