En el triángulo rectángulo ABC (B= 90°) se tiene que: Sen A = 1/3.Calcula sen C

ELEN [110]

Hi,

Podemos afirmar que en el triángulo rectángulo ABC el Sen(C) viene siendo 0.94 y el Sen(A) viene siendo 1/3.

Explicación:

Tenemos un triángulo rectángulo donde se cumple que sen(A) = 1/3, veamos cuánto vale este ángulo:

A = arcsen(1/3)

A = 19.47º

Ahora, si es un triángulo rectángulo significa que tiene un ángulo recto y además la suma de los ángulos internos debe ser igual a 180º, entonces:

A + B + C = 180º

19.47 + 90 + C = 180º

C = 70.53º

Finalmente:

Sen(70.53º) = 0.94

Por tanto, podemos afirmar que en el triángulo rectángulo el Sen(C) viene siendo 0.94.

One of the more famous anecdotes in the field of statistics is known as the "Lady Tasting Tea" and involves the renowned Not com

Brums [2.3K]

Answer:

c. between 0.01 and 0.001

Step-by-step explanation:

Given :

n = 40

x = 12

P = 0.5

H0: p = 0.50

Ha :p < 0.50

Sample proportion, p' = $\frac{x}{n} = \frac{12}{40} = 0.3$

This is a lower tailed test

Standard deviation will be:

$\sigma = \sqrt{\frac{P(1 - P)}{n}} = \sqrt{\frac{0.5(1 - 0.5)}{40}} = 0.0791$

For test statistic :

$= \frac{0.3 - 0.5}{0.0791} = -2.529 ≈ -2.53$

p-value wil be:

(P < Zobserved) = (P < -2.53)

From the normal distribution table,

NORMSDIST(-2.53) = 0.0057060 ≈ 0.0057

p-value = 0.0057

Therefore the p-value is between

c. between 0.01 and 0.001.
