growth of a particular type of plant. He is testing the effects of four growth factors: lighting, age, temperature, and humidity
GREYUIT [131]

The level of each growth factor is an illustration of a combination

There are 90 ways of combining one level from each growth factors

<h3>How to determine the number of combinations?</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 factor.

Plz help me :(<br> Oof ;-;
nirvana33 [79]

Answer:

6. I know that Christine hiked the Evergeen trail twice and the Yellow River trail once. I also know that Brian hiked the three longest trails once. I am asked to find how many more miles did Brian hike than Christine. I do not need to know that the family is staying at the state park for a week.

7. I need to find out how many miles Christine hiked and how many miles Brian hiked.

8. C = Christine's total

   B = Brian's total

(4 3/4 x 2) + 5 1/4 = C

6 + 5 1/4 + 4 3/4 = B

9. (4 3/4 x 2) + 5 1/4

    (19/4 x 2) + 5 1/4

    19/2 + 5 1/4

     9 1/2 + 5 1/4

      C = 14 3/4

  6 + 5 1/4 + 4 3/4

  5 4/4 + 5 1/4 + 4 3/4

      <u> </u>B = 16

   <u> </u>16 - 14 3/4 <u>= 5 1/2</u>

10. It makes sense because Brian three of the longest trails while Christine didn't
