Answer:
After factorizing the given expression we get the value as 
.
Step-by-step explanation:
Given:
We need to factorize the given expression using GCF.
Solution:
Now GCF means Greatest common factor.
From the given 2 numbers we need to find the greatest common factor.
In the given expression GCF is 'x'.
Hence we can say that;
Hence After factorizing the given expression we get the value as .
Answer: The volume would be 61.261.
Step-by-step explanation: To find the volume of a sector of a cylinder use the following formula and fill in the variables with the appropriate data. V = π r² h * Θ / 360°
Answer: 2
each counter is 1/8, so two is 2/8 which is equivalent to 1/4
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."
