Kaitlyn has a bag with an equal number of red, yellow, and blue marbles. She makes a tree diagram to show the sample space if she randomly selects two marbles out of the bag.

[diagram in the picture]

Answers

Answer:

6/9

Step-by-step explanation:

there are the possibility that she takes different colors six times in 9 different possible results

The probability that both marbles selected are different colors is 2/3.

What is the probability?

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.

Given that, Kaitlyn has a bag with an equal number of red, yellow, and blue marbles.

From tree diagram, we have {RY, RB, RR, YR, YB, YY, BR, BY, BB}

Here, the probability = 6/9

= 2/3

Therefore, the probability that both marbles selected are different colors is 2/3.

2. 8x + 10

3. 10x + 8

4. -9x + 15

5. -5x + 17

Step-by-step explanation:

In the first problem, you have to do -5x + -8x which is -13x. Then you add 2+9 which is 11. You will get the expression -13x + 11.

In the second problem, you have to do 5x + 3x which is 8x. Then you add 8 + 2 which is 10. You will get the expression 8x + 10.

In the third problem, you have to do 1x + 9x which is 10x. The. you add 4 + 4 which is 8. You will get the expression 10x + 8.

In the fourth problem, you have to do -7x + -2x which is -9x. The. you add 6 + 9 which is 15. You will get the expression -9x + 15.

Question
Calculate the volume of the prism by first finding the total number of half-unit
cubes that will fill it. There are 8 half-unit cubes in every unit cube.
O A. Number of half-unit cubes = 5
V=1 cubic units
O B. Number of half-unit cubes = 10
V=12 cubic units
OC. Number of half-unit cubes = 10
V = 5 cubic units
O D. Number of half-unit cubes = 5
V = 2) cubic units

Answers

Answer:

B

Step-by-step explanation:

the way they are explaining the problem doesnt quite make sence, but from what i can tell...

the volume of the cube is 1 1/4, i came up with this because i used the method of multiplying width by height by length

1/2 * 1 * 2 1/2 = 1 1/4

so if theres 8 half unit cubes per unit cube, then we can take the two numbers given to us and divide them by 1 1/4 or 1.25 in decimal

5 / 1 1/4 = 4

10 / 1 1/4 = 8

so your answer is B

The answer is b anyways have a good day
