I'm not too sure on this can i have some help
Ganezh [65]
Welcome to Brainly. We are here to help! 

Similar polygons vary directly with each other. They have the same scale.

Something I notice about the polygons is that both of the sides are decreased by 10.

40-30= 10 and 28-18=10

Try to find the scale.

40/28= 1.42857....

30/18= 1.666666777


I would say these are not similar polygons. They do not share the same scale.

I hope this helps!

<h3>Explain ANOVA test:</h3>

The ANOVA test permits an examination of multiple gatherings simultaneously to decide if a relationship exists between them.

<h3 /><h3>According to question:</h3>

We ought to utilize ANOVA rather than a few t-tests to assess the distinctions in the mean of at least three gatherings on the grounds that without fail, we direct a t-test (between two gatherings) there is some opportunity that a Kind I blunder is being made while doing the test.
