For an analysis of variance, if the between-group estimate of the population variance is 30, and the within-group estimate is 25
borishaifa [10]

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 =\frac{30}{25}=1.2

So for the given variance F ratio will be 1.2

Ivahew [28]
So here are the answers to the given questions above:
1. Since the equation is already given, what we are going to do is to solve for x first. 
<span>x + (2x – 10) + 1/2 (2x – 10) = 145
x + (2x -10) + x - 5 = 145
x + 2x + x - 10 - 5 = 145
4x = 145 +10 + 5
4x = 160 <<divide both sides by 4 and we get
x = 40.
Therefore, the amount of white paint is 40ml.
The amount of blue paint is 70ml and the green paint is 35ml.
So the difference between the a</span><span>mounts of white paint and blue paint Vivian combined is 30ml.
2. T</span>he equation of the line that passes through the points (-2, 1) and (1, 10) would be: <span>3x - y = -7, the last option. In order to check, just plug in the given ordered pairs.</span>

Let us set up some variabe:

  • height: h
  • base: b

Use the known information:

  • b = 2h + 8

Now lets find the area

   Area = (1/2) * b *h = (1/2) * h * (2h + 8)

Hope that helps!
