The probability of selecting the red marble and yellow marble is 18/169.
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, a bag contains 3 red, 4 blue, and 6 yellow marbles.
Total number of outcomes = 3+4+6=13
Probability of selecting red marble = 3/13
Probability of selecting yellow marble = 6/13
So, P(red and yellow) = 3/13 × 6/13
= 18/169
Therefore, the probability of selecting the red marble and yellow marble is 18/169.

Help solve for X, please hurry I have 42 minutes
Answer:
A) 9
Step-by-step explanation:
First you need to find the measure of angle c
Since it's a quadrilateral, the interior angles add up to 360 degrees
Now there's two right angles and one 99 degree angle
Add those and subtract from 360
360 - (90+90+99) = 81
C = 81 degrees
However x is the root of c so root 81 is 9

Dr. Barber needs to pay her employees $15.00 an hour. If she has five
technicians and they each worked 25 hours, how much money in total will Dr.
Barber pay all of the technicians?
Answer:
$1,875
Step-by-step explanation:
$15.00 per hour (multiply by hours)
per technician (multiply by technicians)
so: 15x25=375 then 375x5=1,875
Answer:
$1875
Step-by-step explanation:
First, let's find how many hours the technicians worked
She has 5 technicians, and the each worked 25 hours
We can multiply 5 and 25 to find the total number of hours
5*25=125
Now we know that the technicians worked 125 hours altogether. Now, we need to find how much money that is.
They worked 125 hours, and they are paid $15 per hour
We can multiply 125 and 15 to find the cost
125*15=1875
So, Dr. Barber will pay the technicians $1875 in total

Abe can paint the room in 15 hours, Bea can paint 50 percent faster than Abe, and Coe can paint twice as fast as Abe. Abe begins to paint the room and works alone for the first hour and a half. Then Bea joins Abe, and they work together until half the room is painted. Then Coe joins Abe and Bea, and they work together until the entire room is painted. Find the number of minutes after Abe begins for the three of them to finish painting the room.
90 + 12/5 x 60=90 + 144 +100= 334
so 334 would be your answer
The number of minutes after Abe begins for the three of them to finish painting the room is; 344 minutes
We are told that Abe can paint the room in 15 hours.
Converting to minutes gives; 15 × 60 = 900 minutes
If the area of the room to be painted is x.
Then area painted per minute is; x/900
Now Bea paints 50% faster than Abe. Thus, rate bee can paint per minute is; 1.5x/900
Now,coe can paint twice as fast as Abe. Thus, rate coe can paint per minute is; 2x/900
Abbey works alone for the first hour and half. Thus, this is 90 minutes. Area covered by him in 90 minutes = (x/900) × 90 = x/10
Now, Bea joins Abe, and they work together until half the room is painted. Thus;x/10 + (x/900)t + (1.5x/900)t = x/2
Multiply through by 900 to get;
90x + xt + 1.5xt = 450x
Divide through by x to get;
90 + t + 1.5t = 450
2.5t = 360
t = 360/2.5
t1 = 144 minutes
Now, Coe joins Abe and Bea, and they work together until the entire room is painted. Thus;(x/900)t + (1.5x/900)t + (2x/900)t = x/2
Multiply through by 900/x to get;
t + 1.5t + 2t = 450
4.5t = 450
t = 450/4.5
t2 = 100 minutes
Thus, total time = 144 + 100
Total time = 244 minutes

