If a player rolls 2 dice and gets a sum of 2 or 12, he wins $30. If the person gets a 7, he wins $10. Otherwise he wins nothing.

If the cost to play the game is $3, what does a player expect to get out of this game every time he/she plays?

If they were to win $30 they would expect to get $27 in profit.

If they were to win $10 they would expect $7.

If they were to win $0 they would expect $-3 in profit, so technically if they win nothing they lose money.

Hope I could help! :D

An equilateral triangle with a side length of 6mm and a height of 5.2mm is divided vertically into halves. Find the area of one
Viefleur [7K]

There are two ways you could go about solving this.

You could divide the length of the base (6mm) by 2 and use that to find the area or you could find the area of the whole triangle using 6mm and divide that by 2.

I will use the first method I described:

base = 6/2

base = 3 mm

height = 5.2 mm

area = bh/2

area = (3 * 5.2)/2

area = 7.8 square mm

(don't forget your units)


Using the other method would look like this:

area = bh/2

b = 6

h = 5.2

area = (6 * 5.2)/2

area = 15.6 square mm

area/2 = 7.8 square mm


As you can see either method yields the same result.

Hope this helped.

Cheers and good luck,

Brian

The table shows the record low temperatures for several states. Graph the temperatures on a number line.
OlgaM077 [116]

Step-by-step explanation:

Please find the attachment.

We have been given a table that shows the record low temperatures for several states. We are asked to graph the temperatures on a number line.

First of all we will draw a number line going to infinity into both directions.  

To graph the given temperatures on number line let us arrange temperatures in less negative order.  

-34, -32, -30, -29, -27.  

Since we know that numbers with large negative values lie on the left at number line. Let us graph our large negative temperature on the left at our number line.      

We can see that -34 is the most negative temperature, therefore, it will be on the left most side of our number line.  

-27 is greatest of our given negative temperatures. -27 is less negative temperature than our other given low temperatures, therefore, it will lie on the right most side of our number line.  

Other temperatures will lie between these two values according to their temperatures.    

-32 is second large negative temperature after -34, therefore, it will lie on the right side of -34.

-30 will lie on the right side of -32 and -29 will lie on the right of -32.
