Answer:

10 one-dollar  and 4 five-dollar bills.

Step-by-step explanation:

Let x = the number of one-dollar bills and y = number of five-dollar bills.

Then:

x + y = 14

x + 5y = 30      (using the values of the bills)

Subtracting the 2 equations:-

-4y = -16

y = 4

so x + 4 = 14

x = 10.

There are 10  one-dollar bills and 4  five-dollar bills.

The size of the overall population is __________ in determining the reliability of a poll.
lidiya [134]

The size of the overall population is <u>not important</u> in determining the reliability of a poll.

<h3>What is the purpose of the overall population in a poll?</h3>

The overall population that a poll is based on does not have anything significant to do with the poll itself which means that it is not important in determining reliability.

This is because the poll uses a sample of the population and not the population itself.
