The domain of the function in the graph can be written as: -4 ≤ x < 4
or [-4, 4)
How to write the domain of the function?To identify the domain look at the horizontal axis. Remember that the domain is the set of the inputs, and the inputs go in the horizontal axis (or the x-axis)
You can see that there is a closed dot (which means that the value belongs to the domain) at x = -4, and there is a open dot (which means that the value does not belong to the domain) at x = 4.
Then the domain of the graph is:
-4 ≤ x < 4

The height of the building is approximately 78.63 meters.
The following is a step-by-step explanation of how to solve the problem. We'll need to use some trigonometric concepts and formulas to find the solution.
Draw a diagram of the situation described in the problem to get a better understanding of the problem. The diagram would have a right-angled triangle with angle of elevation of 66° at the bottom left vertex and another angle of elevation of 53° at the bottom right vertex. The object on top of the building is at the vertex of the triangle. Point M and I on the diagram are points on the horizontal line of sight and on the ground respectively. We can label the diagram with the following values:Angle of elevation from point A = 66°Angle of elevation from point P = 53° Length of line segment AM = h Length of line segment MP = x Length of line segment IP = y Length of line segment MT = 50m. We'll use these values to calculate the length of h, which is the height of the building.Use the tangent ratio to find x:tan 66° = h / x => x = h / tan 66°. Use the tangent ratio to find y:tan 53° = h / y => y = h / tan 53°.We know that x + y = 50, so substituting the expressions for x and y from step 3 gives:h / tan 66° + h / tan 53° = 50h = 50 tan 66° tan 53° / (tan 53° + tan 66°) ≈ 78.63 m.Therefore, the height of the building is approximately 78.63 meters.

Two datasets arranged in descending order are; {8,x , 4,1} and {9,y , 5,2}. If the medians of the two given datasets are equal, what is the value of ( y-x)^2?
Answer:
1Step-by-step explanation:
Median of a dataset is the value at the centre of the dataset after rearrangement.
Given the data {8,x , 4,1}, the median of the set will be two values(x and 4). Since we have two values as the median, we will take their average.
Median of the first data set = x+4/2 ...(1)
For the second dataset {9,y , 5,2}, the median will be y+5/2
Since we are told that the medians of both datasets are equal, we will equate the value of the medians of both datasets as given below;
x+4/2 = y+5/2
cross multiplying;
2(x+4) = 2(y+5)
Dividing both sides by 2 will give;
x+4 = y+5
From the resulting equation;
y-x = 4-5
y-x = -1
(y-x)² = (-1)² = 1

The area of the triangle, when a = 2 and c = 3, is 1512 square centimeters.
We must apply the formula for the area of a triangle, which is provided by: to determine the triangle's area.
(1/2) * Base * Height = Area
We can enter the values of a = 2 and c = 3 into the formula given that the base length is 3ac2 and the height is 2 centimetres greater than the base length.
Base length =\(3ac^2 = 3 * 2 * (3^2) = 3 * 2 * 9 = 54\) centimeters
Height is calculated as Base Length + 2 (54 + 2 = 56 centimetres).
Using these values as a substitute in the formula, we obtain:
Area =\((1/2) * 54 * 56 = 1512\) square centimeters

the probability of getting an even numbers out of this set is 1/2
Step-by-step explanation:
The set of numbers are: 10
1,2,3,4,5,6,7,8,9,10
Even Numbers: 5
2,4,6,8,10
Probability = \(\frac{NumberOfFavourableOutcomes}{TotalNumberOfOutcomes}\)
P = \(\frac{Even Numbers}{Total Numbers}\)
P = \(\frac{5}{10}\)
P = \(\frac{1}{2}\)
So, the probability of getting an even numbers out of this set is 1/2
Answer:
The probability of this set of numbers is 1/2.
Step-by-step explanation:
Probability is the odds of an event happening. It is expressed by writing it as a fraction, decimal, or a percent.
The formula for probability is the number of favorable outcomes divided by the total number of outcomes. In this case, we have odd and even numbers. The even numbers in this set are 2, 4, 6, 8, and 10.
These are the favorable outcomes.
Since there are 5 even numbers, there are 5 favorable outcomes.
There are total of 10 outcomes. Therefore P(Even number)= 5/10.
Don't forget to always simplify. You can divide the numerator and denominator by 5. 5 divided 5 is 1 and 10 divided by 5 is 2.
Therefore, the probability of choosing an even number from this set of numbers is 1/2.

