50 POINTS HELP DUE IN 30 MINS!!!

Mathematics
1 answer:
LUCKY_DIMON [66]3 years ago
3 0

9.

4 < 5 < 9

2^2 < 5 < 3^2

2 < \sqrt 5 < 3

-3 < -\sqrt 5 < -2 < -1.96312...

-\sqrt 5 < -1.96312...

10.

The least will be one of the negative ones, -3 or -6/5.  Since -6/5=-1.2, we see

-3 is the least

11.

81 < 90 < 100

9^2 < 90 < 10^2

9 < \sqrt{90} < 10

Answer: 10 feet

12.

We know \sqrt 8 > \sqrt 5 and 2.5 > 2 \frac 1 3

Since

2.5^2 = 6.25 < 8

\sqrt 8  is the tallest.

Are these triangles similar? explain why did you pick yes or no.
kupik [55]
No, their angles are not actually the same. The missing angle in the larger triangle is actually 31 rather than 41, although the picture is trying to trick you into thinking otherwise.

Qué medida de tendencia central (llamada a menudo promedio) es la más sensible a valores extremos?
docker41 [41]

Respuesta:

Significar

Explicación paso a paso:

Las medidas del centro incluyen la media, la mediana y la moda. La media se obtiene tomando la suma de los valores dividida por el número de valores individuales (frecuencia). La mediana es el percentil 50 de la distribución y la moda es el valor que ocurre con mayor frecuencia si se trata de una distribución. De todas las medidas, la media es la más afectada por la presencia.

Dados los datos:

2,4, 5, 2, 3, 3, 3, 5

La media = Σx / N = 2.3

Modo = 3

Mediana = 2, 2, 3, 3, 3, 4, 5, 5 = 1/2 * nth = 1/2 * 8 = 4to término = 3

Si se agrega un valor extremo: digamos 80

2, 2, 3, 3, 3, 4, 5, 5, 2, 80

Nueva media = Σx / N = 11,88

Mediana = 1/2 (n + 1) th término

Mediana = 1/2 (10) término = 3

Modo = 3

Podemos ver que la inclusión de 80, que es un valor extremo, cambia significativamente el valor medio.
