Answer:

Its A

Step-by-step explanation:

area of triangle + area of rectangle

1/2 * base * height + length * breadth

1/2 * 24 * 4 + 24 * 8

48 + 192

240

Answer:

240

Step-by-step explanation:

For the square, we multiply 8 * 24 and we get 192

The triangle, we first know the length overall for both the square and triangle is 12, but its cut off, so we subtract 12 from 8 because that is the lenght for the square and we get 4. However, remember that this is a triangle, so we divide 4 by 2, we get 2. Multiply 2 from the width fo the triangle which is 24 and we get 48. Sum it all up 192 + 48 and we get 240.

The error in the distance if the uppermost portion of a 3. 0m long stadia rod is inclined 14 cm toward the observer and the rod intercept is 1. 75m on a horizontal sight is 8.167cm.

The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. it is given as,

Tan(θ) = Perpendicular/Base

where,

θ is the angle,

Perpendicular is the side of the triangle opposite to the angle θ,

The base is the adjacent smaller side of the angle θ.

Given the uppermost portion of a that is 3.0m long stadia rod is inclined 14 cm toward the observer, therefore, the angle of inclination, θ can be written as

tan(θ)=0.14/3

θ = 2.672°

Also, the rod intercept is 1.75m, therefore, t the error in distance in the distance is,

tanθ=x/1.75

x = 1.75 tan(θ)

x = 1.75 × tan(2.672°)

x = 0.08167 m = 8.167 cm

Hence, the error in the distance if the uppermost portion of a 3. 0m long stadia rod is inclined 14 cm toward the observer and the rod intercept is 1. 75m on a horizontal sight is 8.167cm.

The length of each leg in the 45-45-90 triangle is 27.

In a 45-45-90 triangle, the two legs are congruent, which means they have the same length. Let's call the length of each leg "x".

According to the Pythagorean theorem, in any right triangle, the sum of the squares of the legs is equal to the square of the hypotenuse. In this case, we can write:

\(x^2 + x^2 = (2\sqrt14)^2\)

Simplifying the right side, we get:

\(2x^2 = 4(14)\)

\(2x^2 = 56\)

Dividing both sides by 2, we get:

\(x^2 = 28\)

Taking the square root of both sides, we get:

x = ±√28

We can simplify √28 by factoring it into √4 and √7, since 4 is a perfect square:

x = ±√(4*7)

x = ±(2√7)

Since x represents the length of a side of a triangle, it cannot be negative, so we take the positive value:

x = 2√7

Therefore, each leg of the 45-45-90 triangle is 2√7.

The residual if you know the actual number is 3 and the predicted value is 1.6l is 1.4.

The residual is a measure of the difference between the predicted value and the actual value. In this case, the actual number is 3, and the predicted value is 1.6. To find the residual, we subtract the predicted value from the actual value:

Residual = Actual Value - Predicted Value

= 3 - 1.6

= 1.4

Therefore, the residual in this case is 1.4.

The residual represents the error or the amount by which the predicted value differs from the actual value.

A positive residual indicates that the predicted value is lower than the actual value, while a negative residual indicates that the predicted value is higher than the actual value.

In this case, the positive residual of 1.4 indicates that the predicted value of 1.6 underestimates the actual value of 3 by 1.4.

Answer:

Step-by-step explanation:

The probability that the die chosen is the fair die given the observed rolls is approximately 0.001032 or about 0.1032%.

We have,

To find the probability that the die you chose is the fair die given the sequence of rolls (4, 3, 6, 6, 5, 5), we can use Bayes' theorem.

Let's denote the event of choosing the fair die as F and the event of choosing the biased die as B. We want to find P(F | 4, 3, 6, 6, 5, 5), which represents the probability of choosing the fair die given the observed rolls.

