Which of the following represents the sample space for flipping two coins?

Afina-wow [57]

Step-by-step explanation:

Sample Space of any event E is the set of all possible outcomes whenever that event takes place.

Here, event E : Tossing 2 coins

Now, as we know, when an unbiased coin is tossed,

The total outcomes = {Head, Tail}

So, when two coins are flipped, the total outcomes are 2 x 2 = 4.

Sample space = { Head Head, Head Tail, Tail Head, Tail Tail}

or, S = { HH, HT , TH, TT}

A jazz concert brought in $134,000 on the sale of 8,500 tickets. If the tickets sold for $10 and $20 each, how many of each type

WINSTONCH [101]

Answer:

3600 $10 tickets

4900 $20 tickets

Step-by-step explanation:

We can use variables to represent the different types of tickets. Let "x" represent the amount of $10 tickets and "y" represent the amount of $20 tickets. Now we can set up a system of equations.

<h3>Setting up a System of Equations</h3>

We know that in total, 8500 tickets were sold. Therefore...

$x+y=8500$

Or in other words, "the amount of $10 tickets plus the amount of $20 tickets is equivalent to 8500 tickets in total".

We also know that $134,000 was made. Therefore...

$10x+20y=134000$

Or in other words, "10 times the amount of $10 tickets plus the 20 times the amount of $20 tickets is equivalent to 134000". Notice that since each ticket costs $10/$20, we have to multiply each variable by that value. We can now solve this system of equations.

<h3>Solving the System of Equations</h3>

$x+y=8500\\10x+20x=134000$

We can solve this system of equations using the elimination method. First, make either the x or y value equivalent in both equations. To do this, we can multiply a whole equation by a certain value.

Multiply the first equation by 10:

$10x+10y=85000\\10x+20y=134000$
