yul has lunch at a restaurant. If his bill is 14.50 and yul wants to leave 20% tip, what is the amount he should leave for the tip

Answers

If you would like to know what is the amount of money Yul should leave for the tip, you can calculate this using the following steps:

20% of $14.50 = 20% * 14.50 = 20/100 * 14.50 = $2.9

Result: Yul should leave $2.9 for the tip.

final exam is an example of which experimental design principle?

A. Randomization
B. Blocking
C. Direct control
D. Replication

Answers

Answer:replication

Step-by-step explanation:

Final answer:

In the experiment, giving every student the same final exam is an example of direct control. This experimental design principle ensures that all other variables are kept constant so that any differences in the outcome can be attributed only to the variable being tested.

Explanation:

In this experiment studying the effect of the time of day a science class is taught on test scores, giving every student in the experiment the same final exam is an example of the experimental design principle known as direct control. The direct control principle ensures that all other variables except the one being tested (in this case, the time of day) are kept constant. This is done to make sure that any differences observed in the outcome (the test scores in this case) can be attributed only to the variable being tested. Therefore, all students taking the same exam ensures that the difficulty of the test doesn't affect the results.
