Answer:
B) 20%
Step-by-step explanation:
Using the information given in the problem, the ratio of cats to dogs is 7:3 and the ratio of birds to dogs is 5:6. In order to find the total ratio of all three animals, you need to compare the ratios given:
Cats: Dogs is 7:3 and Birds: Dogs is 5:6
Since the ratio of Dogs increases from 3 to 6 in the two ratios, this is a factor of '2'. We would need to also increase the amount of Cats by a factor of '2' to compare all three animals: 7 x 2 = 14.
The overall ratio of all three animals is:
Cats: Birds: Dogs = 14:5:6
When we add 14 + 5 + 6 = 25, we can then take the number of birds in the ratio divided by the total number of animals to get a percent of birds at the store:

Answer:
Step-by-step explanation:
Let's arrange the numbers from least to greatest:
20, 25, 27, 28, 31, 32, 32, 38, 40, 40, 42, 48
The median is the "middle" number when arranged from least to greatest.
There are 12 numbers, so the middle number would be "average" of 6th and 7th terms.
6th term = 32
7th term = 32
Average = (32+32)/2 = 32
Hence, median = 32
Absolute deviation of 5 minutes means 5 minutes less or greater than the median, 32.
So, 32 - 5 = 27 & 32 + 5 = 37
Hence
