Hello!
The objective of the veterinarian is to check if racing contributes to lameness in racing horses. To conduct a test the veterinarian should select at random two groups of horses, group one will be of racing horses and group two should be of not racing horses. Other than racing, all the other differences between the horses that may cause lame or resistance to lame should be controlled( confounding variables) such as age, breed, the number of weakly hours spent exercising, diet, obstacle-free environment, etc...
This type of study is an experimental design.
The experimental design is an analytic essay characterized by the fact that the investigator controls the study variable and the randomization of the samples. In which all the variables are controlled except the ones that you wish to study.
I hope it helps!

Answer:
The correct option is AAS.
Step-by-step explanation:
Consider the diagram below.
- It is provided that The triangles △ WXZ and △ YZX share a side <em>XZ</em>.
- Angles ∠WXZ and ∠XZY are right angles.
- Angles ∠XWZ and ∠XYZ are congruent.
If two angles are congruent it implies that they are same in degrees or radians.
So, the angles ∠XWZ and ∠XYZ are equal.
So, in the diagram below, one of the triangles have two angles that are equal to the corresponding angles on the other triangle and the two triangles share a side.
Then according to the Angle-Angle-Side (AAS) statement the triangles △ WXZ and △ YZX are congruent.
Thus, the correct option is AAS.
Math you do in your head
example you can do 10 tiemes 3=30 in your head
that is mental math
you might have a hard time doig 19 times 23 so you would use a calulator then it would not be mental math
it's helpful if at the supermarket or at a resaurant
mental math is math done in the mind
