Felipe is studying the growth of a particular type of plant he is testing the effects of three growth factors lighting age and temperature here are the levels he's testing for each

Lighting: none, low, medium, high, very high
Age: 1 month, 2 months, 3 months, 4 months, 5 months, 6 months
Temp: 20°C, 22°C

He wants to find the number of ways of combining one level from each of the growth factors how many are there

To find the number of ways of combining one level from each growth factor, we simply need to multiply the number of levels for each growth factor.

Lighting has 5 levels: none, low, medium, high, very high.
Age has 6 levels: 1 month, 2 months, 3 months, 4 months, 5 months, 6 months.
Temp has 2 levels: 20°C, 22°C.

Therefore, the number of ways of combining one level from each growth factor is:
5 (lighting levels) * 6 (age levels) * 2 (temperature levels) = 60.

To find the number of ways of combining one level from each of the growth factors, we need to use the concept of permutations.

First, we need to determine the number of levels for each factor:

- Lighting: 5 levels (none, low, medium, high, very high)
- Age: 6 levels (1 month, 2 months, 3 months, 4 months, 5 months, 6 months)
- Temperature: 2 levels (20°C, 22°C)

To calculate the total number of combinations, multiply the number of levels for each factor:

5 (lighting) x 6 (age) x 2 (temperature)

Therefore, there are 60 ways of combining one level from each of the growth factors.

To find the number of ways of combining one level from each of the growth factors, we can use the concept of combinations.

The number of combinations can be found by multiplying the number of levels for each growth factor.

In this case, the number of levels for lighting is 5 (none, low, medium, high, very high), the number of levels for age is 6 (1 month, 2 months, 3 months, 4 months, 5 months, 6 months), and the number of levels for temperature is 2 (20°C, 22°C).

Therefore, the total number of ways to combine one level from each growth factor is calculated as:

5 (number of levels for lighting) * 6 (number of levels for age) * 2 (number of levels for temperature) = 60

So, there are 60 ways of combining one level from each of the growth factors.
