The answer is C. m∠1 + m∠4 = 180°
Answer:
Below
Step-by-step explanation:
Well I can't really see the equation but I can tell you how to do it.
Parallel slopes are the same slope as the equation.
For example, y = mx + b
The slope of a line parallel to it is m
Perpendicular slopes are the opposite reciprocal as the equation.
For example, y = mx + b
The slope of a line perpendicular to it is
Answer:
Un excursionista camina por un prado llano, observando una montaña a
lo lejos. Mide que el ángulo de elevación entre el suelo
y la cima de la montaña es de 25 grados. Camina 5 millas y luego
mide el ángulo de elevación nuevamente, ahora es de 40 grados. ¿Qué altura tiene
la montaña?

Answer: A.) Critical values: r= ± 0.514, no significant linear correlation
Step-by-step explanation:
r = 0.105
n = 15
The level of significance for a two-tailed test is 0.05
The degrees of freedom = n - 2 = 15 - 2 = 13
Using the pearson product moment correlation Coefficient table ; The critical value for the correlation Coefficient is ±0.513977
When the correlation coefficient (for a sample of 15 drawn from the same population) is less than ±0.514 (critical value), that means no significant linear correlation exists.
