iranda is conducting a poll to determine how many students would attend a students-only school dance if one was held. Which sample is most likely to yield a representative sample for the poll? twenty names from each grade pulled blindly from a container filled with the names of the entire student body written on slips of paper every tenth person walking down Main Street in town at different times of the day all of the students who write into the school newspaper every student from all of Miranda’s classes

20 names from each grade

Step-by-step explanation:

The two answers it comes down to are between every student from all of her classes and 20 students from each grade, however since the poll wants to determine how many people across the entire student body would attend, pulling from just Miranda's classes would add a grade level bias to the dance and would not be entirely random. 20 students from each grade is completely unbiased and properly represents the entire student body.

20 names each grade

Step-by-step explanation:

1. 8

2. 9

3. 20

4. 3

5. 17

6. 2.2

7. 11.25

8. 1

9. 14

10. 2

step-by-step explanation:

thats the first half

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
