An envelope is classified as a large envelope if the length exceeds 11.5 inches . What is the length of the envelope shown? Roun

Answer:

∠ R 90°

   

Explicación paso a paso:

Dado que en el triángulo RST

Ahora, según la condición, un ángulo es mayor que la suma de los otros dos ángulos.

En un triángulo, la suma de los tres ángulos es 180°

Por lo tanto, si un ángulo mide  90°, la suma de los otros dos debe ser igual a 90°

Y si uno de los ángulos es de 90°, solo los otros dos pueden ser de 45° cada uno.

Aquí suponiendo que el ángulo s = ángulo T = 30°, entonces con esta condición el ángulo r sería de 120°, que es mayor que 90°.

De lo anterior, se concluye que

Para,

∵ ∠ R = 120°, por lo tanto es mayor que 90°.

Es decir, ∠ R 90°

  Respuesta

In the case of an equilateral triangle ABC, each angle measures 60 degrees, as the total angle sum in any triangle is 180 degrees, and dividing that by 3 yields 60. Setting this equal to 3x-12, we have 60 = 3x - 12. After adding 12 to both sides, we get 72 = 3x, and dividing 72 by 3 gives us x = 24.66! I hope this clarifies things for you!

Answer:

Clarified below.

Detailed explanation:

A population refers to the entire group of data available for analysis, from which a smaller set is selected for closer scrutiny. This population can include individuals, articles, experiments, or measurements. Hence, a population represents a compilation of data pertaining to subjects that are linked by a shared feature.

A sample is a smaller, manageable portion derived from a larger group. It embodies the traits of a broader population. Samples are utilized in statistical tests when the overall population size is too vast to feasibly include all members in the analysis.

A parameter plays a significant role in statistical analysis. It refers to the attributes that characterize a specific population. Examples include population mean, population standard deviation, population proportion, etc.

When forming a statistical inference about the population being examined, the parameter value remains unknown because collecting data from every single individual in the population is unfeasible. Therefore, a sample is drawn from the population to draw conclusions about the parameter.

A statistic is the calculated value derived from this sample's characteristics. For instance, this includes sample mean, sample standard deviation, sample proportion, etc.

The matched pairs are represented as follows:

Population: 2. All Toyota Camry (2020 US) model vehicles.

Sample: 4. A selection of 117 Toyota Camry (2020 US) vehicles that were picked.

Parameter: 7. The mean mileage of all Toyota Camry (2020 US) model vehicles.

Statistics: 6. The city mileage averaged for the 117 sampled Toyota Camry (2020 US) cars, which is 27.8 mpg.

Response:

Dimensions of the rectangular fence:

x = 14 ft

w = 7 ft

A = 98 ft²

Detailed explanation:

Dimensions of the rectangular fence:

x = length, and w = width

Then x = 2*w ⇒ w = x/2

Perimeter is

p = 2*x + 2*w

p = 2*x + 2* x/2

p = 2*x + x

3*x = 42

x = 14 ft and w = 14/2  ⇒ w = 7 ft
