Answer:
The experimental subjects are pine tree seedlings .
Step-by-step explanation:
The physical entity to which the treatment is assigned at random is known as experimental unit .
The same treatment cannot be received by two experimental units, they have to different treatments. The selection of experimental units plays an important role to determine the p-values in the statistical analysis. The experimental units are divided into different homogeneous groups called blocks.
From the question, the experimental subjects identified are pine tree seedlings.
Answer:
B. 
Step-by-step explanation:
First, find the <em>rate of change</em> [<em>slope</em>]:


Then use the Slope-Intercept Formula instead of the <em>Point-Slope Formula</em> because you get it done faster that way. It does not matter which ordered pair you choose:
−9 = 3 + b
−12 = b

________________________________________________________________________________________________
−5 = 7 + b
−12 = b

** You see? I told you it did not matter which ordered pair you choose because you will ALWAYS get the exact same result.

Answer:
x = 6 cm
Step-by-step explanation:
The area (A) of a triangle is calculated as
A =
bh ( b is the base and h the height )
Here b = 12 and h = 4, then
A =
× 12 × 4 = 6 × 4 = 24 cm²
Then area of parallelogram = 3 × 24 = 72 cm²
The area (A) of a parallelogram is calculated as
A = bh ( b is the width and h the height )
Here b = x and h = 12, thus
12x = 72 ( divide both sides by 12 )
x = 6
The width of the parallelogram is 6 cm
-3x -3 < -63 subtract the 3 first
-3x < -60 then divide the -3 from both sides
x < 20 is your answer
