Ross wants to conduct a survey of his 400 classmates to determine which candidate for class treasurer, warren or willa, is in the lead in the upcoming election.
ross will ask the question, “if the election were today, which candidate would get your vote? ”
which of the following methods of surveying his classmates will allow ross to make valid conclusions about which candidate is in the lead?
select all that apply.
*ask all of warren's friends.
*ask the other members of willa's cheerleading squad.
*put the names of all the students in a hat, and draw 100 names. ask those students whose names are drawn.
*ask every student in the class.

Put the names of all the students in a hat, and draw 505050 names. Ask those students whose names are drawn.

Step-by-step explanation:

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
