The characteristic of an experiment where the binomial probability distribution is applicable is that exactly two outcomes are possible on each trial.
What is the binomial probability distribution?
The binomial probability distribution is a probability model that is used to evaluate the probability of having an exact number of successes in a particular number of independent trials that have two possible outcomes (success and failure).
The characteristics of an experiment where the binomial probability distribution is applicable are as follows: It is an experiment that comprises a set of trials with a fixed number of independent trials.
It has only two outcomes, namely success and failure. The trials are independent of each other.
The probability of success is constant for each trial of the experiment.
The binomial distribution has a discrete set of outcomes. Each of these outcomes is measured by a single random variable that takes on only one of two possible values. Exactly two outcomes are possible on each trial. The experiment is a random variable that can be counted by counting the number of successes (X) in n trials.

(N+3)!÷n+ =(n+1)(n+2)(n+3)
Answer:
True
Step-by-step explanation:
A factorial means a number multiplied by all of the positive integers before it. That means both n+3! and n! have a common factor of n!. When you take out this factor of N, the fraction (n+3)!/n! ‘s denominator would be one, and the numerator would have all of the positive integers before n+3 and also being greater than n. Thus, (n+1)(n+2)(n+3)

center is located at (-2,5) is:(x+2)^2 / 36 + (y-5)^2 / 64 = 1
The dimensions of the given ellipse are major axis 12 units long and parallel to the y-axis, minor axis 8 units long, and the center is located at (-2,5).Let us find the standard form equation of the ellipse. The standard form equation of an ellipse is given by:(x-h)^2 / a^2 + (y-k)^2 / b^2 = 1Where (h, k) is the center of the ellipse, a is the distance from the center to either the x-axis or the y-axis, and b is the distance from the center to the other axis. Therefore, for the given ellipse, the equation of the ellipse in standard form is:(x+2)^2 / 36 + (y-5)^2 / 64 = 1Thus, the standard form equation of the ellipse whose major axis is 12 units long and parallel to the y-axis, minor axis 8 units long, and center is located at (-2,5) is:(x+2)^2 / 36 + (y-5)^2 / 64 = 1.

(a) What is the probability that exactly 7 patients will arrive during a 90 minutes period? (b) What is the probability that at least 30 minutes will pass until the next patient arrives? (c) If one hour has passed and no patient has arrived, what is the probability that the next patient arrives during the following 20 minutes? Problem 4: [9 points] Patients arrive at a hospital emergency department according to a Poisson distribution with an average of 9 per hour. (a) What is the probability that exactly 7 patients will arrive during a 90 minutes period? (b) What is the probability that at least 30 minutes will pass until the next patient arrives? (c) If one hour has passed and no patient has arrived, what is the probability that the next patient arrives during the following 20 minutes?
The probability that the next patient arrives during the following 20 minutes is approximately 0.776.
(a) The probability that exactly 7 patients will arrive during a 90-minute period can be found by using the Poisson distribution formula.Poisson distribution formula:P(X = x) = (e-λ * λx) / x!Where: λ is the average number of events per unit of time or space, x is the number of occurrences, e is the exponential constant equal to 2.71828.x! means x factorial that is x(x − 1)(x − 2)⋯(2)(1).Here, λ = 9/60 = 0.15 (since there are 9 arrivals in one hour, there would be 9/60 arrivals in 1 minute)We are to find the probability of exactly 7 patients arriving in 90 minutes.The time period is 90/60 = 1.5 hours. Hence, λ = 0.15 × 1.5 = 0.225P(X = 7) = (e-λ * λ7) / 7! = (e-0.225 * 0.2257) / 7! = 0.085 ≈ 0.09Therefore, the probability that exactly 7 patients will arrive during a 90 minutes period is approximately 0.09(b) We can calculate the probability of at least 30 minutes passing until the next patient arrives by using the cumulative distribution function (CDF) of the exponential distribution.Exponential distribution formula:f(x) = λe-λxwhere λ is the rate parameter, x is the time period, and e is the exponential constant equal to 2.71828.The mean waiting time between two successive arrivals is 60/9 = 6.67 minutes.Hence, λ = 1/6.67 = 0.15The probability of at least 30 minutes passing until the next patient arrives can be calculated as follows:P(X > 0.5) = 1 - P(X ≤ 0.5) = 1 - (1 - e-λx) = e-λx = e-0.15×0.5 ≈ 0.776Therefore, the probability that at least 30 minutes will pass until the next patient arrives is approximately 0.776.(c) The probability that the next patient arrives during the following 20 minutes can be calculated as follows:P(X > 1) = 1 - P(X ≤ 1) = 1 - (1 - e-λx) = e-λx = e-0.15×1/3 ≈ 0.776Therefore, the probability that the next patient arrives during the following 20 minutes is approximately 0.776.

