The shortest waiting time that would still place a patient in the longest 5% of waiting times is approximately 415.4 days.

To find the shortest waiting time that would place a patient in the longest % of waiting times, we need to determine the z-score corresponding to that percentile and then convert it back to the waiting time using the mean and standard deviation.

The longest % of waiting times can be interpreted as the upper tail of the distribution. If we assume the longest % is x%, then the corresponding z-score can be found using the formula:

z = invNorm(1 - x/100)

Let's say the longest % is 5%. Plugging in the values, we get:

z = invNorm(1 - 5/100) = invNorm(0.95)

Using a standard normal distribution table or calculator, we find that invNorm(0.95) ≈ 1.645.

Now we can convert the z-score back to the waiting time using the formula:

x = mean + z * standard deviation

Let's assume the mean waiting time is 365 days and the standard deviation is 30 days. Plugging in the values, we get:

x = 365 + 1.645 * 30 ≈ 415.35

Rounding to the nearest tenth, the shortest waiting time that would still place a patient in the longest 5% of waiting times is approximately 415.4 days.

The x - intercepts of the equation is x = 0

X - intercept refers to the value of x when y = 0

On a graph this refers to the value where the graph cuts the x axis

The given function is

y = ( 4x² - 36x ) / ( x - 9 )

equating y to zero and factorizing the function gives

0 = ( 4x² - 36x ) / ( x - 9 )

Jorge is incorrect since he is estimating the required number of cars using the incorrect methodology. Divide 22 by 4, and the outcome is not 5 with a remnant of 2, but rather 5 with a remainder of 2.

An individual or distinct unit is referred to as "unitary." The goal of this method is to establish values in terms of a single unit as a consequence. The unitary technique, for instance, can be used to calculate how many kilometers a car will travel on one litre of fuel if it currently goes 44 on two.

The following approach can be used to determine how many automobiles are required to carry the remaining passengers:

To determine the necessary number of full cars, divide the number of passengers still on board by each car's capacity: 22 passengers divided by four automobiles results in 5.5 autos.

Find the total required number of cars by rounding up to the next whole number: 6 cars.

Therefore, the answer is six cars will be required by the group to transport the remaining passengers.

The deadweight loss with a price ceiling of $30 would be $400.

First, we find the equilibrium price and quantity without the price ceiling. Set QD = QS and solve for P:
400 - 16P = -40 + 4P
20P = 440
P = 22
Plug P back into either the demand or supply equation to find the equilibrium quantity, Q:
Q = 400 - 16(22) = 248
Now, apply the price ceiling of $30 and find the new quantity demanded and supplied:
QD = 400 - 16(30) = 112
QS = -40 + 4(30) = 80
Since QS < QD, there is a shortage, and the actual traded quantity is 80. The deadweight loss is the difference between the equilibrium quantity and the traded quantity under the price ceiling:

At the price ceiling of $30, the quantity demanded would be 280 and the quantity supplied would be 200. This creates a shortage of 80 units and a deadweight loss of $400.
Deadweight loss = Q - QS = 248 - 80 = 168 units.

To find g'(x), the derivative of the function g(x) = sin(x), we can apply the differentiation rules for trigonometric functions. The derivative of sin(x) is cos(x). To determine the values of x for which g'(x) = 0, we set cos(x) = 0 and solve for x. The solutions to cos(x) = 0 correspond to the critical points of the function g(x).

The derivative of g(x) = sin(x) is g'(x) = cos(x). The derivative of sin(x) is derived using the chain rule, which states that if f(x) = sin(g(x)), then

f'(x) = cos(g(x)) * g'(x).

In this case, g(x) = x, so g'(x) = 1.

Therefore, g'(x) simplifies to cos(x).

To find the values of x for which g'(x) = 0, we set cos(x) = 0. The cosine function equals 0 at certain points in its period.

These points correspond to the x-intercepts of the cosine graph. The values of x for which cos(x) = 0 are x = π/2 + nπ, where n is an integer. These values represent the critical points of the function g(x).

Answer:

Step-by-step explanation:

Answer:

Find the least common denominator for both fractions and set up the fractions so they can both contain that same denominator.

