An exponential distribution is formed by the waiting times for a patient in the emergency room. The average waiting time for this distribution is 38 minutes. Given that it has already taken 37 minutes, what is the probability that the wait time will be more than an additional 41 minutes? Round your answer to three decimal places.
Answer:
0.207 = 20.7% probability that the wait time will be more than an additional 41 minutes
Step-by-step explanation:
To solve this question, we should understand the exponential distribution and conditional probability.
Exponential distribution:
The exponential probability distribution, with mean m, is described by the following equation:
[tex]f(x) = \mu e^{-\mu x}[/tex]
In which [tex]\mu = \frac{1}{m}[/tex] is the decay parameter.
The probability that x is lower or equal to a is given by:
[tex]P(X \leq x) = \int\limits^a_0 {f(x)} \, dx[/tex]
Which has the following solution:
[tex]P(X \leq x) = 1 - e^{-\mu x}[/tex]
The probability of finding a value higher than x is:
[tex]P(X > x) = 1 - P(X \leq x) = 1 - (1 - e^{-\mu x}) = e^{-\mu x}[/tex]
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.
The average waiting time for this distribution is 38 minutes.
This means that [tex]m = 38, \mu = \frac{1}{38} = 0.0263[/tex]
Given that it has already taken 37 minutes, what is the probability that the wait time will be more than an additional 41 minutes?
Event A: Taking more than 37 minutes.
Event B: More than 37 + 41 = 78 minutes.
Probability of taking more than 37 minutes:
[tex]P(A) = P(X \leq 37) = 1 - e^{-0.0263*37} = 0.6221[/tex]
More than 37 minutes and more than 78 minutes:
The intersection is more than 78 minutes, so:
[tex]P(A \cap B) = P(X > 78) = e^{-0.0263*78} = 0.1286[/tex]
The probability is:
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.1286}{0.6221} = 0.207[/tex]
0.207 = 20.7% probability that the wait time will be more than an additional 41 minutes

You deposit $400 in an account. The account earns $72 simple interest in 6 years. What is the annual
interest rate?
The principal was $600.
Explanation:
Find principal by using the formula , where I is interest, P is total principal, i is rate of interest per year, and t is total time in years.
In this example I = $72, i = 4% and t = 3 years, so
Answer: 173,200
Step-by-step explanation:
This is very simple and I can help with this!!
Interest= Principal x Rate x Time
Interest = ($400)($72)(6)= 172,800+400= 173,200
The number of calories in a one ounce serving of a certain chicken sandwich is a random variable with mean 110 calories. The number of calories in a full cup of lemonade is a random variable with mean 140 calories. For lunch, you eat one ounce of the chicken sandwich and LaTeX: \frac{1}{2}1 2 cup of lemonade. Let K be the random variable that represents the total number of calories in this lunch. The mean of K is
Answer:
The mean of K is 180 calories.
Step-by-step explanation:
Mean of a sum of normal distribution:
The mean of a sum of normal distributions is the sums of the mean.
In this question:
Lunch:
One ounce of chicken sandwich, with mean 110 calories.
Half a cup of lemonade, with mean 140/2 = 70 calories.
Let K be the random variable that represents the total number of calories in this lunch. The mean of K is
110 + 70 = 180 calories
The mean of K is 180 calories.

Ted invests $6,082 in a retirement account with a fixed annual interest rate of 5% compounded continuously. What will the account balance be after 13 years?
Answer:
$11468.52
Step-by-step explanation:
Given data
Principal= $6,082
Rate= 5%
time= 13 years
The expression for compound interest is
A= P(1+r)^t
substitute
A=6082(1+0.05)^13
A=6082(1.05)^13
A=6082*1.885649
A=11468.52
Hence the Amount is $11468.52

Which pair of angles must be supplementary?
VX
2.
6
3
4
5
21 and 26
22 and 25
0 25 and 24
Z6 and 22
Answer:
∠1 and ∠6
Step-by-step explanation:
Supplementary angles are two or more angles added together make 90°.
Right angles indicated by the small square at the corners.
∠2 and ∠5 are right angles.
So, any pair with ∠2 and ∠5 are not supplementary.
The only pair of angles that are not associated with ∠2 and ∠5 is: ∠1 and ∠6.
For a given arithmetic sequence, the 75th term, a75, is equal to 342, and the 4th term, 24, is equal to - 13.

