Answer:
A) 7
B) 32
C) 39
Step-by-step explanation:
Degree of freedom is a means of checking how many values that are free to vary, while using a statistical method.
a) since the experiment has a single factor with eight critical values. Therefore;
C - F = degree of freedom among the group variation
8 - 1 = 7
b) The degree of freedom can be calculated, if the number of data; Therefore, number of data is;
N = 8 × 5 = 40
Then the degree of freedom in determining within group variation,
N - C Therefore;
40 - 8 = 32
C) The degree of freedom in determining the total variation is,
N - 1
40 - 1 = 39
Step-by-step explanation:
For x = 7 or y = f(7)
Graph and solution are in the picture below
It is 1,998 bigger than 2.
Answer:
The higher you go in the good chain the lower the population.
Explanation:
In the food web, there are only a few sharks since in the food chain they are higher. Just 10% energy is retained in the tissues once the energy is moved from one trophic level to another, and the leftover power is emitted as metabolic energy.
If an animal is high up the energy ladder, the individual has less resources; thus, a few of the highest predators are present in an ecosystem.
Answer:
x=17/4
Step-by-step explanation:
(x-3)/(x+2)=1/5
cross product
1(x+2)=5(x-3)
x+2=5x-15
5x-x-15=2
4x-15=2
4x=2+15
4x=17
x=17/4