3( 4x - 3) + 8 = 2x + 10x -1
Answer:
see below
Step-by-step explanation:
3( 4x - 3) + 8 = 2x + 10x -1
Distribute
12x - 9 +8 = 2x+10x -1
Combine like terms
12x - 1 = 12x - 1
Subtract 12x from each side
12x - 1 -12x = 12x - 1-12x
-1 = -1
This is true for all values of x
x = all real numbers
Answer:
All real numbers are solutions.
Step-by-step explanation:
3 ( 4x - 3 ) +8 = 2x + 10x - 1 Example 1:
12x - 9 + 8 = 12x - 1 3 ((4*1) -3) + 8 = (2*1) + (10*1) - 1
- 12x = -12x 3 ((4) - 3) + 8 = (2) + (10) - 1
-9 + 8 = -1 ( 12 - 9 ) + 8 = 12 - 1
-1 = -1 3 + 8 = 12 - 1
Example 2 11 = 11
3 ((4*6) - 3) + 8 = (2*6) + (10*6) - 1
3 ((24) - 3) + 8 = (12) + (60) - 1
72 - 9 + 8 = 72 - 1
72 - 1 = 72 - 1
71 = 71

4,7,9 is not a right angle triangle. If it was a right angle triangle then it show work in the formula a^2+b^2=c^2. But 4^2+7^2 doesn't equal 9^2. The hypotenuse or c should be 8.02 to be a right angle triangle.
The value of x decreased by 80% is y and the
value of x increased by 200% is z. What is the
value of z-y?
Answer:
The value of z-y is 14x/5
Step-by-step explanation:
The value of x decreased by 80% is → x - x * 80/100 = x - x*4/5 = x/5. This also equals to y → y = x/5. (1)
The value of x increased by 200% is → x + x * 200/100 = x + 2x = 3x. This also equals to z → z = 3x. (2)
If you substitute the values from the equation 1 and equation 2, the value of z - y → (3x) - (x/5) = 14x/5

<A and <B are supplementary angles. If m<A= (8x-25)° and m <B=(7x-5)° , then find the measure of <B. answer asap?
Answer:
Step-by-step explanation:
∠A + ∠B = 180 {supplementary angles}
8x - 25 + 7x - 5 = 180 {bring the like terms together}
8x + 7x - 25 - 5 = 180 {add the like terms}
15x - 30 = 180 {add 30 to both the side}
15x = 180 +30
15x = 210 {divide both sides by 15}
15x/15 = 210/15
x = 14
∠B = 7x - 5 = 7*14 - 5
= 98 - 5
∠B = 93°

You have a standard deck of cards. The deck has 52 total cards and contains 4 suits: hearts, clubs, diamonds, and spades. Each suit consists of cards numbered 2-10, a jack, a queen, a king, and an ace.
You select one card at random from the deck. Let A be the event that the randomly selected card is a diamond and let B be the event that the card is a king. Based on this information, answer the following questions.
Answer:
[tex]P(A) = \dfrac{1}{4}\\P(B) = \dfrac{1}{13}\\P(A \cap B) = \dfrac{1}{52}\\P(A/B) = \dfrac{1}{4}\\P(A/B) = P(A)\\[/tex]
A and B are not independent events.
Step-by-step explanation:
Total number of possibilities is 52 (Total number of cards in the deck).
Formula for probability of an event E can be observed as:
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]
For event A, number of cases possible for a card to be diamond = 13
[tex]P(A) = \dfrac{13}{52} \\\Rightarrow P(A) = \dfrac{1}{4}[/tex]
For event B, number of cases possible for a card to be a king = 4
[tex]P(B) = \dfrac{4}{52} \\\Rightarrow P(B) = \dfrac{1}{13}[/tex]
For the event, [tex]A \cap B[/tex], the card is a king and diamond, only one case is possible.
Because there is only one card for king of diamond.
[tex]P(A \cap B) = \dfrac{1}{52}[/tex]
Formula for P(A/B):
[tex]P(A/B) = \dfrac{P(A \cap B)}{P(B)}[/tex]
[tex]\Rightarrow \dfrac{\dfrac{1}{52}}{\dfrac{1}{13}}\\\Rightarrow \dfrac{1}{4}[/tex]
Yes, P(A) is same as P(A/B).
Here, A and B are not independent events because they have a common case i.e. a king is there which is of diamond in the deck.
Answer:
1/4
1/13
1/52
Yes, events a and b are independent events
