9

Step-by-step explanation:

The GCF is going to be 9

Step-by-step explanation:

When finding the GCF, you want to do prime factorization of each number.

18's prime factorization is, 2 × 3 × 3, which equals 18

36's prime factorization is 2 × 2 × 3 × 3, which equals 36

45's prime factorization is 5 × 3 × 3, which equals 45

Now all you have to do is find the factors common in each one, which is 2 three's. You then multiply 3 × 3 = 9. That is your answer

The sample should be larger to give more reliable information.

The sample size is too small to represent the population.

The sample size is too small and will show larger variation.

The sample size is too small and can lead to false inferences.
