suppose that x is the number of cars per minute that pass through a certain intersection, and that x has the poisson distribution. what can be the smallest value of x? enter your answer in accordance to the question statemententer your answer in accordance to the question statement
The smallest value of x in the Poisson distribution is 0, which means that no cars can pass through the intersection in a given minute.
For explain further, a Poisson distribution is a statistical model that describes the probability of a given number of events occurring in a fixed period of time, such as cars passing through an intersection in a minute.
In a Poisson distribution, the probability of x events occurring in a given minute is given by the equation P(x) = e-λλx/x!, where λ is the average number of events in a given minute. In this case, λ would be the average number of cars that pass through the intersection per minute.
The probability of 0 cars passing through the intersection in a given minute is e-λλ0/0! = 1, which is the highest probability in the distribution. Therefore, the smallest value of x in a Poisson distribution is 0.

Show your work, please
Slope (m) =
Answer:
To calculate the slope of the line that passes through the points (1, 2) and (-3, 5), we use the slope formula:
m = (Y2 - Y1) / (X2 - X1)
where (X1, Y1) = (1, 2) and (X2, Y2) = (-3, 5).
Substituting the values into the formula, we get:
m = (5 - 2) / (-3 - 1)
m = 3 / (-4)
Simplifying the fraction by dividing both the numerator and denominator by their greatest common factor of 1, we get:
m = -3/4
Therefore, the slope of the line in simplest form is -3/4.
What is the end behavior of function h? h(x)=-4x^2+11
We can conclude that the end behavior of the function [tex]$h(x)$[/tex] is that it approaches negative infinity as [tex]$x$[/tex] approaches either positive or negative infinity.
What is meant by end behavior?
End behavior refers to the behavior of a function as the input (usually denoted by x) becomes extremely large (approaches positive or negative infinity). It describes the trend of the function as the input approaches infinity or negative infinity, and is determined by the highest-degree term of the function.
To determine the end behavior of the function [tex]$h(x)=-4x^2+11$[/tex], we can use limits. Specifically, we can evaluate the limit of [tex]$h(x)$[/tex] as [tex]$x$[/tex] approaches positive infinity and as [tex]$x$[/tex] approaches negative infinity.
As [tex]$x$[/tex] approaches positive infinity, we have:
[tex]\lim_{x \to \infty} h(x)= \lim_{x \to \infty} (-4x^2+11) = - \infty[/tex]
This tells us that as [tex]$x$[/tex] gets larger and larger, the value of [tex]$h(x)$[/tex] becomes more and more negative, eventually approaching negative infinity.
Similarly, as [tex]$x$[/tex] approaches negative infinity, we have:
[tex]\lim_{x \to -\infty} h(x)= \lim_{x \to -\infty} (-4x^2+11) = - \infty[/tex]
This tells us that as [tex]$x$[/tex] gets more and more negative, the value of [tex]$h(x)$[/tex] becomes more and more negative, also approaching negative infinity.
Therefore, we can conclude that the end behavior of the function [tex]$h(x)$[/tex] is that it approaches negative infinity as [tex]$x$[/tex] approaches either positive or negative infinity.

A horizontal curve is to be designed with a 2000 feet radius. The curve has a tangent length of 400 feet and its pi is located at station 103+00. Determine the stationing of the PT.
A horizontal curve is a curve that is used to provide a transition between two tangent sections of a roadway. To connect two tangent road sections, horizontal curves are used. Horizontal curves are defined by a radius and a degree of curvature. The curve's radius is given as 2000 feet. The tangent length is 400 feet.
The pi is located at station 103+00.
To determine the stationing of the PT, we must first understand what the "pi" means. PC or point of curvature, PT or point of tangency, and PI or point of intersection are the three primary geometric features of a horizontal curve. The point of intersection (PI) is the point at which the back tangent and forward tangent of the curve meet. It is an important point since it signifies the location of the true beginning and end of the curve. To calculate the PT station, we must first determine the length of the curve's arc. The formula for determining the length of the arc is as follows:
L = 2πR (D/360)Where:
L = length of the arc in feet.
R = the radius of the curve in feet.
D = the degree of curvature in degrees.
PI (103+00) indicates that the beginning of the curve is located 103 chains (a chain is equal to 100 feet) away from the road's reference point. This indicates that the beginning of the curve is located 10300 feet from the road's reference point. Now we need to calculate the degree of curvature
:Degree of curvature = 5729.58 / R= 5729.58 / 2000= 2.8648 degrees. Therefore, the arc length is:
L = 2πR (D/360)= 2π2000 (2.8648/360)= 301.6 feet.
The length of the curve's chord is equal to the length of the tangent, which is 400 feet. As a result, the length of the curve's long chord is: Long chord length = 2R sin (D/2)= 2 * 2000 * sin(2.8648/2)= 152.2 feet To determine the stationing of the PT, we can use the following formula: PT stationing = PI stationing + Length of curve's long chord= 10300 + 152.2= 10452.2Therefore, the stationing of the PT is 10452+2.

