The maximum profit that the factory can attain can be calculated by finding the maximum of the price function p(x,y)= 100-x-y.
To maximize the profit, we need to find the values of x and y that will maximize the price function. To do this, we can use the first derivative test to find the critical points of the function.
Differentiate the price function with respect to x and y, we obtain
p'(x) = -1
p'(y) = -1
Setting both derivatives to zero and solving for x and y, we obtain x= y= 100
To check if this is a maximum, we use the second derivative test.
Differentiate the price function again with respect to x and y, we obtain
p''(x) = 0
p''(y) = 0
Since both second derivatives are equal to 0, this is a point of inflection, and not an absolute maximum. Therefore, we need to check the boundary.
Since x and y must be positive, the boundary would be x=0 and y=0.
Substituting these values into the price function, we obtain
p(0,0) = 100
Therefore, the maximum profit the factory can attain is 100, when x=0 and y=0.

What is equation?An equation is a mathematical expression that shows the relationship between two values or variables. It typically consists of an equal sign (=), two expressions separated by an operator, and sometimes additional symbols like parentheses, fractions, or exponents. Equations are used to describe physical laws and conditions, solve problems, and make predictions. For example, the equation for the area of a rectangle is A = lw, where A is the area, l is the length, and w is the width.
This is because the eigenvalue of A which corresponds to the coefficient of a1(t) is 4, so the equation should contain e4t. The initial condition is a1(0) = 0, since the initial value of a1(t) is 0.

let x be a continuous random variable. we know that it takes values between 0 and 3, but we do not know its distribution or its mean and variance. we are interested in estimating the mean of x, which we denote by h. we will use 1.5 as a conservative value (upper bound) for the standard deviation of x. to estimate h, we take n i.i.d. samples x1,x2,...,xn, which all have the same distribution as x, and compute the sample mean
The randomized variable's sample distribution would be as follows: H+/- 1.96 * √3)/√n
A random variable in mathematics would be a variable for whom the value is the numerical result of an unpredictable event and a random number generator X on a sample space. S denotes the rule that gives each of the outcomes S in a collection a numerical value.
In this case, we have assumed that x is a constant random variable with values ranging from 0 to 3, but we are unsure of its distribution, mean, or variance.
The mean of x, which we designate by the letter h, is what we're now interested in estimating. To provide a conservative estimate (upper bound), we'll choose 1.5 for the standard deviation of x.
In this case, we must estimate h. To do this, we select the sample size n, the samples x1, x2,.., xn, all of which share the same dissemination as x, and accurately measure the sample mean.
Therefore, we have used a normal distribution to determine the variation of x as (0,6),

Los Angeles workers have an average commute of 27 minutes. Suppose the LA commute time is normally distributed with a standard deviation of 15 minutes. Let X represent the commute time for a randomly selected LA worker. Round all answers to 4 decimal places where possible.
a. What is the distribution of X? X ~ N(,)
b. Find the probability that a randomly selected LA worker has a commute that is longer than 35 minutes.
c. Find the 70th percentile for the commute time of LA workers. minutes
(a) Distribution of X is a bell curve with mean of 27 min
(b) The probability of a randomly selected LA worker has a commute that is longer than 35 minutes is 79.81%
(c) 70th percentile for the commute time of LA workers is 34.866
Given,
Mean = 27 minutes
Standard Deviation = 15 minutes
a. The distribution is a bell curve, with the peak of the curve corresponding to the mean = 27 minutes.
b. We have to find the probability that a randomly selected LA worker will have a commute of over 35 minutes. This value will fall on the right hand side of the bell curve, i.e, on the right side of the mean. For that, we need to find the z-score for 35.
z score, z = [tex]\frac{35-27}{15} = 0.53[/tex]
Using the z-tables, we get the z-value to the left of 0.53 as 0.2019, and therefore, the z-value to the right will be 1 - 0.2019 = 0.7981, which gives us a probability percentage of around 79.81%.
c. Here, we have to find the 70th percentile for the commute time for the LA workers. Let us take the marker as 0.70 on the bell-curve, so a z-score that gives us a value of 0.70 should be the right answer.
The answer to that is 0.5244.

The length of an interval of time such that the probability that no messages arrive during this interval is 0.94 is 56.88 seconds.
We have to find the length of the time interval that the probability of no messages arrive during this interval is 0.94
Let X be the no.of messages arrive to the server
X follows the poisson distribution with mean λ = 17
Let t be the time interval
The probability of no messages arrive during this interval is 0.94
Then P(0) = 0.94
e⁻⁽λt⁾ = 0.94
λt = ln0.94
17 t = ln(0.94)
t = ln(0.94)/17
t = 0.026872 / 17 hrs
t = 0.0158
Convert 0.0158 hours to seconds
That is t=0.0158(60)(60)

