The manager of a school radio station is conducting a survey. She wants to find out which
type of music students prefer. How would the manager most likely get a random sample
that represents the school population?
a. ask five students from each grade in the school
b. ask each member of the school band and the chorus
c. ask every fifth student who attends the school from the student list
d. ask every fifth student who attended the last school concert

The answer is : Ask every student who attended the last school concert. ^.^ Hope I helped!!

Step-by-step explanation:

b. ask each member of the school band and the chorus

or

c. ask every fifth student who attends the school from the student list

Step-by-step explanation:

not sure if it is right

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