Step-by-step explanation:

For example, let's say you want to add the fractions \(\frac{3}{4}\) and \(\frac{2}{7}\).

First, you will want to find the least common demoninator.  Write out the multiples for both denominators originally given, in this case 4 and 7.  Let's go up to 4*10 and 7*10:

4: 4,8,12,16,20,24,28,32,36,40

7: 7,14,21,28,35,42,49,56,63,70

Se which number in both sets is the first number to be the same in both sets.  That will be your least common denominator.  In this case, the least comon denominator is 28.

To set the fractions right, you would need to multiply the first fraction, 3/4, by 7/7: \(\frac{3}{4}*\frac{7}{7}=\frac{21}{28}\)

Then, you would need to multiply the second fraction, 2/7, by 4/4: \(\frac{2}{7}*\frac{4}{4}=\frac{8}{28}\)

Now, since both fractions have a common deonminator now, you can add them togther and simplify afterwards if you need to:

\(\frac{21}{28}+\frac{8}{28}=\frac{29}{28}=1\frac{1}{28}\)

And that's it.

The estimate of ∫e^x dx using rectangles with heights given by right-hand endpoints and four subintervals (n = 4) can be determined by evaluating the function at those endpoints and multiplying by the width of each rectangle.

Among the given options, the correct representation of the estimate is:

∫e^x dx is approximately (0.5)e^0.5 + (0.5)e^1 + (0.5)e^1.5 + (0.5)e^2.

This is because we divide the interval [0,2] into four subintervals of equal width, each with a width of 0.5. For the right-hand endpoint approximation, we evaluate the function e^x at those endpoints.

The height of each rectangle is given by e^x evaluated at the right-hand endpoint of each subinterval. The width of each rectangle is 0.5.

By multiplying the height and width of each rectangle and summing them up, we obtain the estimate of the integral.

Therefore, the correct representation is (0.5)e^0.5 + (0.5)e^1 + (0.5)e^1.5 + (0.5)e^2 as an estimate of ∫e^x dx using rectangles with right-hand endpoints and four subintervals.

A basis for the subspace of \($\mathbb{R}^3$\) spanned by \($S$\) is:

\($$\left\{\begin{pmatrix}1 \\2 \\4\end{pmatrix},\quad\begin{pmatrix}-1 \\3 \\4\end{pmatrix},\quad\begin{pmatrix}2 \\3 \\1\end{pmatrix}\right\}$$\)

To find a basis for the subspace of \(\mathbb{R}^3$ spanned by $S=\{(1,2,4),(-1,3,4),(2,3,1)\}$\), we need to find a set of linearly independent vectors that span the same subspace as \($S$\).

One way to do this is to use Gaussian elimination to reduce the matrix formed by the coordinates of the vectors in \($S$\) to row echelon form, and then to select the nonzero rows as the basis vectors.

First, we form the matrix:

\($$\begin{pmatrix}1 & -1 & 2 \\2 & 3 & 3 \\4 & 4 & 1\end{pmatrix}$$\)

Then we perform row operations to reduce the matrix to row echelon form:

\($$\begin{pmatrix}1 & -1 & 2 \\0 & 5 & -1 \\0 & 0 & -11\end{pmatrix}$$\)

We can see that there are three nonzero rows, which correspond to the first, second, and third columns of the original matrix, respectively. These nonzero rows are:

\($$\begin{pmatrix}1 \\2 \\4\end{pmatrix},\quad\begin{pmatrix}-1 \\3 \\4\end{pmatrix},\quad\begin{pmatrix}2 \\3 \\1\end{pmatrix}$$\)

These three vectors are linearly independent (to see this, we can observe that the reduced row echelon form of the original matrix has no zero rows, which implies that there are no nontrivial linear combinations of the vectors in \($S$\) that equal the zero vector), and they span the same subspace as \($S$\). Therefore, a basis for the subspace of \($\mathbb{R}^3$\) spanned by \($S$\) is:

\($$\left\{\begin{pmatrix}1 \\2 \\4\end{pmatrix},\quad\begin{pmatrix}-1 \\3 \\4\end{pmatrix},\quad\begin{pmatrix}2 \\3 \\1\end{pmatrix}\right\}$$\)