Step-by-step explanation:
substitute the values into the cosine rule:
(2[tex]\sqrt{7}[/tex])² = ((2x - 1)² + (2x + 1)²) - 2(2x - 1)(2x + 1)cos(60))
work out each part separately:
(2[tex]\sqrt{7}[/tex])² = 28
(2x - 1)² = 4x² - 4x + 1
(2x + 1)² = 4x² + 4x + 1
(2x - 1)² + (2x + 1)² = (4x² - 4x + 1) + (4x² + 4x + 1) = 8x² + 2
2((2x - 1)(2x + 1)cos(60)):
(2x - 1)(2x + 1) = 4x² - 1
cos(60) = √1/2 = 1/2
2(4x² - 1)(1/2) = 4x² - 1
substitute back in:
28 = (8x² + 2) - (4x² - 1)
28 = 4x² + 3
25 = 4x²
25/4 = x²
x = √(25/4)

Answer:
To find the volume of a rectangular prism, we need to know the length, width, and height of the prism. However, the height is not given in the problem, so we cannot calculate the volume.
We can use the surface area and given dimensions to set up an equation to solve for the height. The surface area of a rectangular prism is given by:
SA = 2lw + 2lh + 2wh
where l, w, and h are the length, width, and height of the prism, respectively. We are given that the surface area is 62 square feet, and the width and length are 2 and 5 feet, respectively. Substituting these values into the surface area equation, we get:
62 = 2(2)(5) + 2(5)h + 2(2)h
62 = 20 + 14h
42 = 14h
h = 3
Now that we have found the height of the rectangular prism, we can calculate its volume. The volume of a rectangular prism is given by:
V = lwh
Substituting the given dimensions and calculated height, we get:
V = (5)(2)(3)
V = 30
Therefore, the volume of the rectangular prism is 30 cubic feet.
Step-by-step explanation:
Answer:
[tex]30ft^3[/tex]
Step-by-step explanation:
Surface area of a rectangular prism is A = 2(wl +hl +hw)
Volume, height, and Width is given now we can solve for l, v
[tex]A = 2(wl + hl + hw)\\62ft^2 = 2(2ft * l + 5ft * l + 5ft * 2ft)\\62ft^2 = 2(2lft + 5lft + 10ft^2)\\62ft^2 = 2(7lft + 10ft^2)\\62ft^2 = 14lft + 20ft^2\\14lft = 42ft^2\\l = 3ft[/tex]
Now that we have the length, we can solve for the volume
Volume of a rectangular prism = Length x Width x Height
[tex]V = 3ft * 2ft * 5ft\\ = 30ft^3[/tex]

