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!

Step-by-step explanation:
Area of two circles = 2*πr² = 2*3.14 * 6 * 6 = 226.08 square units
Area of rectangle = length * width = 24 * 12 = 288 square units
Area of shaded region = Area of rectangle - area of two circles
= 288 - 226.08
= 61.92
= 62 square units
Answer:
44 + 45 = 99° divided by 2 = 49.5 (you can round to 49)
The width of the rectangle is A. 4 inches
