Let C be the number of cats and B be the number of birds.
Each cat has 4 legs while each bird has 2 legs. Thus,
4C + 2B = 22
2B = 22 - 4C
Each cat and each bird has 2 eyes
2C + 2B = 16
Substituting 2B
2C + 22 - 4C = 16
2C = 6
C = 3
2B = 22 - 4(3)
B = 5
2 cats and 5 birds
The mean of 357.5 depends on how many numbers there are to begin with. Ex: if there is 5 and all 5 then divide it by 5.
Answer:
The mean is 104 (Just add them all up)
The median is either 6 or 10 (its the number in the middle, sometimes there are two medians)
The mode is 15 (It shows up more than once)
The range is 13 (Take the smallest number and the highest number and subtract)
Here is the answer:
n+n+1+n+2
=3n+3. Hope it help!
