A container holds 9 red markers, 13 blue markers, and 17 green markers. You will randomly select two markers without replacement

IRISSAK [1]

Answer:

R-------8/38--------RR

R------9/39--------B-------13/38-------RB

G------17/38--------RG

R-------9/38--------BR

B--------13/39------B-------12/38-------BB

G-------17/38-------BG

R-----9/38--------GR

G---------17/39-------B------13/38-------GB

G------16/38-------GG

b).

9 ways
ways you can select 1 blue are; RB,BR,BG,GB

RB=9/39 × 13/38=3/38

BR= 13/39 × 9/38 =3/38

BG= 13/39 × 17/38=17/114

GB= 17/39 × 13/38=17/114

=3/38 +3/38+17/114+ 17/114 =26/57

Probability of selecting 2 red markers= RR = 9/39 × 8/38 =12/247

Probability of selecting a green marker and then a red marker= GR= 17/39×9/38 =51/494

5. HELP ASAP!!! GIVING BRAINLIEST!!! Find each missing measure.

Sladkaya [172]

Answer:

x = 6

Sorry if this answer is not correct, if it is or is not, please tell me in the comments!

Step-by-step explanation:

All of the angles add up to 180 degrees (since it is a triangle), so

(11x - 3) + (7x + 5) + (13x - 8) = 180

Then, combine the like terms.

31x - 6 = 180

Now, out goal is to separate the x from everything. To do that, we need to add 6 to 180.

31x = 186

Then divide by 31.

x = 6

(Feel free to replace x with 6 back in the previous equation to double check it!)

HELP! will give brainlest or whatever its called... Triangle ABC has vertices A(–2, 3), B(0, 3), and C(–1, –1). Find the coordin

Tomtit [17]

Answers:

A ' = (-2, -3)

B ' = (0, -3)

C ' = (-1, 1)

=======================================================

Explanation:

To apply an x axis reflection, we simply change the sign of the y coordinate from positive to negative, or vice versa. The x coordinate stays as is.

Algebraically, the reflection rule used can be written as $(x,y) \to (x,-y)$

Applying this rule to the three given points will mean....

Point A = (-2, 3) becomes A ' = (-2, -3)
Point B = (0, 3) becomes B ' = (0, -3)
Point C = (-1, -1) becomes C ' = (-1, 1)

The diagram is provided below.

Side note: Any points on the x axis will stay where they are. That isn't the case here, but its for any future problem where it may come up. This only applies to x axis reflections.
