Answer:

All in all, Jonathan's piggy bank contains 100 coins. Among these coins, only 50 are one-dollar coins. Therefore, the theoretical probability of picking one-dollar coin from the piggy bank is equal to 50/100 or 1/2.

Similarly, from the experiment, 20 coins were picked and among these there are 12 one-dollar coins. The answer to the second question is therefore 12/20 or 3/5.

Using sampling concepts, it is found that this is an example of independent samples.

For dependent samples, there is a paired measurement for one set of items.
For independent samples, separate measurements are made on two different sets, that is, the value on one sample reveal no information about the values on the other sample.

In this problem, there are two samples, the sample composed of male workers and the one composed of female workers, and separate measurements are taken, hence, it is an independent sample.

Answer: $\text{quadrilateral FSHB}\sim\text{quadrilateral KTWJ }$

Step-by-step explanation:

To polygons are said to be similar if all the corresponding angles of given polygons are equal.

In the given figure, it can be seen that in quadrilateral FSHB and quadrilateral KTWJ all the corresponding angles are equal.

∠F=∠K

∠S=∠T

∠H=∠W

∠B=∠J

Therefore, The given polygons are similar.

Hence, $\text{quadrilateral FSHB}\sim\text{quadrilateral KTWJ }$
