Find the values of variables and the measures of the indicated angles.

A. IQR or B. IQR is the correct response since Sunny Town is symmetrical or Sunny Town is asymmetrical.

The pattern of data distribution across various values or intervals is referred to as a distribution. The form, centre, and dispersion of a set of data can be described and examined in this manner.

We need to measure the fluctuation of the temperature data in both locations in order to decide which place has the most stable temperature. The interquartile range (IQR), which quantifies the spread of the middle 50% of the data, is the ideal measure of variability for this application.

As a result, depending on how the distributions are shaped, the answer is either A. IQR because Sunny Town is symmetric or B. IQR because Sunny Town is skewed. The IQR would be a suitable tool to gauge the data's spread if Sunny Town's temperature data were symmetric. The IQR would also be useful to measure the spread of the data if Sunny Town's temperature data were skewed. Therefore, the range would not be a suitable indicator of variability if the temperature data from either location were not skewed.

Answer: 56

Step-by-step explanation:

66 x 2 = 132

132-76 = 56

(76+52) divided by 2 = 66

Hence the mean score for class B is 56.

It would  take 5 people to paint the same wall is 1 hour and 20 minutes or 1:20.

It is clear that workers twice as fast as people when painting the same surface. This means that John will always draw twice as much area as people at any given time if they are working at the same time. So if they plan well and finish painting the room at the same time, John will paint twice as much area as people.

There is only one possibility:

3 people = 4 hours

Divide by 3.

1 person = 4/3 or 1 1/3 hours

There are 60 minutes in 1 hour. Multiply 1/3 by 60.

(1/3)× 60 = 60/3 = 20

1/3 of an hour is 20 minutes.

Untuk menyelesaikan masalah ini, kita perlu menyelesaikan sistem persamaan linear dua variabel pertama dan sistem persamaan linear tiga variabel:

Sistem Persamaan Linear Dua Variabel:

2x + 3y = 8 ... (1)

-4x + 6y = 8 ... (2)

Untuk menyelesaikan sistem persamaan ini, kita dapat menggunakan metode eliminasi:

Langkah 1: Kalikan Persamaan (1) dengan 2 dan Persamaan (2) dengan 1. Kita memperoleh:

4x + 6y = 16 ... (3)

-4x + 6y = 8 ... (4)

Langkah 2: Tambahkan Persamaan (3) dan Persamaan (4). Kita memperoleh:

12y = 24

Langkah 3: Bagi kedua sisi dengan 12. Kita memperoleh:

y = 2

Langkah 4: Substitusikan y = 2 ke dalam Persamaan (1) atau (2). Kita memperoleh:

2x + 3(2) = 8

2x + 6 = 8

2x = 2

x = 1

Jadi, solusi dari sistem persamaan linear dua variabel adalah (x, y) = (1, 2).

Sistem Persamaan Linear Tiga Variabel:

x - z = -4 ... (5)

x + y + z = ?

2x + 3y = 8

Untuk menyelesaikan sistem persamaan ini, kita dapat menggunakan metode substitusi:

Langkah 1: Substitusikan x = 1 dan y = 2 dari sistem persamaan linear dua variabel ke dalam Persamaan (3). Kita memperoleh:

2(1) + 3(2) = 8

2 + 6 = 8

8 = 8

Langkah 2: Substitusikan x = 1 dari sistem persamaan linear dua variabel ke dalam Persamaan (5). Kita memperoleh:

1 - z = -4

z = 5

Langkah 3: Substitusikan x = 1 dan z = 5 ke dalam Persamaan (6). Kita memperoleh:

1 + y + 5 = ?

y = -6

Jadi, solusi dari sistem persamaan linear tiga variabel adalah (x, y, z) = (1, -6, 5).

Maka nilai x + y + z adalah:

x + y + z = 1 + (-6) + 5 = 0

Jadi, nilai x + y + z adalah 0

The total monthly PITI of the mortgage loan, given the principal and the tax, would be $ 2, 512.08.