According to Bayes' theorem, the probability can be calculated as:

P(F | 4, 3, 6, 6, 5, 5) = P(F) x P(4, 3, 6, 6, 5, 5 | F) / P(4, 3, 6, 6, 5, 5)

The individual probabilities in the equation can be calculated as follows:

P(F) = 0.5 (since the dice are chosen randomly)

P(4, 3, 6, 6, 5, 5 | F) = P(4 | F) x P(3 | F) x P(6 | F) x P(6 | F) x P(5 | F) x P(5 | F)

= (1/6) x (1/6) x (1/6) x (1/6) x (1/6) x (1/6)

= 1 / 46656

P(4, 3, 6, 6, 5, 5) = P(F) x P(4, 3, 6, 6, 5, 5 | F) + P(B) x P(4, 3, 6, 6, 5, 5 | B)

= P(F) x P(4, 3, 6, 6, 5, 5 | F) + P(B) x P(4, 3, 6, 6, 5, 5 | B)

= P(F) x P(4, 3, 6, 6, 5, 5 | F) + P(B) x P(4 | B) x P(3 | B) x P(6 | B) x P(6 | B) x P(5 | B) x P(5 | B)

= (1/2) x (1/46656) + (1/2) x (0.15) x (0.15) x (0.25) x (0.25) x (0.15) x (0.15)

Finally, we can substitute the values into the equation to find the probability:

P(F | 4, 3, 6, 6, 5, 5) = (0.5 x (1/46656)) / ((1/2) x (1/46656) + (1/2) x (0.15) x (0.15) x (0.25) x (0.25) x (0.15) x (0.15))

After performing the calculations, the probability that the die you chose is the fair die given the observed rolls is approximately 0.001032 or about 0.1032%.

Thus,

The probability that 2 or more new members will enroll during a given month is approximately 0.99698084.

To calculate the probability that 2 or more new members will enroll during a given month, we can use the complement rule.

The mean number of new membership enrollments in a month is given as λ = 8. The Poisson probability distribution can be defined as P(x; λ) = (e^(-λ) * λ^x) / x!, where x is the number of events.

To find the probability that 2 or more new members will enroll, we need to find the complement of the probability that fewer than 2 members will enroll.

Let's calculate the probability of 0 or 1 new members enrolling first:

P(0 or 1) = P(0) + P(1)

Using the Poisson probability formula:

P(0) = (e⁻⁸ * 8⁰) / 0! = (e⁻⁸ * 1) / 1 = e⁻⁸

P(1) = (e⁻⁸ * 8^1) / 1! = (e⁻⁸ * 8) / 1 = 8e⁻⁸

P(0 or 1) = e⁻⁸ + 8e⁻⁸

Now, we can calculate the probability that 2 or more new members will enroll:

P(2 or more) = 1 - P(0 or 1)

P(2 or more) = 1 - (e⁻⁸ + 8e⁻⁸)

P(2 or more) ≈ 1 - (0.00033546 + 0.0026837) ≈ 1 - 0.00301916 ≈ 0.99698084

Therefore, the probability that 2 or more new members will enroll during a given month is approximately 0.99698084.

we can conclude that the angle at which the boat will approach the opposite bank is 90 degrees.

We cannot see the given path in the question, but the angle of approach can be explained.

A boat is travelling from one side of a river to the other side, and we have to determine the angle at which the boat approaches the opposite bank. In the provided problem, it is not mentioned that how far did the boat travel? So we will take an average angle from both the banks which is a right angle or 90 degrees.

Therefore, the measure of angle at which the boat will approach the opposite bank is 90 degrees, or a right angle.

In the given question, we need to find the angle at which the boat will approach the opposite bank, while taking a trip across the river. But, the exact distance that the boat travelled across the river is not given. We assume that the average angle from both the banks is a right angle, which is 90 degrees.

So, the angle at which the boat will approach the opposite bank will be 90 degrees. This is because the boat should be perpendicular to the bank to avoid crashing into the bank, as the angle of incidence equals the angle of reflection. So, the correct option is 90 degrees.

Using Gaussian elimination method, find the solution to the given system of equations as follows: {bmatrix}1 & -2 & 6  -2 & 1 & 6  -1 & 2 & 6  2 & -1 & 6 {bmatrix} Now we perform some row operations:

