Answer:
-1
Step-by-step explanation:
The mean is the sum of all values divided by the amount of values.
We take the sum of all the numbers:
-3 + -8 + 12 + -15 + 9
-11 + 12 + -15 + 9
1 + -15 + 9
10 + -15
-5
We then divide the sum by how many number we have (we are given 5 numbers):
-5/5 = -1
Therefore, our mean is equal to -1.
12 dogs to 92 cats.
12/92
Both 12 and 92 are divisible by 4.
12/4=3
92/4=23
Simplified ratio: 3/23
There are 3 dogs for every 23 cats.
