Please don't guess the answer, and give an explanation, thank you! Linda wants to conduct a survey to find out how much time students from her school spend reading books in a local library. Which of the following is an appropriate statistical question for this survey?

How many hours per week do you read books in the library?
How many times does the fastest reader go to the library in a week?
How many of you read books in the library for an hour every day?
How many of you read books in the library for more than an hour every day?

I think the answer to this question is that Linda should ask the first question.

Step-by-step explanation:

This is because if she asks the first question, she will know how many students go to the library and how many hours per week do they spend reading books in the library

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
