At Brighton Middle School, Mr. Yule asked 50 randomly selected students from each grade level about their favorite subject, and

12 chose science. He used this data to draw the inference that about 25% of middle school students will indicate science is their favorite subject. If there are 200 students all together, did he make a reasonable inference?

Original price is $29.99 markdown 33 1/3%
nikklg [1K]

The <em><u>correct answer</u></em> is:

$19.99.

Explanation:

33 1/3% is equal to taking 1/3 of a number. To take 1/3 of a number, we multiply by 1/3:

29.99(1/3) = 29.99/3 = 9.9966666667 ≈ $10

This means the price is marked down by $10. This makes the new price 29.99-10 = 19.99

Durante un frente frío, la temperatura Canadá bajó de 7°C a -5°C ¿Cuántos grados bajo la temperatura
Anton [14]

Answer:

Durante el frente frío mencionado en el ejercicio, la temperatura de Canadá bajó:

  • <u>12°C</u>.

Step-by-step explanation:

Para obtener la cantidad de grados que bajó la temperatura en el caso mencionado, debes primero identificar la disminución en los grados positivos, es decir, cuando los grados Celsius llegaron a 0°C:

  • Diferencia entre 7°C y 0°C = <u>7°C</u>

En la operación matemática, solo restante la cantidad de grados necesarios a la temperatura inicial (7°C) para que la temperatura quedara en 0°C, donde obtenemos una diferencia de 7°C, ahora identificas la cantidad de grados que se necesitan para que la temperatura pase de 0°C a -5°C:

  • Diferencia entre 0°C y -5°C = <u>5°C</u>

Recuerda que como ya estamos hablando de diferencia, no necesitas señalar si los grados son negativos, solo identificamos el número de grados Celsius entre esas temperaturas mencionadas, por lo tanto, al final sumas las dos diferencias halladas y esa será la diferencia total entre las dos temperaturas dadas:

  • Diferencia entre 7°C y -5°C = 7°C + 5°C
  • <u>Diferencia entre 7°C y -5°C = 12°C</u>

Por lo tanto, durante el frente frío mencionado, <em><u>la temperatura en Canadá bajó 12°C</u></em>.