To find the monthly PITI, you first need to find the principal and interest portion by the formula :

= Amount financed / 1, 000 x factor for 8.75%, 15 years

= 188, 000 / 1, 000 x 10

= $ 1, 880

The monthly tax and insurance portion would be:

= ( Estimated property tax + Annual insurance ) / 12

= ( 5, 475 + 2, 110 ) / 12

The probability that a random sample of 55 students has a mean age of less than 19.2 age years is 0.3866 and the probability that a random sample of 55 students has a mean age between 18.8 and 23 years is 0.27808.

a. To find P(x < 19.2), we need to find the area under the normal distribution curve to the left of x = 19.2. We can use the formula for z-score to standardize the value of x:

z = (x - μ) / δ = (19.2 - 20.9) / 5.9 = -0.2881

Looking up the area to the left of z = -0.2881 in a standard normal distribution table or using a calculator, we find that the probability is approximately 0.3869. So P(x < 19.2) is 0.3866.

b. To find P(18.8 < x < 23.0), we need to find the area under the normal distribution curve between x = 18.8 and x = 23.0. Again, we can standardize the values of x and use a standard normal distribution table or calculator:

z1 = (18.8 - 20.9) / 5.9 = -0.3559

z2 = (23.0 - 20.9) / 5.9 = 0.3559

Looking up the area between z1 = -0.3559 and z2 = 0.3559 in a standard normal distribution table or using a calculator, we find that the probability is approximately0.27808. So P(18.8 < x < 23.0) is 0.27808.

According to the trigonometric functions, the answer is A. StartFraction 12 Over 13 EndFraction.

What are trigonometric functions?

Trigonometric functions are mathematical functions that relate the angles of a right triangle to the ratios of its sides. There are six primary trigonometric functions:

Sine (sin): the ratio of the opposite side to the hypotenuse of a right triangle.

Cosine (cos): the ratio of the adjacent side to the hypotenuse of a right triangle.

Tangent (tan): the ratio of the opposite side to the adjacent side of a right triangle.

Cosecant (csc): the reciprocal of the sine function, i.e. the ratio of the hypotenuse to the opposite side of a right triangle.

Secant (sec): the reciprocal of the cosine function, i.e. the ratio of the hypotenuse to the adjacent side of a right triangle.

Cotangent (cot): the reciprocal of the tangent function, i.e. the ratio of the adjacent side to the opposite side of a right triangle.

To find sin(K), we need to use the definition of sine which is the opposite side over the hypotenuse:

sin(K) = opposite / hypotenuse

In this case, the opposite side is LM and the hypotenuse is KM. We are given that KM = 13 and LM = 12, so we can plug these values into the formula:

sin(K) = 12/13

Answer: 18d

Step-by-step explanation:

To find the greatest common factor (GCF) of the terms in the polynomial 18d^4e^2 − 45d^2 + 36d, we need to factor each term into its prime factors and then identify the common factors with the highest exponent for each variable.

The prime factors of each term are:

18d^4e^2 = 2 x 3^2 x d^4 x e^2

45d^2 = 3^2 x 5 x d^2

36d = 2^2 x 3^2 x d

To find the common factors, we need to look for factors that appear in all terms. The common factors with the highest exponent for each variable are:

2^1, 3^2, and d^1.

Therefore, the GCF of the terms in the polynomial is:

2 x 3^2 x d = 18d

Hence, the GCF of the terms in the polynomial 18d^4e^2 − 45d^2 + 36d is 18d.

Erin will need to purchase 48ft² of tile for her kitchen island.

In order to calculate the square footage of tile needed for Erin’s kitchen island, we will use the formula for the area of a rectangle: A = lw, where A is the area, l is the length, and w is the width.

The first step is to measure the length and width of the island. Let’s assume that the length is 16ft and the width is 3ft.

Next, we will use the formula to calculate the area of the island: A = lw

A = 16ft x 3ft

A = 48ft²

Finally, Erin will need to purchase 48ft² of tile for her kitchen island.

To double check our calculations, we can also calculate the area of each individual side of the island. For example, the area of the 16ft side is 16ft x 2ft = 32ft². The area of the 3ft side is 3ft x 7ft = 21 ft². When we add the areas together, 32ft² + 21ft² = 53ft². Since 53ft² is greater than 48ft², it is clear that calculating the area of the entire island is the correct solution.

The process of figuring out the unknown variables while keeping the equations balanced on both sides is known as the system of equations method. We solve an equation system by identifying the value of the variable that makes the condition of all the provided equations true. There are numerous methods for solving a system of equations.

Multiply the equation 4x+2y=23.50 by 2.

From the other equation, subtract.

Calculate y using a solution.

To find the value of x, substitute the value for y into one of the equations.

To eliminate one variable (either x or y) while utilising the elimination method, the equations are added or subtracted.

To start, we can multiply the first equation by 2 to get rid of the 2y term:

8x + 4y = 47

Next, we can subtract the second equation from this equation to eliminate the 8x term:

2y = 10

y = 5

Now that we have solved for y, we can substitute this value into one of the original equations (let's use the first one) to solve for x:
