Answer:
The statement is true.
Step-by-step explanation:
Given : Reflecting the graph of y = sin x across the y-axis is the same as reflecting it across the x-axis.
To find : Is this statement true or false?
Solution:
Rules of reflection :
Along across y-axis if we have a point
So, y=sinx
The reflection across y-axis→ .......[1]
Along across x-axis if we have a point
so, y=sinx
The reflection across x-axis → .....[2]
Hence, [1] and [2] both of them are equal
Therefore, the statement is true.

Step-by-step explanation:
The nature of the research is called Observational Study while the target Population is American Students.
<h3>How to find the sampling method?</h3>
1) In study, we survey members of a sample without trying to affect them while in experiment, we assign people or things to groups and apply some treatment to one of the groups, while the other group does not receive treatment. Thus, this is an observational study.
2) The sample is the 100 students made up of 50 boys and 50 girls.
3) The target Population are American College Students
4) The sampling method is; Simple random Sampling
5) The data is qualitative because it deals with description of feelings rather than dealing with numbers and figures.
6) It is unlikely that the results would be invalid because of sampling bias as it was only done in a private university.

Answer:
d = 101
Step-by-step explanation:
t = 11
11 x 11 = 121
-20 + 121 = 101
check: 101- 121 = -20 (correct)
The answer to your question 29 is E 935,00. The way how I got this answer by multiplying 55 and 17,000 and by that the is E. For question 30 the answer is H. The way how I got this answer is by knowing twice means 2 times so by that H was the only one with 15+2n so by that I knew that was the answer.
Hope this helps:)