The elongation α
of a planet is the angle formed by the planet, earth, and sun. It is known that the distance from the sun to Venus is 0. 723AU
(see Exercise 65 in Section 6. 2 ). At a certain time the elongation of Venus is found to be 39. 4∘.
Find the possible distances from the earth to Venus at that time in Astronomical Units (AU)
The possible distances from the Earth to Venus at the time of an elongation of 39.4 degrees are 0.709 AU and 1.333 AU.
The elongation of a planet is the angle formed when the planet, Earth, and Sun are in a straight line. At a certain time, the elongation of Venus was found to be 39.4 degrees. To find the possible distances from the earth to Venus at that time in Astronomical Units (AU), the Law of Cosines can be used.
The Law of Cosines states that for a triangle with sides a, b, and c and angles A, B, and C, c2 = a2 + b2 - 2abcosC.
In this case, a is the distance from the sun to Venus (0.723 AU), b is the distance from the Earth to Venus, and C is the elongation (39.4 degrees).
Therefore, b2 = 0.7232 + b2 - 2(0.723)(b)cos39.4.
Solving for b, we get b = 0.709 AU and b = 1.333 AU, so the possible distances from the Earth to Venus are 0.709 AU and 1.333 AU.

In both formulas x is the year, where x=0 corresponds to September 1998. Assuming these trends continue, estimate the year when the population of West Goma will equal the population of East Goma.A. 2009B. 1987C. 2008D. 11
In September 1998, the population of the country of West Goma in millions was modeled by f(x)=16.9e0.001x. The population of East Goma in millions was modeled by g(x)=13.8e0.019x. In both formulas, x is the year, where x=0 corresponds to September 1998.
To find the year when the population of West Goma will equal the population of East Goma, we will use the following method:
$$f(x)=g(x)$$
$$16.9e^{0.001x} = 13.8e^{0.019x}$$
Taking natural logarithms of both sides we have,
$$\ln(16.9) + 0.001x = \ln(13.8) + 0.019x$$
$$0.018x = \ln(16.9) - \ln(13.8)$$
$$x = \frac{1}{0.018}(\ln(16.9) - \ln(13.8))$$
$x \approx 41.06$, which corresponds to September 2039.
Therefore, the year when the population of West Goma will equal the population of East Goma is September 2039. Option E. 2039 is the correct answer.
Note: The growth rate of West Goma is smaller than that of East Goma, hence it will take a longer time to equalize.

Answer:
C, E
Step-by-step explanation:
You want to identify the true statements about the end behavior, symmetry, domain, and range of g(x) = -5x² and f(x) = 5x-10.
End behaviorThe function g(x) is of even degree (the exponent is 2), and the function f(x) is of odd degree (the exponent is 1). An even-degree function cannot have the same end behavior as an odd-degree function.
RangeThe range of any odd-degree polynomial function is (-∞, +∞).
Any even-degree polynomial function will have a global maximum or minimum so cannot have the same range. The range of g(x) is (-∞, 0].
DomainThe domain of any polynomial function is "all real numbers." Both f and g have the same domain.
SymmetryAn even-degree function may have an axis of symmetry. An odd-degree function cannot be symmetrical about any line. The functions cannot have the same symmetry.
Points of intersectionTwo polynomial functions may have a number of points of intersection equal to the highest degree. That means a degree-1 and a degree-2 function may have up to 2 points of intersection. These two functions intersect twice, as the graph in the attachment shows.
What are the solutions to the system of equations below?
7x - 5y = 38
2x+10y = -12
Answer:
Step-by-step explanation:
To solve this system of equations, we can use either substitution or elimination method.
Let's use the elimination method to eliminate y.
Multiplying the first equation by 2 and the second equation by 5, we get:
14x - 10y = 76
10x + 50y = -60
Now, we can add the two equations to eliminate y:
(14x - 10y) + (10x + 50y) = 76 - 60
Simplifying the left side and right side, we get:
24x = 16
Dividing both sides by 24, we get:
x = 2/3
Now that we have the value of x, we can substitute it back into either of the original equations to find y.
Let's substitute it into the first equation:
7x - 5y = 38
7(2/3) - 5y = 38
Simplifying and solving for y, we get:
-5y = 38 - 14/3
-5y = 100/3
y = -20/3
Therefore, the solution to the system of equations is (x, y) = (2/3, -20/3).

