Ecosystem includes all of the biotic and abiotic factors that are found in a given environment. Biome is a collection of different ecosystems which share similar climate conditions.
Answer:
2.57
Explanation:
Given the data:
X : 17, 17, 16, 17, 23, 22, 21
Mean absolute deviation (MAD) :
Σ|x - xbar| ÷ n
xbar = Σx/ n
n = 7
Σx = (17 + 17 + 16 + 17 + 23 + 22 + 21) = 8
xbar = 133/7 = 19
|x - xbar| :
|17 - 19|= 2
|17 - 19| = 2
|16 - 19| = 3
|17 - 19| = 2
|23 - 19| = 4
|22 - 19| = 3
|21 - 19| = 2
Therefore,
MAD = (2+2+3+2+4+3+2) / 7
MAD = 18 / 7
MAD = 2.57
Answer:
False
Explanation:
Suburban communities are NOT generally more populous and densely built than urban areas.
If it doesn't have a variable above the Y or X
Selective cutting would best meet these two goals.
<u>Explanation:</u>
Selective cutting can be the best logging technique to harvest the timber more sustainably. This method is less damaging as compared to the clear-cutting method. This technique is costly as compared to the clear-cutting technique.
It enables the cutting of a few economically valuable trees. The other trees which are not economically valuable need not to cut. It causes less loss to the environment and protects nature. Conservation of the environment is the focus of this technique.
