Answer:
The probability of success if you switch to one of the remaining 4 doors is
[tex]P(K) =\frac{4}{9}[/tex]
Step-by-step explanation:
From the question we are told that
The number of doors is n = 9
Generally the probability that the car is in the door you choose is
[tex]P(C) = \frac{1}{9}[/tex]
Generally the probability that the car is in the rest of the doors is
[tex]P(C)' = \frac{8}{9}[/tex]
Given that Monty Hall opened the 4 goat doors then the probability that the car will be in the remaining 4 doors is mathematically evaluated as
[tex]P(K) = \frac{P(C)'}{2}[/tex]
=> [tex]P(K) = \frac{\frac{8}{9}}{2}[/tex]
=> [tex]P(K) =\frac{4}{9}[/tex]
Thus the probability of success if you switch to one of the remaining 4 doors is
[tex]P(K) =\frac{4}{9}[/tex]

Step-by-step explanation:
A test is used to determine if people have a predisposition for the formation of a blood clot inside a blood vessel that obstructs the flow of blood through the circulatory system. It is believed that 3% of people actually have this predisposition. The test is 99% accurate if a person actually has the predisposition, meaning that the probability of a positive test result when a person actually has the predisposition is 0.99. The test is 98% accurate if a person does not have the predisposition. What is the probability that a randomly selected person who tests positive for the predisposition by the test actually has the predisposition
Answer:
The probability that a randomly selected person who tests positive for the predisposition by the test actually has the predisposition is 0.6049.
Step-by-step explanation:
We are given that it is believed that 3% of people actually have this predisposition. The test is 99% accurate if a person actually has a predisposition.
The test is 98% accurate if a person does not have a predisposition.
Let the probability that people actually have predisposition = P(PD) = 0.03
The probability that people do not have a predisposition = P(PD') = 1 - P(PD) = 1 - 0.03 = 0.97
Let A = event that the test is accurate
So, the probability that the test is accurate if a person actually has a predisposition = P(A/PD) = 0.99
The probability that the test is correct if a person actually has a predisposition = P(A/PD') = 1 - 0.98 = 0.02
Now, the probability that a randomly selected person who tests positive for the predisposition by the test actually has the predisposition = P(PD/A)
We will use Bayes' theorem to calculate the above probability.
P(PD/A) = [tex]\frac{P(PD) \times P(A/PD)}{P(PD) \times P(A/PD) + P(PD') \times P(A/PD')}[/tex]
= [tex]\frac{0.03 \times 0.99}{0.03 \times 0.99+0.97 \times 0.02}[/tex]
= [tex]\frac{0.0297}{0.0491}[/tex] = 0.6049.
PLEASE HELP ME!! What is 3,200 as a product of its factors?? This for 6th grade
Answer:
3,200 is first divided by 2 which is smallest prime number . Then the answer is get 1,600 . Again this number is divided by 2 then answer is 800 . This step is continues for all time . So , it is again divided by 2 then answer comes 400 then divided answer comes 200. Then again divided by 2 then answer is 100 and again divided by 2 then answer is 50 again divided by 2 then answer is 25. now we cannot divided by 2 this number 50. Then what to do? we have to use prime number .so we have to divided by 5 then answer is 5. In last ,for checking we have to multiply all this prime number to check this answer.

Use the binomial probability
distribution below to find the
probability that the number of successes is at most five.
x P(x)
00.000
10.004
2 0.033
3 3 0.132
40.297
50.356
6 0.178
===================================================
Method 1
Add up the P(x) values from x = 0 to x = 5
0.000+0.004+0.033+0.132+0.297+0.356 = 0.822
-----------------------------------------
Method 2
If A and B are complementary events, then P(A)+P(B) = 1 and that leads to P(B) = 1-P(A).
We can think of the events defined as follows
A = event of getting at most 5 (ie 5 or less)B = event of getting 6Either A or B must happen, but not both simultaneously
P(B) = 0.178 from the table
P(A) = 1-P(B)
P(A) = 1-0.178
P(A) = 0.822
which is a shortcut compared to method 1. It's a much faster shortcut the larger the table is.
Classify the system of equations.
-3x = 3 - y
-1+y= 3x – 2
A. Intersecting
B. Parallel
C. Coincident
============================================================
Explanation:
Solve each equation for y. In other words, get y by itself
Let's start with the first equation
-3x = 3 - y
-3x - 3 = -y
-y = -3x-3
y = 3x+3
Do the same for the second equation
-1+y = 3x-2
y = 3x-2+1
y = 3x-1
The two equations we got were
y = 3x+3
y = 3x-1
Both have the same slope (m = 3) but different y intercepts, so we have parallel lines here.

