The conditional probability that a Philadelphian who got the flu got a flu shot is of:
0.4375 = 43.75%.
What is Conditional Probability?Conditional probability is the probability of one event happening, considering the outcome of a previous event.
The formula is presented as follows:
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which each probability in the formula is described as follows:
P(B|A) is the probability of the event B happening, given that the event A happened.[tex]P(A \cap B)[/tex] is the probability of both the events A and B happening.P(A) is the probability of the event A happening.In the context of this problem, the events are described as follows:
Event A: Got the flu.Event B: Got the flu shot.The probability of people who got the flu is obtained as follows:
2% of 70%. (got the shot).6% of 30%. (did not get the shot).Hence:
P(A) = 0.02 x 0.7 + 0.06 x 0.3 = 0.032.
The probability of both getting the flu and the shot is:
P(A and B) = 0.02 x 0.7 = 0.014.
Hence the conditional probability that a Philadelphian who got the flu got a flu shot is calculated applying the conditional probability formula as follows:
P(B|A) = P(A and B)/P(A) = 0.014/0.032 = 0.4375 = 43.75%.

x² + (y – 3)² = 36 and x² + (y + 8)² = 36 are equations that represent circles having a diameter of 12 units and a center that lies on the y-axis
How to find the equations of circles?Given : x² + (y – 3)² = 36, x² + (y – 5)²= 6, (x – 4)² + y² = 36, (x + 6)² + y² = 144 and x² + (y + 8)² = 36
and x² + (y + 8)² = 36
The standard form of the equation of a circle is
(x-a)² + (y-b)² = r²
where (a, b) is the center and r is the radius
Let's compare the given equations with the standard equation:
x² + (y – 3)² = 36 can be written as:
(x-0)² + (y – 3)² = 6²
This has a center (0, 3), radius r = 6 and diameter = 12 units
x² + (y – 5)²= 6 can be written as:
(x-0)² + (y – 5)² = (√6)²
This has a center (0, 5), radius r = √6 and diameter = 2√6 units
(x – 4)² + y² = 36 can be written as:
(x-4)² + (y – 0)² = 6²
This has a center (4, 0), radius r = 6 and diameter = 12 units
(x + 6)² + y² = 144 can be written as:
(x+6)² + (y – 0)² = 12²
This has a center (6, 0), radius r = 12 and diameter = 24 units
x² + (y + 8)² = 36 can be written as:
(x+0)² + (y + 8)² = 6²
This has a center (0, -8), radius r = 6 and diameter = 12 units

let us rename , the coordinates as A(0,2) , B(6,0) , C(0,-2) , D(-6,0) .
the distance between two points (x₁,y₁) and (x₂,y₂) can be calculated using the formula
d = √(x₂ - x₁)² + (y₂ - y₁)²
distance between A(0,2) and B(6,0) is
AB = √(6 - 0)² + (0 - 2)²
AB = √(6² + (-2)²)
AB = √(36+4)
AB = √40

What is compound interest?
Compound interest, also known as interest on principal and interest, is the practice of adding interest to the principal amount of a loan or deposit.
As given Jamal wants to save $54,000 for a down payment on a home with 8.2% APR, compounding daily for 5 years.
The compound interest formula is,
[tex]A = P(1+\frac{r}{n})^n^t[/tex]
where,
A = final amount
P = initial principal balance
r = interest rate
n = number of times interest applied per time period
t = number of time periods elapsed
Here, A = $54000, r = 8.2% = 0.082, t = 5, n = 365
Plug the values in the above formula,
[tex]54000 = P(1+\frac{0.082}{365} )^(^3^6^5^)^(^5^)\\54000 = P(1.0002246575)^1^8^2^5\\54000= P(1.5067483068)\\P = \frac{54000}{1.5067483068} \\P = 35,838.766\\P = 35838.77[/tex]

