Will mark brainliest! a sample was taken of dogs at a local dog park on two random days. the counts are displayed in the table below. if there are estimated to be 50 dogs at the park at any given time, which proportion could be used to find the average number of shepherd mixes at the park at any given time?

The average number of shepherd mixes at the park at any given time is equal to .

Given the following data:

To determine the average number of shepherd mixes at the park at any given time:

First of all, we would determine the total number of shepherd mixes in sample 1 and sample 2.

Total shepherd mixes = = 16 dogs.

For the total dogs:

Total dogs = = 42 dogs.

The average number of shepherd mixes is given by this mathematical expression:

Simplifying further, we have:

Step-by-step explanation:

Let average no. of shepherds be x

there are estimated to be 50 dogs

Thus average no. of dogs /  estimated no. of dogs =x/50

Since in sample 1 there are 7 shepherd mix

In sample 2 there are 9 shepherd mix

So total shepherd mix = 9+7=16

Total dogs according to table = 4+7+3+1+2+5+9+5+2+4=42

Thus total shepherd / total dogs = 16/42
