Jung wanted to find out which band was most popular among the high school students. Where should he conduct his survey to get the most unbiased survey.

A=in the school cafeteria
B=at a school dance where band A is playing
C= at the record store where a member of band B is giving autographs
D=at the school next board meetings

I'd say A

Step-by-step explanation:

Reason: Because B and C are both having bands there and the cafeteria has the students popular opinion where there isn't band influence.

A in the school cafeteria

Step-by-step explanation:

B and C would be biased surveys and D is teachers not high school students so the answer is A

i believe the answer is d.

hope it you! : d

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
