Answer: C. ±0.632.
Step-by-step explanation:
We have given,
Sample size : n= 10
Significance level : 
Test to check determine whether there is sufficient evidence to support a
claim of a linear correlation between two variables is a two tailed test.
Degree of freedom(df) = n- 2=8
Now , by the correlation coefficient(r) table ,
The critical r value corresponding to df = 8 and Significance level = 0.025 (0.05/2) is ±0.632.
Hence, the correct option is C. ±0.632.
Answer:
17.82
Step-by-step explanation:
since this is a right triangle you can use one of the trigonometric ratios, in this case it would be cosine because you have values for the adjacent and hypotenuse sides
cos(27°) = x/20
x = 20 · cos(27°)
x = 17.82
Answer:a=10
Step-by-step explanation:
I don’t know how to explain this in detail but I hope these notes and work help you.
En este problema simplemente tenemos que usar la suma de fracciones.
Veremos que entre ambos tienen un frasco entero de miel.
Sabemos que Clauida tiene 3/6 de un frasco de miel, y el hermano tiene 9/18 de un frasco de miel.
En total, entre ambos, tienen:
3/6 + 9/18
Para poder realizar esta suma tenemos que tener el mismo denominador en ambas fracciones, asi que podemos simplificar.
en 9/18 si dividimos numerador y denominador por 9 obtenemos:
9/18 = 1/2
en 3/6 si dividimos numerador y denominador por 3 obtenemos:
3/6 = 1/2
Así:
3/6 + 9/18 = 1/2 + 1/2 = 1
Entre ambos tienen un frasco entero de miel.