why does the gcf of the variables of a polynomial have the least exponent of any variable term in the polynomial brainly
The GCF (Greatest Common Factor) of the variables of a polynomial has the least exponent of any variable term in the polynomial because it represents the largest factor that is common to all the terms in the polynomial.
To understand this better, consider a polynomial like 6x²y³ + 9x³y². The GCF of this polynomial would be 3x²y², which is the largest factor that can divide both terms evenly.
Notice that the exponent of each variable in the GCF is the smallest exponent among the corresponding variable terms in the polynomial.
This is because any factor that is common to all terms in the polynomial must be able to divide each term without leaving a remainder. Therefore, the exponent of each variable in the GCF must be less than or equal to the exponent of that variable in every term of the polynomial.
In summary, the GCF of the variables of a polynomial has the least exponent of any variable term in the polynomial because it represents the largest factor that can divide all terms in the polynomial evenly, and therefore, it must have the smallest exponent of each variable among all terms in the polynomial.

Answer:
11°
Step-by-step explanation:
The sum of the angles in a triangle is always 180°. Therefore, we can find the measure of ∠z by subtracting the measures of ∠x and ∠y from 180°:
∠z = 180° - ∠x - ∠y
∠z = 180° - 110° - 59°
∠z = 11°

To calculate the number of days it will take Ivan to read both books, we need to divide the total number of pages by the number of pages Ivan can read per day.
The first book has c pages, and the second book has d pages, so the total number of pages is c + d. If Ivan reads eight pages per day, then he will read a total of 8[tex]*[/tex]n pages in n days. Therefore, the number of days it will take Ivan to read both books can be calculated as: n = (c + d) / 8
This formula tells us that we need to divide the total number of pages by the number of pages Ivan can read per day, which is eight. The result of this division will give us the number of days it will take Ivan to read both books.
For example, if the first book has 100 pages and the second book has 200 pages, then the total number of pages is 300. plugging this into the formula, we get: n = (100 + 200) / 8 = 37.5 Since Ivan can't read a fraction of a day, we round up to the nearest whole number.

The side opposite to angle Y is the longest, and angle Y is the largest angle in triangle XYZ. So, the angles can be ordered from greatest to least as follows:
angle Y > angle Z > angle X.
What is triangle ?
A triangle is a three-sided polygon, or a closed two-dimensional shape with three straight sides and three angles. The sum of the angles in a triangle always adds up to 180 degrees. The sides of a triangle can be of different lengths, and the angles can be acute (less than 90 degrees), right (equal to 90 degrees), or obtuse (greater than 90 degrees).
To order the angles from greatest to least in triangle XYZ, we need to determine which side is the longest. By the Law of Cosines, we know that:
[tex]c^2 = a^2 + b^2 - 2ab*cos(C)[/tex]
where c is the side opposite to angle C, and a and b are the other two sides.
So, let's calculate [tex]c^2[/tex] for each angle:
For angle X: [tex]c^2 = 25^2 + 27^2 - 2(25)(27)*cos(X)[/tex] ≈ 173.65
For angle Y: [tex]c^2 = 24^2 + 27^2 - 2(24)(27)*cos(Y)[/tex] ≈ 267.43
For angle Z: [tex]c^2 = 24^2 + 25^2 - 2(24)(25)*cos(Z)[/tex] ≈ 121.97
Therefore, the side opposite to angle Y is the longest, and angle Y is the largest angle in triangle XYZ. So, the angles can be ordered from greatest to least as follows:
angle Y > angle Z > angle X

Can you help me with this
Answer:c
Step-by-step explanation:
Answer: C
Step-by-step explanation:
carlos and juan take 5 hours to do a job. carlos alone takes 8 hours to do the same job. how long would it take juan to do the same job alone?
13.33 hrs long would it take juan to do the same job alone.
Here, we have,
given that,
carlos and juan take 5 hours to do a job.
carlos alone takes 8 hours to do the same job.
let, x hr long would it take juan to do the same job alone.
now, we have,
1 hr work of carlos = 1/8
1 hr work of juan = 1/x
1 hr work of both = 1/8 + 1/x = (x+8)/8x
we have,
So they together can do this job in = 5 hours
so, ATQ, we get,
(x+8)/8x = 1/5
or, (5x+40) = 8x
or, 3x = 40
or. x = 13.33
Hence, 13.33 hrs long would it take juan to do the same job alone.
