The Option A best explains the dual experiments: "In the experimental group, a chosen variable is altered in a known way. In the control group, that chosen variable is not altered so a comparison can be made."
<h3>What is experimental design?</h3>
- The process of deciding which variables to use in an experiment to test a particular hypothesis is called experimental design.
- To properly collect data and evaluate the hypothesis, the experimental design method is used.
Now,
- A specified variable is changed in the experimental group in a well-known fashion.
- That selected variable is left unaltered in the control group so that comparisons can be conducted.
- Control variables are variables that are utilized in an experiment to serve as a baseline against which the data from the experimental variables are gathered and evaluated (which is why the other answers are incorrect).
- In the experimental group, it is advisable to modify just one variable at a time so that any differences from the control group may be quickly linked to the one variable that was altered.
Hence, amongst all the given options, The Option A best explains the dual experiments: "In the experimental group, a chosen variable is altered in a known way. In the control group, that chosen variable is not altered so a comparison can be made."

using 3.14 for Pi , since you didn't say what value to use
area = PI x r^2
Area of larger circle = 3.14 x 500^2 = 785,000 square units
area of smaller circles = 3.14 x 1^2 = 3.14 square units
785,000/ 3.14 = 250,000 small circles can fit into larger one
The first choice does NOT represent a function
Step-by-step explanation:
the x vaules in the first two ordered pairs (2), each have a different y value which makes it nonfunctional :)
Answer:
x^3 - 2x^3 - 17x - 18
Step-by-step explanation:
Multiply each term in the first expression by each term by the second expression and combine like terms.
