According to the given information, the correct answer is Bus 18, with a median of 13.

What is median?

The median is a measure of central tendency in statistics. It is the value that separates the dataset into two equal halves, with half the values being greater than the median and half being less than the median.

To compare the travel times of the two buses and determine which typically has the faster travel time, we need to look at the measures of central tendency.

The two common measures of central tendency are mean and median.

For Bus 18, the median is 13, which means that half of the students take less than 13 minutes to travel to school and half take more than 13 minutes. The mean can be calculated by finding the sum of all travel times and dividing by the number of students, but this information is not provided in the given line plot.

For Bus 47, the median is 16, which means that half of the students take less than 16 minutes to travel to school and half take more than 16 minutes. The mean can be estimated by calculating the average of all the travel times, which is:

(4+6+10+10+12+12+14+14+18+18+22+22+28+28+28)/15 = 16

Therefore, the mean travel time for Bus 47 is also 16.

Comparing the median travel times, we can see that Bus 47 has a higher median of 16 compared to Bus 18's median of 13. This suggests that the travel times for Bus 47 are typically longer than those for Bus 18, and therefore Bus 18 typically has the faster travel time.

Therefore, the correct answer is Bus 18, with a median of 13.

For the given ellipse, the height of the ceiling at the center is 5 meters.

From the properties of an ellipse, we know that the distance from the center to one of the foci is a, and the distance from the center to one of the vertices is b. We can find these values using the equation of an ellipse:

(x²/a²) + (y²/b²) = 1

At the center of the gallery, x = 0, and we know that the major axis length is 36 meters, so b = 18 meters. We can solve for a by using the fact that the distance between the two foci is 10 meters:

2a = 36 - 10 = 26

a = 13

Therefore, the distance from the center to one of the foci is 13 meters, and the distance from the floor to the same focus is 13 - 5 = 8 meters.

Thus, the height of the ceiling at the center of the gallery is 13 - 8 = 5 meters.

The base οf the triangle is 5 centimeters and the height οf the triangle is 20 centimeters.

In geοmetry, a triangle is a three-sided pοlygοn that cοnsists οf three line segments οr sides and three angles.

Let's denοte the base οf the triangle by "b" and the height by "h". We knοw that the area οf the triangle is 50 square centimetres, sο we can use the fοrmula fοr the area οf a triangle tο set up an equatiοn:

[tex]Area = (1/2) * base * height[/tex]

Substituting the given values, we get:

[tex]50 = (1/2) * b * h[/tex]

We also know that the height of the triangle is four times the base:

h = 4b

We can substitute this expression for "h" into the equation for the area:

[tex]50 = (1/2) * b * (4b)[/tex]

[tex]50 = 2b^2[/tex]

Dividing both sides by 2, we get:

[tex]25 = b^2[/tex]

Taking the square rοοt οf bοth sides, we get:

b = 5

Sο the base οf the triangIe is 5 centimeters. Using the expressiοn fοr the height in terms οf the base, we can find the height:

h = 4b = 4(5) = 20

Sο the height οf the triangIe is 20 centimeters.

Hence, the base οf the triangIe is 5 centimeters and the height οf the triangIe is 20 centimeters.

Answer:

(4, 1 )

Step-by-step explanation:

3x - 5y = 7 → (1)

2x + 5y = 13 → (2)

the 'best' or 'simplest' way to solve this system is the elimination method

since the signs of 5y are opposites then adding will eliminate the y term

add (1) and (2) term by term to eliminate y

(3x + 2x) + (- 5y + 5y) = 7 + 13 , that is

5x + 0 = 20

5x = 20 ( divide both sides by 5 )

x = 4

substitute x = 4 into either of the 2 equations and solve for y

substituting into (2)

2(4) + 5y = 13

8 + 5y = 13 ( subtract 8 from both sides )

5y = 5 ( divide both sides by 5 )

y = 1

solution is (4, 1 )

  (c)  AE = x·cos(α)/sin(θ)

  (d)  BD = x·cos(α)cos(α-θ)/cos(θ)

Step-by-step explanation:

In the given diagram, you want expressions for (c) AE and (d) BD in terms of x, α, and θ.

The law of sines can be used in ∆ACE to give the measure of AE.

[tex]\dfrac{AE}{\sin(C)}=\dfrac{CE}{\sin(\theta)}\\\\\boxed{AE=\dfrac{x\,\cos(\alpha)}{\sin(\theta)}}\qquad\text{where $\sin(C)=\cos(\alpha)$ and $CE=x$}[/tex]

The length BD can be found in terms of AD and θ:

  BD = AD·tan(θ)

The length AD can be found in terms of AE and (α-θ):

  AD = AE·cos(α-θ)

Using the value of AE from part (c), we have ...

  BD = AE·cos(α-θ)·tan(θ) = x·cos(α)cos(α-θ)·tan(θ)/sin(θ)

  BD = x·cos(α)cos(α-θ)/cos(θ) . . . . . . . using tan/sin = 1/cos

Simplify figure for understanding-

Answer:

-3x^3y^2 - 4x^2y + 8y.

Step-by-step explanation:

When we distribute the negative sign to the terms inside the parentheses, we get:

(2x^3y^2 − 8x^2y + 4y) − (5x^3y^2 − 4x^2y − 4y) = 2x^3y^2 − 8x^2y + 4y - 5x^3y^2 + 4x^2y + 4y

Now, we can combine like terms. The terms with x^3y^2 are 2x^3y^2 and -5x^3y^2, which combine to give -3x^3y^2. The terms with x^2y are -8x^2y and 4x^2y, which combine to give -4x^2y. The terms with y are 4y and 4y, which combine to give 8y. Therefore, we have:

(2x^3y^2 − 8x^2y + 4y) − (5x^3y^2 − 4x^2y − 4y) = -3x^3y^2 - 4x^2y + 8y

Therefore, the simplified expression is -3x^3y^2 - 4x^2y + 8y.

