Answer:

12.0 units

Step-by-step explanation:

The top point is 9 units up and 8 units to the right of the bottom point.

Distance formula: a^2+b^2=c^2

8^2+9^2=c^2

64+81=c

c^2=145

c=12.04 ==> c=12.0 units

A political campaign wants to estimate the number of adult residents who voted in the last city election. Answer the following.
Svetradugi [14.3K]

Using sampling concepts, it is found that:

a) The best method is: 25 adult residents are randomly selected from the city;

b) The estimate is that 11,536 adults voted in the election.

<h3>What is sampling?</h3>

It is a common statistics practice, when we want to study something from a population, we find a sample of this population, which is a group containing elements of a population. A sample has to be representative of the population, that is, it has to involve all segments of the population.

In this problem, the sample will be representative if all adults, no matter if senior or not, homeowners or not are represented, hence the best method is:

25 adult residents are randomly selected from the city;

The estimate of the number of adults that voted is:

14/25 x 20,600 = 11,536.