Charlie the trainer has two solo workout plans that he offers his clients: Plan A and plan B. Each client does either one or the other (not both). On Wednesday there were 5 clients who did plan A and 6 who did plan B. On Thursday there were 3 clients who did plan A and 2 who did plan B. Charlie trained his Wednesday clients for a total of 7 hours and his Thursday clients for a total of 3 hours. How long does each of the workout plans last?
Plan A lasts for 0.5 hours, and Plan B lasts for 0.75 hours based on the given information and the solution to the System of equations.
To determine the duration of each workout plan, let's assume that both Plan A and Plan B have a fixed duration. Let's denote the duration of Plan A as "x" hours and the duration of Plan B as "y" hours.
From the given information, we can form the following equations:
On Wednesday:
5 clients did Plan A, so the total duration for Plan A is 5x hours.
6 clients did Plan B, so the total duration for Plan B is 6y hours.
The total training duration on Wednesday is 7 hours, so we have the equation: 5x + 6y = 7 ... Equation (1)
On Thursday:
3 clients did Plan A, so the total duration for Plan A is 3x hours.
2 clients did Plan B, so the total duration for Plan B is 2y hours.
The total training duration on Thursday is 3 hours, so we have the equation: 3x + 2y = 3 ... Equation (2)
We now have a system of equations (Equation 1 and Equation 2) that we can solve to find the values of x and y.
Multiplying Equation (1) by 2 and Equation (2) by 5 to eliminate the y variable, we get:
10x + 12y = 14 ... Equation (3)
15x + 10y = 15 ... Equation (4)
Multiplying Equation (3) by 3 and Equation (4) by 2 to create a new system of equations:
30x + 36y = 42 ... Equation (5)
30x + 20y = 30 ... Equation (6)
Subtracting Equation (6) from Equation (5), we can eliminate the x variable:
(30x + 36y) - (30x + 20y) = 42 - 30
16y = 12
y = 12/16
y = 0.75
Substituting the value of y into Equation (2), we can solve for x:
3x + 2(0.75) = 3
3x + 1.5 = 3
3x = 3 - 1.5
3x = 1.5
x = 1.5/3
x = 0.5
Therefore, the duration of Plan A is 0.5 hours, and the duration of Plan B is 0.75 hours.
Plan A lasts for 0.5 hours, and Plan B lasts for 0.75 hours based on the given information and the solution to the system of equations.

A rainstorm in Portland, Oregon, has wiped out the electricity in about 7% of the households in the city. A management team in Portland has a big meeting tomorrow, and all 6 members of the team are hard at work in their separate households, preparing their presentations. What is the probability that none of them has lost electricity in his/her household
Answer:
0.647 = 64.7% probability that none of them has lost electricity in his/her household
Step-by-step explanation:
For each household, there are only two possible outcomes. Either they lost electricity, or they did not. The probability of a household losing electricity is independent of any other household. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)
In which \(C_{n,x}\) is the number of different combinations of x objects from a set of n elements, given by the following formula.
\(C_{n,x} = \frac{n!}{x!(n-x)!}\)
And p is the probability of X happening.
A rainstorm in Portland, Oregon, has wiped out the electricity in about 7% of the households in the city.
This means that \(p = 0.07\)
6 members
This means that \(n = 6\)
What is the probability that none of them has lost electricity in his/her household?
This is P(X = 0). So
\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)
\(P(X = 0) = C_{6,0}.(0.07)^{0}.(0.93)^{6} = 0.647\)
0.647 = 64.7% probability that none of them has lost electricity in his/her household
En el cine, el precio de admisión de un niño es de 6 dólares y de un adulto es de 9,20 dólares . El sábado se vendieron 146 boletos de admisión para un total de ventas de 1135,20 dólares . ¿Cuántos boletos de admisión de niños se vendieron ese día?
Answer:
65 boletos.
Step-by-step explanation:
Antes de resolverSabemos que el precio para un niño es 6 dólares, y el precio para un adulto es 9,20 dólares. Además, el cine se vendió 146 boletos, y recibió 1135,20 dólares.
El procesoVamos a resolver este problema con un sistema, usando 2 varibles.
No sabemos cuantos boletos de niño el cine vendió, entonces el cine vendió <<x>> boletos de niños. Tampoco sabemos cuantos boletos de adultos vendió, entonces vendió <<y>> boletos de adultos.
En total, vendió 146 boletos; el número de los boletos de niños con el número de los boletos de adultos es 146 boletos.
Usando las variables, x + y = 146 boletos.
Esta es una de las equaciones que necesitamos.
Porque todos los boletos de niños es 6 dólares, si el cine vendió <<x>> boletos, su total de ventas (de boletos de niños) es <<6x>> dólares.
Lo mismo es verdad para los boletos de adultos; todos los boletos de adultos es 9,20 dólares, entonces si vendió <<y>> boletos, el total de ventas de boletos de adultos es <<9,20y>> dólares.
En total, las ventas de los boletos de niños + las ventas de los boletos de adultos es 1135,20 dólares.
O, con variables, es 6x + 9,20y = 1135,20
Nuestra sistema es:
x + y = 146
6x + 9,20y = 1135,20
Ahora necesitamos resolver esta sistema.
Podemos usar la sustitución. Vamos a resolver una de las eqaciones para una variable, y después, usar el valor de esa variable para encontrar la solución para una de las variables, y después, usar esa solución para encontrar la solución de la otra variable.
Podemos mover <<y>> al otro lado.
x + y = 146 => x = 146 - y
Ahora, podemos sustituir <<x>> para 146 - y en 6x + 9,20y = 1135,20
6(146-y) + 9,20y = 1135,20
Multiplica.
876 - 6y + 9,20y = 1135,20
Combina los términos que son los mismos.
876 + 3,20y = 1135,20
Mueva 876 al otro lado.
876 + 3,20y = 1135,20 => 3,20y = 259,20
Divide todo por 3,20.
3,20y/ 3,20 = 259,20/ 3,20
y = 81
Entonces, el cine vendió 81 boletos de adultos.
La respuestaRecuerda, esta (81 boletos de adultos) no es lo que necesitamos. Necesitamos cuantos boletos de niños vendió.
Entonces, podemos substituir <<y>> con 81 en x = 146 - y. Recuerda que <<x>> es cuantos boletos de niños vendió.
x = 146 - y => x = 146 - 81 => 65
Entonces, el cine vendió 65 boletos de niños.