Debt ratio = 5800/9000
=58/90 = 29/45
2. Acceptable ratio is less than 43%
Is 29 out of 45 less than 43%
Convert 29/45 to percentage
29/45 /100/1 = 64.44%
You have exceeded acceptable ratio at 64.4%
Answer:
Your debt ratio is the percentage of your credit limit that you have spent.
spent $9000- $3200 = $5800
Debt to income ratio = 5800/9000 = 58/90 = 29/45
2. A satisfactory ratio is less than 43%.
Is 29 percent of 45 less than 43%?
29/45 converted to a percentage 29/45 /100/1 = 64.44%

Incorrect Your answer is incorrect. Find the midpoint M of the line segment joining the points C = (0, 8) and D = (-8, -8). D M-D = 00 X
The midpoint of the line segment joining the points C and D is M = (-4, 0).
How to calculate the midpoint MThe coordinates of the midpoint M of the line segment joining the points C = (0, 8) and D = (-8, -8) can be found using the midpoint formula:
M = ((x1 + x2)/2, (y1 + y2)/2)
So, for C = (0, 8) and D = (-8, -8), we have:
M = ((0 + (-8))/2, (8 + (-8))/2)
M = (-4, 0)
Therefore, the midpoint of the line segment joining the points C and D is M = (-4, 0).

Which set of measurements would prove that Δ
ABC and Δ
DEF are similar?
Triangle A B C has side A B of length 9, side A C of length 12, and the angle between them 35 degrees. Triangle D E F has no measures given.
A. DE = 15, EF = 20 and m∠D = 35
B. DE = 16, DF = 21 and m∠D = 35
C. DE = 12, DF = 16 and m∠D = 35
D. DE = 18, EF = 24 and m∠D = 70
Therefore , the solution of the given problem of triangle comes out to be DE = 15, EF = 20, and m∠D = 35, so the solution is A.
What exactly is a triangle?A triangle is a polygon because it has two or more additional parts. It has the simple form of a rectangle. A triangle can only be distinguished from a conventional triangle by its three sides, A, B, but not C. So when borders are still not exactly collinear, Euclidean geometry results in a single area as opposed to a cube. Three edges and three angles are the characteristics of triangles.
Here,
We must demonstrate that the respective sides and angles of two triangles are proportional in order to establish their similarity.
We are aware of the lengths of two of the sides and one of the angles in the triangular ABC. The third side's length can be determined using the Law of Cosines:
=> BC² = AB² + AC² - 2ABACcos(35°)
=> 9² + 12² - 2912*cos(35°) = BC²
=> BC ≈ 8.455
The edges of triangle ABC are therefore AB = 9, AC = 12, and BC 8.455.
=> A. DE=15, EF=20, and m=35
The angle measurement is 35 degrees, which corresponds to the angle in the triangular ABC. If the ends are proportionate, we can verify this:
=> DE/AB = 15/9 = 1.67
=> EF/AC = 20/12 ≈ 1.67
This collection of measurements meets the requirements for the triangles to be similar because the ratios are equal.
=> DE = 15, EF = 20, and m∠D = 35, so the solution is A.

A container holds 3.5 ounces of tablets. How many grams does the container hold?
The container holds 99.223 grams of tablets.
How to convert ounces to grams?One-sixteenth of a pound is represented by the weight measurement called an ounce (oz). A slice of bread and a pencil are two items that weigh about one ounce. One fluid ounce is the same as one-eighth of a cup in terms of volume. A medication cup has a volume of roughly one liquid ounce.
To convert ounces to grams, we can use the conversion factor 1 oz = 28.3495 g.
So, the container holds:
[tex]$3.5\ \text{oz} \times 28.3495\ \frac{\text{g}}{\text{oz}} = 99.223\ \text{g}$[/tex]
Therefore, the container holds 99.223 grams of tablets.