R2 → R2 + 2R1R3 → R3 + R1R4 → R4 - 2R1

{bmatrix}1 & -2 & 6  0 & -3 & 18  0 & 0 & 12  0 & 3 & -6 {bmatrix} Now, we get y as: -3y = 18 y = -6 Next, we use this value to find x as follows: x - 12 = 4, x = 16 Thus, the solution to the given linear system of equations is x=16 and y=-6. In the given problem, we are given a linear system of equations with 2 equations and 2 variables. In order to solve these equations, we use Gaussian elimination method which involves using elementary row operations to transform the system into a form where the solutions are easy to obtain.To use the Gaussian elimination method, we first form an augmented matrix consisting of the coefficients of the variables and the constant terms. Then, we perform row operations on the augmented matrix to transform it into a form where the solution can be obtained directly from the last column of the matrix. In this case, we have four equations and two variables. Hence we will form a matrix of 4x3 which consists of the coefficients of the variables and the constant terms.The first step is to perform elementary row operations to get the matrix into a form where the coefficients of the first variable in each equation except for the first equation are zero. We can do this by adding multiples of the first equation to the other equations to eliminate the first variable.Next, we perform elementary row operations to get the matrix into a form where the coefficients of the second variable in each equation except for the second equation are zero. We can do this by adding multiples of the second equation to the other equations to eliminate the second variable.Finally, we use back substitution to solve for the variables. We start with the last equation and solve for the last variable. Then we substitute this value into the second to last equation and solve for the second to last variable. We continue this process until we have solved for all the variables.In this problem, we performed the Gaussian elimination method and found that the value of x is 16 and the value of y is -6. Hence the solution to the given linear system of equations is x=16 and y=-6.

Thus, we can conclude that Gaussian elimination method is a very efficient way of solving the linear system of equations. By transforming the system into a form where the solution can be obtained directly from the last column of the matrix, we can obtain the solution in a very short time.

Find the value of x for the below figure.

Answer:  15x + 25y = 4500

Step-by-step explanation:

The cost per general admission tickets is $15  and if x is used to represent the number of general admission tickets then 15 has to be multiplied by  x  and that gives the expression   15x  

The same with the VIP tickets, each one cost $25 and y is used to represent the number of VIP tickets sold, so if you want to find out how much a number of VIP tickets cost then you will have to multiply 25 by y  and that derives the expression  25y.

A combination of both tickets has to equal $4500 because that is amount they were both sold to get in total.

15x + 25y = 4500

The case fatality rate is 400 * 100 / 1500 = 26.67 (option d).

For the first scenario, the data determine that there is a difference in average expenditure between the two countries (option c). The P-value of 0.063 suggests that there is a moderate level of statistical significance, indicating that the difference in average expenditure is likely not due to random chance.

In the second scenario, the fact that the 95% confidence interval for the average number of times participants saw their provider per year (3.3) ranges from 0.1 to 6.1 is of statistical use because it provides a range estimate within which the true population means is likely to fall. This interval helps account for the uncertainty associated with the sample estimate and provides a measure of the precision of the estimate (option a).

For the third scenario, the average operating margin is appropriate to use because it is a measure of central tendency that represents the typical financial performance of rural hospitals. The standard deviation provides information about the variability of the operating margins (option d).

In the fourth scenario, the consideration factor that will ultimately contribute to the spread of Ebola is the population density of the affected area (option b). While factors like the influence of non-indigenous people and climatic conditions may play a role, population density is a key determinant in the transmission and spread of infectious diseases.

For the fifth scenario, the case fatality rate is calculated by dividing the number of deaths from the disease (400) by the total reported cases (1500) and multiplying by 100. Therefore, the correct calculation is 400 * 100 / 1500 = 26.67 (option d). This indicates that the case fatality rate is approximately 26.67%.

Answer:

\( \boxed{ \bold{ \huge{ \boxed{ \sf{(x + 4)}}}}}\)

Step-by-step explanation:

\( \sf{ {x}^{2} - 5x - 36}\)

Find the two numbers that multiplies to 36 and subtracts to 5

\( \dashrightarrow{ \sf{ {x}^{2} - (9 - 4)x - 36}}\)

Distribute ( - ) sign through the parentheses

\( \dashrightarrow{ \sf{ {x}^{2} - 9x + 4x - 36}}\)

Take x as common

\( \dashrightarrow{ \sf{x(x - 9) + 4x - 36}}\)

Take 4 as common

\( \dashrightarrow{ \sf{x(x - 9) + 4(x - 9)}}\)

\( \dashrightarrow{ \sf{(x - 9)(x + 4)}}\)

( x + 4 ) is the other factor of x² - 5x - 36
