hello,
Jack wants to know how many families in his small neighborhood of 60 homes would help organize a neighborhood fund-raising party. He put all the addresses in a bag and drew a random sample of 30 addresses. He then asked those families if they would help organize the fund-raising party. He found that 12% of the families would help organize the party. He claims that 12% of the neighborhood families would be expected to help organize the party. Is this a valid inference?
Yes, this is a valid inference because the 30 families speak for the whole neighborhood
it's the correct one because if he ask 30 families so they talk to their neighborhood so its will be 60 ;) so its correct,
hope this help
I believe the answer would be 11.99, because 20% times 59.95 is 11.99

Step-by-step explanation:
The circumference of a circle can be found using the following formula:

where d is the diameter. We are given the radius, so let's find the diameter.
The diameter is twice the radius.

The radius is 15 feet.

Multiply.

Now we know the diameter. Substitute 30 feet in for d.


We are using 3.14 for pi, so substitute it in.

Multiply.

The circumference of the circle is 94.2 feet.
