When playing the roulette at a casino, you have exactly 1/35 chance of winning in each round if you play a single number. Your friend has rigged up some fireworks to be set off when you win. When you win, he sets off the fireworks every time. When you don't win, he accidentally sets off the fireworks 10% of the time. If you failed to see the outcome of a round, but you see the fireworks going off, then what is the probability that you actually won that round?
Answer:
0.2275 = 22.75% probability that you actually won that round
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Fireworks going off
Event B: You won
Probability of fireworks going off.
100% of 1/35 = 0.0286(when you win)
10% of 34/35 = 0.9714(you lost). So
[tex]P(A) = 0.0286 + 0.1*0.9714 = 0.12574[/tex]
Probability of you winning and fireworks going off:
100% of 1/35, so [tex]P(A \cap B) = 0.0286[/tex]
If you failed to see the outcome of a round, but you see the fireworks going off, then what is the probability that you actually won that round?
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.0286}{0.12574} = 0.2275[/tex]
0.2275 = 22.75% probability that you actually won that round

Answer:
Step-by-step explanation:
Now e have two figures
1 is ABCD and other is APQD ,
Now to find g and f,
Now the are both figure is ,
Area = length * width
Area ABCD = 39 cm^2
AB* BC = 39
(g+7) * ( f) = 39Again,
Area APQD = AP*QD= 16 cm ^2
(g)*(f)=16from here f =16/g putt it in above equation we get ,
(g+7)*16/g = 39
16*g-39*g+96 =0
-23g +96 = 0
g = 96/23
g =3 cm
Now for f putt in one of the above equation ,
f =16/3
f =5.33 cm
Answer:
f = 3cm g = 6cm
Step-by-step explanation: to find f
Subtract the area of APQD from ABCD then divide by 7
f = (39 - 18)/7
f = 21/7
f = 3
To find g, divide the area of APQD by 3
18/3 = 6
We can do this because of the givens: ABCD is a rectangle, PQ is parallel to AD, so BC=AD=PQ
What is the image of (-9,0) after a reflection over the x-axis?
Answer:
(-9, 0)
Step-by-step explanation:
When a point is reflected over the x-axis, the x-coordinate stays the same but the y-coordinate turns into its opposite. So, the x-coordinate would stay as -9. Because zero is neither negative nor positive, it doesn't have an opposite. So, the y-coordinate would still be 0.

Answer:
x = 20
Step-by-step explanation:
The picture shows that there is a right angle (this is indicated by the square in between the two straight lines)
every right angle has a total measure of 90 degrees
knowing this we can say: x + 70 = 90 or x = 90 - 70
either way, you would solve this to get x = 20

Nathan built a triangular garden in his backyard, as shown.
How much of the backyard is not covered by the garden?
A.141 square feet
B.78 square feet
C.120 square feet
D.99 square feet
Answer:
Step-by-step explanation:
Subtract the area of the triangle from the rectangular area. AT=bh/2 and AR=LW so
A=12(10)-7(6)/2
A=120-21
A=99 ft^2
Select all the options that represent different forms of the number 500,368? A. Five hundred, three thousand, and sixty-eight B. Five hundred thousand, three hundred sixty-eight. C. 5,000 + 300 + 60 + 8 D. 5 hundred thousands + 3 hundreds + 6 tens + 8 ones E. 500,000 + 300 + 60 + 8
Answer:
B, D, and E
Step-by-step explanation:
B. Five hundred thousand = 500,000/ three hundred = 300/ sixty-eight = 68.
D. 5 hundred thousands = 500,000/ 3 hundreds = 300/ 6 tens = 60/ 8 ones = 8.
E. 500,000 + 300 + 60 + 8 = 500,368.

Noah is painting boxes that are all the same size. He used 2 ounces of paint to cover 1 2/3 boxes. How many ounces of paint are needed to cover 1 box? Draw a diagram to represent the situation, then find the answer.
Answer:
2:1 2/3
?oz:1/3. How many oz does it take to cover 1/3 of the box?
0.4:1/3. 0.4oz is needed to cover 1/3 of the box.
1/3*3=1. 0.4*3=1.2 *= multiplication
I believe the answer Is: 1.2oz is needed to cover 1 box. The information here should help you the diagram.
Noah needs 1.2 ounces of paint to cover 1 box.
Given that Noah is painting boxes that are all the same size, and I have used 2 ounces of paint to cover 1 2/3 boxes, to determine how many ounces of paint are needed to cover 1 box, the following calculation must be performed:
1.666 = 2 1 = X 2 / 1,666 = X 1.2 = X
Therefore, Noah needs 1.2 ounces of paint to cover 1 box.

A research group is interested in gauging perceptions about airline food quality among first class passengers. Specifically, they wish to determine the percentage of business travelers In the United States that believe airline food quality has not improved. They listed the members of the airline's frequent flyer club in alphabetical order and took every tenth member until they succeeded in contacting 170 members. What kind of sampling method have theyused?
a. MULTISTAGE SAMPLING
b. CLUSTER SAMPLING
c. STRATIFIED RANDOM SAMPLING
d. SYSTEMATIC SAMPLING
Answer:
d. SYSTEMATIC SAMPLING
Step-by-step explanation:
Samples may be classified as:
Convenient: Sample drawn from a conveniently available pool.
Random: Basically, put all the options into a hat and drawn some of them.
Systematic: Every kth element is taken. For example, you want to survey something on the street, you interview every 5th person, for example.
Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.
Stratified: Also divides the population into groups. However, then only some elements of the group are surveyed.
In this question:
Took every 10th member, that is, every kth member, which is systematic.
The correct answer is given by option d.

You earn $42 for washing 7 cars. How much do you earn for washing one car? How much do you earn for washing 3 cars? How much do you earn for washing 5 cars?
Answer:
1 car = $6 ; 3 car = $18 ; 5car = $30
Step-by-step explanation:
$ 42 = 7 cars
so 1 car = $42÷7 = $6
so 3 cars = 3 × $6 = $18
so 5 cars = 5 × $6 = $30