Answer:
[tex]\displaystyle \boxed{ y=\frac{3}{4}x-\frac{1}{2} }[/tex]
Step-by-step explanation:
First, we will find the slope. This is done by finding the change in y over the change in x.
[tex]\displaystyle \frac{y_{2} -y_{1} }{x_{2} -x_{1} }= \frac{4--5}{6--6} =\frac{4+5}{6+6}=\frac{9}{12}=\frac{3}{4}[/tex]
Next, we will find the equation. We will create a point-slope equation and simplify into slope-intercept form.
y - 4 = [tex]\frac{3}{4}[/tex](x - 6)
y = [tex]\frac{3}{4}[/tex]x - [tex]\frac{9}{2}[/tex] + 4

if evan does a job in 11 hours and with the help of himari they can do it together in 6 hours, how long would it take himari to do it alone?
Using World problem : work and time,
Himari will take 13 hour and 12 minutes to complete the job alone.
We have given that
Time taken by Even to do a job = 11 hours
let "x hours" be the time taken by humari to do this job alone .
Even'rate to do a job = 1/11 per hour
Himari and Even work together and do the job in 6 hours .
rate at which both are working together and do the job = 1/6 per hour.
Himari' rate to do job = 1/x hours per day
Now , using the formula "together work "
Even'rate + Himari'rate = rate of together work
=> 1/11 + 1/x = 1/6
we solve the above equation and find out the value of x
multiple both sides with 66x we get,
=> 6x + 66 = 11x
=> 5x = 66
=> x = 66/5 = 13 hours and 12 minute
Hence, Himari will take 13 hour and 12 minutes to do job alone .

(6x² -5x -12) - (2x² -9x +8)
= 6x² -5x -12 -2x² +9x -8
= (6 -2)x² +(-5 +9)x +(-12 -8)
= 4x² +4x -20

Okay, sorry for answering a few minutes late!
Step-by-step explanation:
So, for data in a table to be a function, the input must only have one output.
Short and sweet answer, hope this helps!

The value of [tex]\sqrt{13}[/tex] is between 3 and 4 on the number line.
What is a number line?A horizontal line with evenly spaced numerical increments is referred to as a number line. How the number on the line can be answered depends on the numbers present. The use of the number is determined by the question that it corresponds to, such as when graphing a point.
[tex]\sqrt{13}[/tex] = 3.60
The value 3.6 is going to be between 3 and 4 because it is seen to be more than 3 while the value is also seen to be less than 4.
Hence the solution to the problem is the locations are 3 and 4.

Kiran is competing in a bike race. The function rule t(s)=40/s relates the time in hours of a bike race with the average speed, s, in miles per hour. Identify the constant of proportionality and explain what it means in this situation.
Answer:
Step-by-step explanation:
so, I was just commenting about word problems to another person and here is a great example of a word problem that is too complex. They are using the term "function rule" that is too broad. They have probably defined it in some text somewhere and the teacher has mentioned in super briefly, but it's what the question is all about. We need to understand what "function rule" really means. They have also used the varible "s" which is mostly reserved for Laplace / Fourier transformations. This is just a really badly written question. Don't feel bad if you don't get what it's asking. it's messy at best. t(s) is then name of our function, it's rule ( the function rule) is 40/s it's constant of proportionality is 40 , This rule would also mean that at the very very start of the race... at .001 into the race, you'll be going 40,000 MPH , which is obviously not correct. There probably needs to be some more rule descriptions saying that s is an integer, and it can't be negative. Also note that after 4 hours of racing , the speed would be 40/4 or 10 MPH, this function rule is probably not accurate after some time. the speed probably starts out fast, slows down till the close to the very end of the race... they jumps up dramatically to the finish. Watch the Tour de France writer of this question. :D The riders slow down as the race progress according to this function rule. But I don't think that's at all accurate for a real bike race. they slow down only to a point... after the start.... then hold at that speed ... till close to the end.. then speed up a lot... like 50 MPH :0
An air traffic controller is tracking two planes. To start, Plane A is at an altitude of 3500 feet and Plane B is at an altitude of 1970 feet. Plane A is gaining altitude
at 40.25 feet per second and Plane B is gaining altitude at 65.75 feet per second.
How many seconds will pass before the planes are at the same altitude
What will their height be when they’re at the same altitude
60 seconds long will it take for the planes to reach the same altitude.
Given that,
Two planes are being monitored by an air traffic controller. Plane A is initially at an altitude of 3500 feet, while Plane B is initially at a height of 1970 feet. The altitude of Plane A is increasing at a rate of 40.25 feet per second, while Plane B is doing so at a rate of 65.75 feet per second.
We have to find how long will it take for the planes to reach the same altitude.
Let us take x as the number of seconds in time.
We get,
3500+40.25x for Plan A.
1970+65.75x for Plan B.
Take,
3500+40.25x=1970+65.75x
3500-1970=65.75x-40.25x
1530=25.5x
x=1530/25.5
x=60
Therefore, 60 seconds long will it take for the planes to reach the same altitude.
