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".
Hello!
To solve this you look at one point of the smaller rectangle
A point of the smaller rectangle is (3, 1)
Now we look at the corresponding point of the larger rectangle
The corresponding point is (6, 2)
Now we look at what happened between the points
They doubled both x and y
This can be written as (2x , 2y)
The answer is D) (2x , 2y)
Hope this helps!
We can say that the area of the figure equals...
5.5 by 9 rectangle - 2 by 2 triangle - 2 by 5 triangle - 9 by 3.5 triangle
5.5 by 9 rectangle = 5.5 x 9 = 49.5 un²
2 by 2 triangle = 1/2 x 2 x 2 = 2 un²
2 by 5 triangle = 1/2 x 2 x 5 = 5 un²
9 by 3.5 triangle = 1/2 x 9 x 3.5 = 15.75 un²
area of figure = 49.5 un² - 2 un² - 5 un² - 15.75 un² = 26.75 un²
answer: 26.75 un²
I assume C. The other options don’t make sense. So my answer would be C:
11 = 8 + 3
Sorry if I’m wrong.
