Answer:

Step-by-step explanation:
<em>Look at the picture.</em>
We have
square with side length a = 9
trapezoid with base lengths b₁ = 9 and b₂ = 6 and the height length h = 6
right triangle with legs lengths l₁ = 3 + 6 = 9 and l₂ = 6
The formula of an area of a square

Substitute:

Answer:
a. The mean growth of plant is same for each type of soil.
Step-by-step explanation:
The analysis of variance is statistical procedure used to assess the equality of more than two means by computing two different estimate of variances. Basically when we have more than two means to compare, we can't use t-test or z-test because these procedure will be tedious and time taking. So, the null hypothesis will be the same. Hence the null hypothesis in the given scenario is that "the mean growth of plant is same for each type of soil".
Answer:
y=-4x-14
Step-by-step explanation:
Lines that are parallel would have the same slope, so the slope is
m= -4
Use point slope equation to solve for the slope intercept equation.
y-y1=m(x-x1)
m= -4
x= -3
y= -2
y-(-2)=-4(x-(-3))
y+2=-4x-12
y=-4x-14
