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?
Answers
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

To find:
The set A'
Solution:
We know that,
Complement of a set A = Universal set - set A
A' = U - A
= {c, d, e, f, g, h, i} - {c, e, h, i}
= {d, f, g}
Therefore, the set A' is A' = {d, f, g}.

What is the image of (-9,0) after a reflection over the x-axis?
Answers
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.

Write an equation of a line that passes through the two given points. Your answer should be written in slope-intercept form.
P(-8,-8),q ( 0,0)
Answers
Answer:
y = x
Step-by-step explanation:
Find the slope using rise over run (y2 - y1) / (x2 - x1)
Plug in the points:
(y2 - y1) / (x2 - x1)
(-8 - 0) / (-8 - 0)
-8 / -8
= 1
So, the slope is 1.
Plug in the slope and a point into y = mx + b and solve for b:
y = mx + b
-8 = 1(-8) + b
-8 = -8 + b
0 = b
Plug in the slope and y intercept into y = mx + b
y = mx + b
y = 1x + 0
y = x
So, the equation of the line is y = x

investment A save £160 per month for 2 years. 2.5% interest is added to the total amount saved. Investment B invest £3800. Compound interest is added at 3% each year
Answers
Answer:
95.42
Step-by-step explanation:
Investment A:
160*24*1.025=3936
Investment B:
3800(1+.03)^2=4031.42
4031.42-3936= 95.42
Investment B is 95.42 more than investment A.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given,
investment A save £160 per month for 2 years.
2.5% interest is added to the total amount saved.
Investment A:
160×24×1.025=3936
Investment B:
Investment B invest 3800.
Compound interest is added at 3% each year
Convert 3% to decimal value by dividing 3 by 100.
3/100=0.03
P=A(1+r)t
A is initial deposit, r is rate of interest and t is time
3800(1+0.03)²
3800(1.03)²=3800×1.0609
=4031.42
We need to find how much investment B has more than investment A.
To find this let us find difference between investment A and investment B.
4031.42-3936= 95.42
Hence investment B is 95.42 more than investment A.

20%
Step-by-step explanation:
When asked, "x is what percent of y?" divide x by y and multiply by 100.
9/45 = 0.2
0.2 * 100 = 20%
Recall that we multiply by 100 to convert decimal to percent.
Step-by-step explanation:
Let x% of 45 be 9 Then
x % of 45 = 9
x / 100 * 45 = 9
45x = 900
x = 900 / 45
x = 20%

The 4 interior angles in the square are each 90 degrees. The four angles formed by the intersection of the 2 diagonal lines are each 90 degrees. The rest of the angles <PQT, <RQT, etc. Are all 45 degrees.
Answer:
The following angles are 45 degrees: SPT, QPT, PQT, RQT, QRT, SRT, RST, PST.
The following angles are 90 degrees: STP, PTQ, QTR, RTS
Step-by-step explanation:
Notice that it is a square. Since it is a square, any diagonal line drawn from a corner to the opposite corner will bisect the angle at both corners. Since in a square each angle at each corner is 90 degrees, we know that the angles listed above are 45 degrees.
There are multiple ways to arrive at the conclusion that angles STP, PTQ, QTR, RTS are all 90 degrees. The easiest way to arrive at that answer is looking at each triangle. Notice how the square is divided into 4 triangles. Each triangle contains two 45 degree angles. Since the internal angles of each triangle must sum to 180 degrees, this means the last angle is 90 degrees.
