Using the 36 possibilities found in the product table for rolling two dice, list and count
Umnica [9.8K]

Answer:

Outcome = (5,6) and (6,5)

Count = 2

Step-by-step explanation:

For simplicity, I've added the product table as an attachment and I'll use the attachment as a point of reference.

The sample space of the first die is:.

S1 = {1,2,3,4,5,6}

For the second

S2 = {1,2,3,4,5,6}

Looking at the attachment, the outcomes that are multiples of 11 are

(5,6) and (6,5) because when 5 and 6 or 6 and 5 are added together, we get a 11 which is a multiple of 11.

So, we have;

Outcome = (5,6) and (6,5)

And the count is 2

So, we have:

Count = 2

Can you solve 2x^2 = 200 in the method Completing the Square
Elanso [62]
Hello there ^ _ ^

2x² = 200
We need to start by dividing both sides by 2
2x²/2 = 200/2
x² = 100
Now we can take square root.
x = +/-√100
x = 10 or x = -10

I hope this help!
