Answer:
Step-by-step explanation:
Proportions are fractions that can be created using the numbers given. Let's pair each and reduce if possible.
Starting with 2:
2/5
2/8 = 1/4
2/20 = 1/10
Then 5:
5/2
5/8
5/20 = 1/4
Then 8:
8/2 = 4/1
8/5
8/20 = 2/5
Lastly 20:
20/2 = 10/1
20/5 = 4
20/8 = 5/2
So, we can see some are repeating, hence the unique proportions are:
2/5, 1/4, 1/10, 5/2, 5/8, 4/1, 8/5, 10/1
Answer:
1.2
Step-by-step explanation:
We have given the variance between - group estimate is = 30
And the variance within - group estimate is =25
Now we have to calculate the F ratio
F ratio is defined as the ratio of variance between the group and variance within the group
So F ratio
So for the given variance F ratio will be 1.2
Answer:
The correct option is 3.
Step-by-step explanation:
It is given that the quantities of blue and green paints used for each mix and connected them using a line segment, as shown in the graph below:
The line have two end points A(1,2) and B(9,14).
Domain is the set of inputs. In a graph all the values of x for which the graph is defined, are domain of the function.
The line is defined from x=1 to x=9. So, the domain of the function lies between 1 to 9 (inclusive).
Therefore, option 3 is correct.