Head lengths of brushtail possums follow a nearly normal distribution with mean 92.6 mm and standard deviation 3.6 mm.
a) What percent of possums have heads less than 95.4 mm?
b) What percent of possums have heads more than 85.8 mm?
c) What percent of possums have heads between 85.8 and 95.4 mm?
d) What is the maximum head length of the shortest 10% of possum heads?
a) Approximately 77.94% of possums have heads less than 95.4 mm.
b) Approximately 96.93% of possums have heads more than 85.8 mm.
c) Approximately 74.93% of possums have heads between 85.8 and 95.4 mm.
d) The maximum head length of the shortest 10% of possum heads is approximately 87.68 mm.
a) We can use the normal distribution to answer this question. Let X be the head length of a brushtail possum. Then X has a normal distribution with mean μ = 92.6 mm and standard deviation σ = 3.6 mm. We want to find P(X < 95.4 mm).
Using the standard normal distribution table or a calculator, we can find the z-score corresponding to a head length of 95.4 mm:
\(z = \frac{(95.4 - 92.6)}{3.6} = 0.78\)
Then, using the standard normal distribution table, we can find the probability that a standard normal variable is less than 0.78:
P(Z < 0.78) = 0.7794
Therefore, approximately 77.94% of possums have heads less than 95.4 mm.
b) Again, using the normal distribution with mean μ = 92.6 mm and standard deviation σ = 3.6 mm, we want to find P(X > 85.8 mm).
Finding the corresponding z-score:
\(z = \frac{(85.8 - 92.6)}{3.6} = -1.89\)
Using the standard normal distribution table, we find:
P(Z > -1.89) = P(Z < 1.89) = 0.9693
Therefore, approximately 96.93% of possums have heads more than 85.8 mm.
c) To find the percentage of possums with heads between 85.8 and 95.4 mm, we can subtract the probability of heads less than 85.8 mm from the probability of heads less than 95.4 mm:
P(85.8 < X < 95.4) = P(X < 95.4) - P(X < 85.8)
Using the same calculations as in parts (a) and (b), we get:
P(85.8 < X < 95.4) = 0.7794 - 0.0301 = 0.7493
Therefore, approximately 74.93% of possums have heads between 85.8 and 95.4 mm.
d) We want to find the maximum head length of the shortest 10% of possum heads. This is equivalent to finding the 10th percentile of the distribution. Using the normal distribution with mean μ = 92.6 mm and standard deviation σ = 3.6 mm, we want to find the head length x such that P(X < x) = 0.1.
Using the standard normal distribution table or a calculator, we can find the z-score corresponding to the 10th percentile:
P(Z < z) = 0.1
z = -1.28
Then, we can find the corresponding head length x:
x = μ + zσ = 92.6 + (-1.28)(3.6) = 87.68
Therefore, the maximum head length of the shortest 10% of possum heads is approximately 87.68 mm.

The similar shapes EFGH and JKLM have the measurement of angle Z equal to 65°, the length x = 27.5 and the length of y = 12
What are similar shapesSimilar shapes are two or more shapes that have the same shape, but different sizes. In other words, they have the same angles, but their sides are proportional to each other. When two shapes are similar, one can be obtained from the other by uniformly scaling (enlarging or reducing) the shape.
Given that the shape EFGH is a smaller shape of JKLM, and they are similar, then:
the measure of angle Z is equal to 65°
the side EF corresponds to JK and side FG corresponds to KL, so:
8/20 = 11/x
x = (11 × 20)/8 {cross multiplication}
x = 27.5
the side EF corresponds to JK and EH corresponds to JM, so:
8/20 = y/30
y = (30 × 8)/20 {cross multiplication}
y = 12
Therefore, the similar shapes EFGH and JKLM have the measurement of angle Z equal to 65°, the length x = 27.5 and the length of y = 12
