The answer would be $1.80. 25% off of $3.00 is $2.25 and 20% off that is $1.80

The answer is $1.80.  You would take 25% of 3, which is 75, and subtract it from 3.  That leaves you with $2.25, which you take 20% off, which is 0.45, and subtract that from 2.25.  That leaves you with a grand total of $1.80.  Hope that this helped!

A rectangle on a coordinate plane has vertices L(0.6), M3, 6), N80), and O(0, 0) What are the dimensions of the
Julli [10]

Answer:

• The base is 8 and the height is 6

Step-by-step explanation:

A rectangle has two dimensions:

The base, which is the distance between the points who have the same value of y.

The height, which is the distance between the points who have the same value of x.

Distance between 2 points:

Points (a,b) and (c,d).

D = \sqrt{(c-a)^{2} + (d-b)^{2}}

I suppose there was a small typing mistake, as these points do not make a rectangle.

I will say that we have these following points:

L(0,6), M(8,6), N(8,0), O(0,0).

Base:

Same value of y.

L(0,6), M(8,6), or N(8,0) and O(0,0).

They will have the same result, will use the second.

D = \sqrt{(8-0)^{2} + (0-0)^{2}} = \sqrt{64} = 8

The base is 8.

Height:

Same value of x.

L(0,6), O(0,0) or M(8,6) and N(8,0).

D = \sqrt{(8-8)^{2} + (6-0)^{2}} = \sqrt{36} = 6

The height is 6.

So the correct answer is:

• The base is 8 and the height is 6

The null hypothesis in ANOVA is that all means of all groups are the same. The alternative is that at least one pair of means is
d1i1m1o1n [39]

Answer:

Correct option: B. Less between group variability

Step-by-step explanation:

The Analysis of Variance (ANOVA) test is performed to determine whether there is a significant difference between the different group mean.

The hypothesis is defined as:

<em>H₀</em>: There is no difference between the group means, i.e. <em>μ</em>₁ = <em>μ</em>₂ = ... = <em>μ</em>ₙ

<em>Hₐ</em>: At least one of the mean is different from the others, i.e. <em>μ</em>_{i} ≠ 0.

The test statistic is defined as:

F=\frac{SS_{between}}{SS_{within}}

If the null hypothesis is true then the test statistic will be small and if it is false then the test statistic will be large.

In this case it is provided that the null hypothesis is true.

This implies that:

SS_{between}

Implying that the sum of squares for between group variability is less than within group variability.

Thus, if the null hypothesis is true there will be less between group variability.
