1 answer:
stellarik [79]3 years ago
6 0

Answer:

Answer is D. Mean decreases and median stays the same

Step-by-step explanation:

First put the amounts in this format

$31, $39, $50, $50, $70, $82

Median (middle of all numbers) is 50

Mean (add all numbers then divide by how many amounts there) is 53.6

Now incorporate the 7th week

$23, $31, $39, $50, $50, $70, $82

Median is still 50

Mean is now 49.28

Al sumar y/o restar números decimales, siempre se debe aplicar la norma de los signos. * 1 punto FALSO VERDADERO
Luden [163]

Answer:

La norma de los signos es para el producto de números reales, y la norma es la siguiente.

(+)*(+) = (+)

(+)*(-) = (-)

(-)*(+) = (-)

(-)*(-) = (+)

Es decir, el producto de dos números de mismo signo es siempre positivo

El producto de dos números de distinto signo es siempre negativo.

Particularmente, para la suma esta norma no funciona (pues no está definida para la suma)

Pero en casos como:

5 - (-4)  

(esto sería: "la diferencia entre cinco y menos cuatro")

notar que podemos reescribir esto como:

5 + (-1)*(-4)

Ahora podemos aplicar la norma de los signos:

5 + 4 = 9

Donde aplicamos la norma de los signos,  

Podemos concluir que, si bien es una regla que aplica al producto, siempre la tenemos que tener en cuenta en cualquier operación que hagamos.

Por lo podemos concluir que la respuesta correcta es verdadero.
