first answer is (A)
second answer is 15 ft tall
Step-by-step explanation:
if you divide 150 by 6 you get 50 so since their are 3 even and odd numbers you cut 50 in half and it'll be 25
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."

Answer:
y=-3
Step-by-step explanation:
Answer:
x = 34
Step-by-step explanation:
Add x+24 to both sides of the equation and simplify.
2 + 8 - x + x + 24 = -24 + x + 24
34 = x
