Answer: There are 9 possible treatments .

Step-by-step explanation:

There are 3 different baking temperatures (350, 400 and 450) and 3 different baking times (45 minutes, 55 minutes and 60 minutes).

By Fundamental counting principle,

Number of treatments  = (Number of different baking temperatures) x (Number of different baking  times)

= 3 x 3 = 9

Hence, there are 9 possible treatments .

The number of treatments is 9.

Given that,

  • You will test the recipe with 3 different baking temperatures (350, 400 and 450) and 3 different baking times (45 minutes, 55 minutes and 60 minutes).

Based on the above information, the calculation is as follows:

Here we used the fundamental counting principle.  

[tex]= 3 \times 3 \\\\= 9[/tex]

Therefore we can conclude that the number of treatments is 9.
