The level from each growth factors is an illustration of combination
There are 90 ways of combining one level from each growth factors
<h3>How to determine the number of combination</h3>
From the complete question (see attachment), we have the number of levels in each growth factor is:
- Lighting = 3
- Age = 5
- Temperature = 2
- Humidity = 3
So, the number of combination (n) is:
n = 3 * 5 * 2 * 3
n = 90
Hence, there are 90 ways of combining one level from each growth factors

Answer:
y ≈ 9.24
Step-by-step explanation:
Using the cosine ratio in the right triangle.
cos30° = =
( multiply both sides by y )
y × cos30° = 8 ( divide both sides by cos30° )
y = ≈ 9.24 ( to the nearest hundredth )
