Two number cubes are rolled. What is the probability of rolling a sum of 9 or a sum that is even?
Murljashka [212]

Well I don't know !
Let's figure it out together.

Each cube can land in 6 different ways, so the total number
of possible results with two cubes is (6 x 6) = 36 .

Now we need to figure out how many of those 36 possibilities
meet your specifications ... either 9 or any even number.

Ways to make 9 :

3 . . . 6
6 . . . 3
4 . . . 5
5 . . . 4

Four ways to make 9.
____________________________

Ways to make an even number:

1 . . . 1
3 . . . 1
1 . . . 3
2 . . . 2
5 . . . 1
1 . . . 5
6 . . . 2
2 . . . 6
6 . . . 4
4 . . . 6
6 . . . 6

Eleven ways to make an even number.
_____________________

Total number of ways to succeed = (4 + 11) = 15 ways

So the probability of succeeding (rolling 9 or an even number)
is

               15 / 36  =  5 / 12  =  0.41666... =  (41 and 2/3) % .

I'm solving for x, but I'm not confident with my work. I feel like x should be smaller than the other side (121) but I got a res
sergejj [24]

You have the ratios set up but you need to cross multiply everything:

(5x + 10) x 11 = 121 x 10

55x + 110 = 1210

Subtract 110 from both sides:

55x = 1100

Divide both sides by 55:

X = 1100 / 55

X = 20

The area of a rectangular picture frame is 4 1/3 square inches. The length of the frame is 3 1/2 inches. Find the width of the f
goldenfox [79]

Answer:

13/14

Step-by-step explanation:

Area of a rectangle = l * b

=> 4 1/3 = 3 1/2 + b

=> (4 1/3) / (3 1/2) = b

=> (13/4) / 7/2  = b

=> 13/4 * 2/7

=> 13/2 * 1/7

=> 13/14

Therefore the width = 13/14

If my answer helped, kindly mark me as the brainliest!!

Thank you!!

Does anyone know how to do this? I’m lost
Nataly [62]

Answer: B

Step-by-step explanation:

To find the inverse function, you switch x with y and y with x. Then, you solve for y.

y=(x-1)^{2} -4                                  [switch x with y, and y with x]                        

x=(y-1)^2-4                                  [add both sides by 4]

x+4=(y-1)^2                                  [square root both sides]

\sqrt{x+4} =y-1                                    [add both sides by 1]

\sqrt{x+4} +1=y

f^-^1(x)=1+\sqrt{x+4}

Now that we know the inverse function, we can actually tell that the answer is B. We know this because of the restriction that f(x) is x≤1. This makes it positive, and B the answer.
