A. What is the mean age of the dogs at the park? c. what is the median age of the dogs at the park?

Mean: 4.9 Median: 4

Step-by-step explanation:

For the mean you add all of the numbers up and divide it by how many numbers there are in total,for this case it's 29 and you should get 4.9 when you round it by the nearest tenth.

For the median you write all of the numbers from least to greatest and cross out the numbers from Left to right. If you had an even number then it would have two numbers, but in this case it has a odd amount of numbers so it should only have one number in the middle, and that number that's left should be the answer.
