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

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