An alarming number of U.S. adults are either overweight or obese. The distinction between overweight and obese is made on the basis of body mass index (BMI), expressed as weight/height 2. An adult is considered overweight if the BMI is 25 or more but less than 30. An obese adult will have a BMI of 30 or greater. According to a January 2012 article in the Journal of the American Medical Association, 33.1% of the adult population in the United States is overweight and 35.7% is obese.
A. What is the probability that a randomly selected adult is either overweight or obese?
B. What is the probability that a randomly selected adult is neither overweight or obese?
C. Are the events "overweight and "obese" exhaustive?
Answer:
(A) The probability that a randomly selected adult is either overweight or obese is 0.688.
(B) The probability that a randomly selected adult is neither overweight nor obese is 0.312.
(C) Yes, the events "overweight" and "obese" are exhaustive.
Step-by-step explanation:
We are given that an adult is considered overweight if the BMI is 25 or more but less than 30. An obese adult will have a BMI of 30 or greater.
According to a January 2012 article in the Journal of the American Medical Association, 33.1% of the adult population in the United States is overweight and 35.7% is obese.
Let the event , A = a person is overweight
B = a person is obese.
So according to the question;
The probability that an adult population in the United States is overweight = P(A) = 0.331
The probability that an adult population in the United States is obese = P(B) = 0.357
(A) As we know that the events of a person being overweight or obese cannot occur together.
This means P(A ∩ B) = 0.
Now, the probability that a randomly selected adult is either overweight or obese is given by = P(A [tex]\bigcup[/tex] B)
P(A [tex]\bigcup[/tex] B) = P(A) + P(B) - P(A ∩ B)
= 0.331 + 0.357 - 0
= 0.688
Hence, the probability that a randomly selected adult is either overweight or obese is 0.688.
(B) Now, the probability that a randomly selected adult is neither overweight nor obese is given by = P(A' [tex]\bigcup[/tex] B')
P(A' [tex]\bigcup[/tex] B') = 1 - P(A [tex]\bigcup[/tex] B)
= 1 - 0.688 = 0.312
Hence, the probability that a randomly selected adult is neither overweight nor obese is 0.312.
(C) Exhaustive events are those events which cannot occur together, but they form a sample space when combined together.
In our question also, the person can't be both overweight and obese at the same time, and together the event of a person being overweight or obese forms a sample space of people who are heavier.
Hence, the events "overweight" and "obese" are exhaustive.
A- 0.688.
B- 0.312.

What's something that could go wrong if you use numbers that are not precise?
Answer:
There are a lot of things that can go wrong, especially when we have an error in a measure that we use a lot of times (each time, that error increases).
For example, you think that each meter of fence costs $5, but the actual price is $5.30, and you need 40 meters, then you think that you may need to pay:
40*$5 = $200
But they will actually charge you:
40*$5.30 = $212.
Now this is a small example, now let's go to medicine, suppose that you want to trait cancer with radiation in a pacient, if you do not use precise measures for the dosage of radiation or the measures of the tumor, you may cause a lot of damage in the patient. (And similar cases if you want to give some medication and the numbers that you use are not precise, you may overdose the patient)
So the use of precise numbers may be critical in a lot of scenarios.

Explanation:
We cannot divide by zero.
To figure out when the expression is undefined, set the denominator equal to zero and solve for z.
The quadratic formula is the best route in my opinion.
[tex]6z^2+14z-80 = 0\\\\z = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\z = \frac{-14\pm\sqrt{14^2-4(6)(-80)}}{2(6)}\\\\z = \frac{-14\pm\sqrt{2116}}{12}\\\\z = \frac{-14\pm46}{12}\\\\z = \frac{-14+46}{12} \ \text{ or } \ z = \frac{-14-46}{12}\\\\z = \frac{32}{12} \ \text{ or } \ z = \frac{-60}{12}\\\\z = \frac{8}{3} \ \text{ or } \ z = -5\\\\[/tex]
Plugging in either z = 8/3 or z = -5 leads to the the denominator 6z^2+14z-80 to be zero. So either of these z values makes the given rational expression to be undefined.