Find the value of the 32
term, 232
Answer:
The 32th term is 127.
Step-by-step explanation:
Arithmetic sequence:
In an arithmetic sequence, the difference between consecutive terms is always the same. The general equation for an arithmetic sequence is given by:
[tex]a_n = a_1 + (n-1)d[/tex]
In which d is the common difference.
It can also be written as:
[tex]a_n = a_m + (n - m)d[/tex]
75th term is equal to 342, and the 4th term, 24, is equal to - 13.
This means that [tex]a_4 = -13, a_75 = 342[/tex]. We use this to find d. So
[tex]a_{75} = a_4 + (75 - 4)d[/tex]
[tex]342 = -13 + 71d[/tex]
[tex]71d = 355[/tex]
[tex]d = \frac{355}{71}[/tex]
[tex]d = 5[/tex]
Find the value of the 32th term:
[tex]a_n = a_m + (n - m)d[/tex]
[tex]a_{32} = a_{4} + (32 - 4)d[/tex]
[tex]a_{32} = -13 + 28(5) = -13 + 140 = 127[/tex]
The 32th term is 127.

Complete question :
Wright et al. [A-2] used the 1999-2000 National Health and Nutrition Examination Survey NHANES) to estimate dietary intake of 10 key nutrients. One of those nutrients was calcium in all adults 60 years or older a mean daily calcium intake of 721 mg with a standard deviation of 454. Usin these values for the mean and standard deviation for the U.S. population, find the probability that a randonm sample of size 50 will have a mean: (mg). They found a) Greater than 800 mg b) Less than 700 mg. c) Between 700 and 850 mg.
Answer:
0.10935
0.3718
0.9778
0.606
Step-by-step explanation:
μ = 721 ; σ = 454 ; n = 50
P(x > 800)
Zscore = (x - μ) / σ/sqrt(n)
P(x > 800) = (800 - 721) ÷ 454/sqrt(50)
P(x > 800) = 79 / 64.205295
P(x > 800) = 1.23
P(Z > 1.23) = 0.10935
2.)
Less than 700
P(x < 700) = (700 - 721) ÷ 454/sqrt(50)
P(x < 700) = - 21/ 64.205295
P(x < 700) = - 0.327
P(Z < - 0.327) = 0.3718
Between 700 and 850
P(x < 850) = (850 - 721) ÷ 454/sqrt(50)
P(x < 850) = 129/ 64.205295
P(x < 700) = 2.01
P(Z < 2.01) = 0.9778
P(x < 850) - P(x < 700) =
P(Z < 2.01) - P(Z < - 0.327)
0.9778 - 0.3718
= 0.606

What is the slope of the line?
Answer:
Slope: -1
Step-by-step explanation:
(0, -2) and (1, -3)
m= (y2-y1)/(x2-x1)
m= (-3+2)/(1-0)
m= (-1)/(1)
m = -1
Find the equation of the line parallel to y=6 that contains the point (-1,1). Write the equation in slope intercept form
Given:
The equation of parallel line is [tex]y=6[/tex].
The line contains the point (-1,1).
To find:
The equation of the line.
Solution:
The slope intercept form of a line is:
[tex]y=mx+b[/tex]
Where, m is the slope and b is the y-intercept.
The equation of parallel line is
[tex]y=6[/tex]
It can be written as
[tex]y=(0)x+6[/tex]
The slope of this line is 0.
The slopes of two parallel lines are always equal. So, the slope of the required line is also 0. It passes through the point (-1,1) so the equation of the line is:
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-1=0(x-(-1))[/tex]
[tex]y-1=0[/tex]
[tex]y=1[/tex]
Therefore, the equation of the required line is 1.
How many notebooks do you think it would take to make a stack that is 5 feet high?
Answer:
There are total 30 books in the 5 feet high stack of books.
Step-by-step explanation:
The complete question is
Given, Each note book is 2 inches thick, How many notebooks do you think it would take to make a stack that is 5 feet high
Solution
Thickness of each book [tex]= \frac{2}{12} = \frac{1}{6}[/tex]
The total height of the book stack is [tex]5[/tex] feet.
The number of books in the stack is equal to total height of the stack divided by the thickness of one book
Number of books in five feet high stack is
[tex]\frac{5}{\frac{1}{6} } \\5 * \frac{6}{1} \\30[/tex]
Hence, there are total 30 books in the 5 feet high stack of books.

Answer
x=29
Step-by-step explanation:
Okay we know that the sum of all angles in a triangle is 180, so all we have to do is add them up first
(x+17)+(2x+5)=3x+22
(3x+22)+(3x-16)=6x+6
okay so we now know that 6x+6=180
subtract 6 on both sides 6x=174
then divide by 6 to get x=29
hope this helps!
