Sue wants to know how many families in her small neighborhood of 50 homes would volunteer to at a neighborhood animal shelter. she put all the addresses in a bag and drew a random sample of 25 addresses. she then asked those families if they would volunteer to at the shelter. she found that 18% of the families would volunteer to at the shelter. she claims that 18% of the neighborhood families would be expected to at the animal shelter. is this a valid inference? yes, this is a valid inference because the 25 families speak for the whole neighborhood yes, this is a valid inference because she took a random sample of the neighborhood no, this is not a valid inference because she only asked 25 families no, this is not a valid inference because she did not take a random sample of the neighborhood

I belive the answer would be C.  

Step-by-step explanation:

Hope this helps! :D

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.

step-by-step explanation:

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!