How to obtain the differential equations for a circle?The equation of a circle of center (h,k) and radius r is given as follows:
(x - h)² + (y - k)² = r².
The equation can be arranged to isolate the variable y as follows:
(y - k)² = r² - (x - h)²
y - k = square root (r² - (x - h)²)
y = square root (r² - (x - h)²) + k
To obtain the differential equation, then this equation must be differentiated towards variable x as follows:
[tex]\frac{dy}{dx} = \frac{d}{dx}(\sqrt{r^2 - (x - h)^2} + k)[/tex]
Applying the chain rule, along with the derivative for the square root, we have that:
[tex]\frac{d}{dx}(\sqrt{r^2 - (x - h)^2} + k) = -\frac{x - h}{\sqrt{r^2 - (x - h)^2}}[/tex]

In each part, find the two unit vectors in R^2 that satisfy the given conditions:
The two unit vectors parallel to the line y=5x+5 are: _ and _
The two unit vectors parallel to the line 2x+4y=1 are: _ and _
The two unit vectors perpendicular to the line y=2-5x are: _ and _
The two unit vectors parallel to the line y=5x+5 are [tex]u_{+}[/tex] =⟨1, 5⟩/√26 and [tex]u_{-}[/tex] =⟨1, 5⟩/√26.
What are vectors?Vectors, in Maths, are objects which have both, magnitude and direction. Magnitude defines the size of the vector. It is represented by a line with an arrow, where the length of the line is the magnitude of the vector and the arrow shows the direction.
Part A:
The given equation of line is y=5x+5.
It's all about slope. The vectors parallel to the line must have the same slope as the line. The line here is y=5x+5., and has slope 5. We can say the rise is 5 and the run is 1 and write the vector.
[tex]u_{\pm}[/tex] =⟨1, 5⟩
Magnitude =|u| =√(1²+5²)
= |±√26|
= √26
So, the two unit vectors are
[tex]u_{+}[/tex] =⟨1, 5⟩/√26 and [tex]u_{-}[/tex] =⟨1, 5⟩/√26
Part B: 2x+4y=1
x+2y=1/2
y=-x/2+1/4
Here slope is -1/2, where rise is -1 and run is 2
[tex]u_{+}[/tex]= ⟨2, -1⟩ and [tex]u_{-}[/tex]= ⟨-2, 1⟩
Magnitude =|u| =√(2²+(-1)²)
= √5
So, the two unit vectors are
[tex]u_{+}[/tex] =⟨2, -1⟩/√5 and [tex]u_{-}[/tex] =⟨-2, 1⟩/√5
Part C: The given equation is y=2-5x
Here slope is -5, slope perpendicular to line is -1/5
So, rise is -1 and run is 5
[tex]u_{\pm}[/tex] =⟨5, -1⟩
Magnitude =|u| =√(5²+(-1)²)

based on his past record, luke, an archer for a college archery team, has a probability of 0.90 of hitting the inner ring of the target with a shot of the arrow. assume that in one practice luke will attempt 5 shots of the arrow and that each shot is independent from the others. let the random variable x represent the number of times he hits the inner ring of the target in 5 attempts. the probability distribution of x is given in the table. P(X) 0 000001 0,00045 0.00810 0.07290 03280S 0.59049
What is the probability that the number of times Luke will hit the inner ring of the target out of the 5 attempts is less than the mean of X?
(A) 0.40951
(B) 0.50000
(C) 0.59049
(D) 0.91854
(E) 0.99144
The probability that Luke will touch the target's inner ring fewer times than the mean of X out of five attempts is 0.40951.
What is probability ?Probability refers to possibility.
A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
You will understand the potential outcomes for a random experiment using this fundamental theory of probability, which is also applied to the probability distribution.
Knowing the total number of outcomes is necessary before we can calculate the likelihood that a specific event will occur.
According to our question-
P(target) equals 0.90
Let the random variable X stand in for the number of times the arrow is fired at the target's ring.
The probability distribution of X is
x: 0 1 2 3 4 5
P(x): 0.00001 0.00045 0.00810 0.07290 0.32805 0.59049
Hence, The probability that Luke will touch the target's inner ring fewer times than the mean of X out of five attempts is 0.40951.

indicate if dijkstra's algorithm will be able to find the shortest path for this particular graph. (assume the source vertex is m) yes no it will loop forever the algorithm will never start
By using Dijkstra's algorithm, it can be concluded that-
It will loop forever.
Third option is correct
What is Dijkstra's algorithm?
Dijkstra's algorithm is used to find the shortest path between the nodes of a graph.
Here, a node is fixed which is called the source node and the distance from the source node to all other nodes are calculated.
The minimum distance gives the shortest path.
For the first option,
The first option is incorrect because the shortest path will not be obtained. There does not exist path between every pair of vertices
For the second option
The second option is incorrect because all the conditions of Dijkstra's algorithm are fulfilled but here, infinite looping takes place.
For the fourth option
The fourth option is incorrect because there exist a path between the point M and every other vertex in the graph.
So the third option is correct
