Answer:
x = 6
Step-by-step explanation:
First, separate the problem into 
Then, Subtract 9 from both sides of the equation. 
Simplify. 
Multiply 3 to each side, which will give you -2x = 4x - 36
Subtract 4x from each side -2x - 4x = 4x - 36x - 4x
Combine like terms: -6x = -36
Divide both sides by -6
Your answer should be 6
<em>(sorry for the late answer)</em>
PLUG in the numbers
4.5=500 x R x 2.5
divide both sides by 500
0.009=R x 2.5
divide 2.2 to both sides
R=.0036
In percent you have to multiply by 100 which is 0.36%

Answer:
Step-by-step explanation:
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!
