The vertices of square cdef are c(1, 1), d(3, 1), e(3,−1) and f(1,−1). Which of the following shows that its diagonals are congr
maks197457 [2]

The equation -1 = -\frac {1}{1} shows that the diagonals are congruent perpendicular bisectors.

The vertices of the square are given as:

  • c = (1,1)
  • d = (3,1)
  • e =(3,-1)
  • f = (1,-1)

<h3>How to determine the congruent perpendicular bisectors.</h3>

Start by calculating the slope of diagonal ce using:

m = \frac{y_2 -y_1}{x_2  -x_1}

So, we have:

m = \frac{-1-1}{3  -1}

m = \frac{-2}{2}

m_1 = -1

Next, calculate the slope of diagonal df using:

m = \frac{y_2 -y_1}{x_2  -x_1}

So, we have:

m = \frac{-1-1}{1-3}

m = \frac{-2}{-2}

m_2 = 1

The slopes of both diagonals are:

m_1 = -1

m_2 = 1

By comparing both slopes, we have:

m_1 = -\frac {1}{m_2}

i.e.

-1 = -\frac {1}{1}

Hence, -1 = -\frac {1}{1} shows that the diagonals are congruent perpendicular bisectors.

QUESTION 17 - 1 POINT
Triss [41]

Answer:

PREGUNTA 17 - 1 PUNTO

Se sabe que leer un nombre en voz alta puede mejorar la memoria. A un psicólogo le gustaría probar la afirmación de que los adultos pueden

recordar más del 55 por ciento de los nombres de una lista, en promedio, después de leer la lista en voz alta. Para probar esta afirmación en el

nivel de significación, el psicólogo recopila los siguientes datos en una muestra de 50 participantes y registra el porcentaje de

nombres recordados en la lista después de leerla en voz alta. Los siguientes son los datos de este estudio:

Tamaño de la muestra = 50 participantes

Media de la muestra = 60 por ciento

A partir de datos anteriores, se sabe que la desviación estándar de la población es del 15 por ciento.

Trabaje con el procedimiento de prueba e interprete los resultados de la prueba de hipótesis. ¿Cuál es tu conclusión?

No se puede rechazar la hipótesis nula. NO hay pruebas sólidas para concluir que los adultos pueden recordar más

del 55 % de los nombres de una lista, en promedio, después de leer la lista en voz alta.

No se puede rechazar la hipótesis nula. Existe una fuerte evidencia para concluir que los adultos pueden recordar más que

los nombres en una lista, en promedio, después de leer la lista en voz alta.

Rechazar la hipótesis nula. NO hay evidencia sólida para concluir que los adultos pueden recordar más de 5

nombres en una lista, en promedio, después de leer la lista en voz alta.

Rechazar la hipótesis nula. Existe una fuerte evidencia para concluir que los adultos pueden recordar más del 55%

de los nombres en una lista, en promedio, después de leer la lista en voz alta.