In Oak Hill, Florida, 90% of all sunny days are followed by sunny days while 80% of cloudy days are followed by cloudy days. A local hotdog vendor makes, on average, $300 on sunny days and $100 on cloudy days. Assume you want to build a Markov model that you can use to answer questions b., c., d., and e. below. a. Define the states of the system and give the one-step transition probability matrix. b. If today is sunny, what is the probability it is sunny 5 days from now
Answer:
a) Sunny Cloudy
T = [ 0.9 0.2 ] Sunny
[ 0.1 0.8 ] Cloudy
b) 0.72269
Step-by-step explanation:
Given that;
90% of all sunny days are followed by sunny days while 80% of cloudy days are followed by cloudy days;
i.e if today is sunny (90%), the next day is sunny so its 10% cloudy
and if today is cloudy (80%), the next day is cloudy so its 20% sunny
a)
Now let T be the transition probability matrix which is expressed as;
Sunny Cloudy
T = [ 0.9 0.2 ] Sunny
[ 0.1 0.8 ] Cloudy
b)
If today is sunny, to find the probability that it will be sunny in 5 days from now = P^5.x where x = [ 1 ] sunny
[ 0 ] cloudy
so
p^5X = P.P.P.P.P.x
P.x = [ 0.9 0.2 ] [ 1 ] = [ 0.9 ]
[ 0.1 0.8 ] [ 0 ] [ 0.1 ]
(P^2).x = [ 0.9 0.2 ] [ 0.9 ] = [ 0.83 ]
[ 0.1 0.8 ] [ 0.1 ] [ 0.17 ]
(P^3).x = p(p^2)x = [ 0.9 0.2 ] [ 0.83 ] = [ 0.781 ]
[ 0.1 0.8 ] [ 0.17 ] [ 0.219 ]
(P^4).x = p(p^3)x = [ 0.9 0.2 ] [ 0.781 ] = [ 0.7467 ]
[ 0.1 0.8 ] [ 0.219 ] [ 0.2533 ]
(P^5).x = p(p^4)x = [ 0.9 0.2 ] [ 0.7467 ] = [ 0.72269 ]
[ 0.1 0.8 ] [ 0.2533 ] [ 0.27731 ]
so (P^5).x = [ 0.72269 ] sunny
[ 0.27731 ] cloudy
therefore the probability that it is sunny 5 days from is 0.72269

Jason ordered 239,021 pounds of flour to be used in his 25 bakeries . The company
Delivered the flour showed up with 451,202 pounds how many extra pounds of flour
Were delivered
So, it says that he ordered 239,021 pounds of flour, but they delivered 451,202 pounds. You are going to subtract the delivered amount to the ordered amount.
451,202 - 239,021 = _________
_________ = The Extra Amount Delivered
451,202 - 239,021 = 212,181
That means, that they had delivered 212,181 extra pounds of flour.

Answer:
The answer is D.
Step-by-step explanation:
130 x 60 = 7,800 miles. you don't need the extra information "5 days a week" to solve the problem.
The equation is y = 26x and the number of miles he drives in 60 work days will be 1560 miles. Then the correct option is B.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
Mr. Arnold drives 130 miles round trip to work 5 days a week.
Let x be the number of weeks and y be the total number of miles. Then the equation is given as,
y = 130x
y = 26x
Then the number of miles he drives in 60 work days will be
y = 26 (60)
y = 1560 miles
The equation is y = 26x and the number of miles he drives in 60 work days will be 1560 miles. Then the correct option is B.

The length of each side of the cardboard box is______
ft.
Answer:
The answer is
[tex] \frac{5}{2} \: \: \: feet \\ [/tex]Step-by-step explanation:
Since the cardboard box is a cube all it's sides are equal
Volume(V) of a cube = l³
where l is the length of one side
From the question
[tex]V = \frac{125}{8} \: {ft}^{3} [/tex]
The length of each side of the cardboard box is
[tex] {l}^{3} = \frac{125}{8} \\ \sqrt[3]{ {l}^{3} } = \sqrt[3]{ \frac{125}{8} } \\ l = \frac{5}{2} [/tex]
We have the final answer as
[tex] \frac{5}{2} \: \: \: feet \\ [/tex]
Hope this helps you
Answer:
5/2 ft
Step-by-step explanation:
The volume of a cube is calculated by the following formula.
Rewrite the formula in terms of the side, as shown.
It is given that the volume of the cardboard box is ft3. Substitute this value into the equation to determine the length of each side of the cardboard box.
Therefore, the length of each side of the cardboard box is 2.5 ft.
Which information can always be read directly from an equation written in point-slope form?
-The location of a point on the line.
-The location of the y-intercept.
-The location of the 2-intercept.
-The location of 2 (x, y) coordinate points.
Answer:
The location of a point on the line
Step-by-step explanation:
Generally, we can write an equation in the point slope form as follows;
y-y1 = m(x-x1)
Where m is the slope of the line
So looking at the option, we can easily see that the information we can read directly from the point-slope form is the location of a point on the line.
We can easily tell the value of (x1,y1) which easily gives out the location of that point on the line