The expression can be simplified by subtracting the coefficients of matching terms from the first and second parentheses. The simplified expression is -3x3y2 - 4x2y + 8y.

To simplify the expression (2x3y2 − 8x2y + 4y) − (5x3y2 − 4x2y − 4y), you must subtract each term in the second parentheses from the corresponding term in the first. In this case, it works as follows:

So, the simplified expression becomes −3x3y2 − 4x2y + 8y.

Let μ = mean and σ = standard deviation of IQ scores in population.

Then we can write the two equations as :

⇒ P(X ≤ 80) = 0.13    ...equation(1)

⇒ P(X ≥ 128) = 0.03   ...equation(2)

we standardize the data by using the formula:

⇒ Z = (X - μ)/σ,

Where Z = standard normal variable.

Using the standard normal distribution, we know that P(Z ≤ -1.126) = 0.13,

So, -1.126 = (80 - μ)/σ   .....equation(3),

and we know that P(Z ≥ 1.881) = 0.03.

So, 1.88 = (128 - μ)/σ     ...equation(4),

⇒ μ = 128 - 1.881σ,

Solving equation(3) and equation(4),

We get,

⇒ σ ≈ 16.

Substituting σ = 16 into the equation(4),

The x-intercepts (zeros), end behaviors, degree and multiplicity of the function f(x) = (x - 2)²·(x + 1)·(x - 4), can be used to graph the polynomial in factored form. Please find attached the graph of the polynomial created with MS Excel.

A zero is an input variable value that makes the value of the output to be zero. A root is a value that satisfies the equation.

The steps to graph the polynomial in factored form are;

1. Find the x-intercepts; The x-intercepts are obtained by setting each  factor as being equivalent to zero and solve for x. The values obtained are the x-intercepts or the zeros of the function.

The specified function, f(x) = (x - 2)²·(x + 1)·(x - 4), the zeros are; x = 2, (with a multiplicity of 2), x = -1, and x = 4.

2. Determine the end behavior of the function: The degree and leading coefficient of a polynomial determines the end behavior of the polynomial.
The degree of a function is the highest exponent of the function. The highest exponent of x in the function f(x) is 4, therefore, the degree of f(x) is 4.

The leading coefficient is the coefficient of the term with the highest exponent of x. The leading coefficient of f(x) is therefore, the coefficient of the term with the highest exponent of x, which is 1

3. Determine the multiplicity of the zeros: The number of times a factor appears in the factored form determines the multiplicity of the zero of the factor.

The zero of x = 2 in the function has a multiplicity of 2 indicating that the graph touch and bounces upwards on the x-axis at x = 2.

4. Determine the behaviour at the x-intercepts: The multiplicity of the zero determines the behavior of the graph at the x-intercept, such that an odd multiplicity indicates that the graph crosses the x-axis and an even multiplicity indicates that the graph touches the x-axis and bounces upwards or downwards at the point.

The information in the steps 1 – 4 can then be used to sketch the graph of the polynomial.

P(A|B) = P(B|A) * P(A) / [P(B|A) * P(A) + P(B|not A) * P(not A)]

where P(B|A) is the probability of a positive test result given that the person has COVID-19, P(A) is the prevalence of COVID-19 in the population (0.083 or 8.3%), P(B|not A) is the probability of a positive test result given that the person does not have COVID-19 (false positive rate, 0.05 or 5%), and P(not A) is the complement of P(A) (0.917 or 91.7%).

Plugging in the values, we get:

P(A|B) = (0.98 * 0.083) / [(0.98 * 0.083) + (0.05 * 0.917)]

To create the figure with the new scale of 1 unit = 3 yd. The steps are mentioned below.

Scale refers to the proportional relationship between the measurements of an object or a system and the corresponding measurements on a representation or a model of that object or system. It is commonly used in many fields, including mathematics, engineering, architecture, art, and geography.

In mathematics, scale can be expressed as a ratio or a fraction, which indicates how much the measurements on the representation or model have been reduced or enlarged relative to the actual measurements of the object or system. For example, a scale of 1:100 means that every measurement on the representation or model is 100 times smaller than the corresponding measurement on the actual object or system.

In art and architecture, scale is used to create a sense of proportion and perspective in a work. For example, an artist might use a smaller scale for a background object to make it appear farther away, while using a larger scale for a foreground object to make it appear closer.

To create the figure with the new scale of 1 unit = 3 yd. Here are the steps:

If the sides of a right triangle are x, 3x+3, and 4x-3, the value of x is 7

In a right triangle, the Pythagorean theorem states that the sum of the squares of the two shorter sides equals the square of the longest side (the hypotenuse). Using this theorem, we can set up an equation as follows

x^2 + (3x+3)^2 = (4x-3)^2

Expanding the squares, we get

x^2 + 9x^2 + 18x + 9 = 16x^2 - 24x + 9

Simplifying and rearranging terms, we get

6x^2 - 42x = 0

Factorizing out x, we get

x(6x - 42) = 0

Therefore, x = 0 or x = 7. However, since the sides of the triangle cannot be zero, we must choose x = 7 as the solution.
