Step-by-step explanation:
The chance to win = 1 : 6³ = 1 / 216
To win $500, the player needs to pay $216 on average.
500/ 216 = 2.31
$2.31 win and $1 cost per game gives $1.31 net win.
Hello from MrBillDoesMath!
Answer: radius = 20
Discussion:
The distance between two complex points z1 ( = x1 + i y1) and z2 ( = x2 + iy2) is
sqrt ( (x1-x2)^2 + (y1-y2)^2)
In our case z1 = -10 - 1i and z2 = 6 + 11i. Per the above formula, the distance, or radius of the circle, is given by
sqrt ( (-10 - 6)^2 + ( -1 - 11)^2 ) =
sqrt ( ( -16)^2 + (-12)^2) ) =
sqrt ( 256 + 144) =
sqrt(400) =
20
Thank you,

Answer:
An equation could be 2-4= -2
Step-by-step explanation:
You would count down 4 times from the the number 2 (below the line that says 3) then your answer would be -2 since below it, is -3. Obviously the number obove it would be 2.
Answer:
-d - 9 < 1.5
Step-by-step explanation:
In this problem, my reasoning is shown below for each individual inequality. We can test each one to see if it is true or not.

-23 is not greater than 1.5, so it can't be the first one. Let's try the next one.

Yes! -23 is smaller than 1.5. So we can say that the second option is correct. But just for good measure, we can try the other two.

Nope! -23 is not greater than 1.5. Let's try the last one.

And again... nope. 5 is not smaller than -1.5. So our reigning option is -d - 9 < 1.5. Hopefully this was helpful! If you have any more questions, let me know.
