Miranda 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?
a. twenty names from each grade pulled blindly from a container filled with the names of the entire student body written on slips of paper
b. every tenth person walking down main street in town at different times of the day
c. all of the students who write into the school newspaper
d. every student from all of miranda’s classes

A.twenty names from each grade pulled blindly from a container filled with the names of the entire student body written on slips of paper

Step-by-step explanation:

Choosing from the names of the entire student body gives us a representative sample.  Choosing them blindly from a container gives us a random sample.

Choosing people walking down Main Street does not guarantee we will get students at the school.

Choosing all of the students who write in to the paper would only give us people that are interested.

Choosing students that are in Miranda's classes only represents her grade level, not the entire school.

tickets for the harlem globetrotters

show at michigan state university in

2010 cost $16, $23, or, for vip seats, $40.

total revenue = 16x + 23y + 40z

if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, sales of all three kinds of tickets would

total $46,575.

16x + 23y + 40z = 46575, how many of each kind of ticket would

have been sold?

solve for x, y and z

x − 9z = 0

x − y − z = 55

16x + 23y + 40z = 46575

x = 1170

y = 985

z = 130
