Answer:
![d=\sqrt{26}\approx5.0990](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B26%7D%5Capprox5.0990)
Step-by-step explanation:
To find the distance between any two points, we can use the distance formula.
The distance formula is:
![d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28x_2-x_1%29%5E2%2B%28y_2-y_1%29%5E2%7D)
Let (2,8) be x₁ and y₁ and let (7,7) be x₂ and y₂. Thus:
![d=\sqrt{(7-2)^2+(7-8)^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%287-2%29%5E2%2B%287-8%29%5E2%7D)
Simplify:
![d=\sqrt{5^2+(-1)^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B5%5E2%2B%28-1%29%5E2%7D)
Square:
![d=\sqrt{25+1}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B25%2B1%7D)
Add:
![d=\sqrt{26}\approx5.0990](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B26%7D%5Capprox5.0990)
And that's our answer :)
Answer:
The definition of a control experiment is a test where the person conducting the test only changes one variable at a time in order to isolate the results. An experiment where all subjects involved in the experiment are treated exactly the same except for one deviation is an example of a control experiment.
