You are conducting an experiment to test the density of a new recipe for chocolate cake. 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). How many treatments are there?

The number of treatments is 9.

Given that,

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

Here we used the fundamental counting principle.  

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

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 .

okay so 15.15 *()5: +5/6

step-by-step explanation:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
