Answer:
a. always
Step-by-step explanation:
In a simple linear regression, the slope measures the steepness of the linear relationship between the two variables, it ranges from (-∞ to +∞ ) while the correlation coefficient measures the tightness of the linear relationship between the two variables, it ranges from (-1 to +1 ).
So the correlation coefficient and the slope will always have the same sign though their values might differ.
So let's call the missing angles A, B, and C. We know that A + B + C = 180 and we also know that A = B and that C = A + B - 40. So our equation looks like this
180 = 4A - 40 and we add 40 on both sides of the equal sign and get
220 = 4A and we divide on both sides of the equal sign by 4 to get
55 = A So that means B = 55 as well. That means 55 + 55 = 110 and 110 - 40 = 70 So C = 70 and to check, 55 + 55 + 70 = 180.
The measures of the three angles are; 55 degrees, 55 degrees, and 70 degrees.
Answer:
Step-by-step explanation:
Angles formed when we turn clockwise in the given directions,
a) N to E → 90°
b). W to NE → (90° + 45°) = 135°
c). SE to NW → 180°
d). NE to N → 360° - 45° = 315°
e). W to NE → 90° + 45° = 135°
f). S to SW → 45°
g). S to SE → 360° - 45° = 315°
h). SE to SW → 180°
i). E to SW → 90° + 45° = 135°
X = x1+rx2/1+r ; y = y1+ry2/1+r donde r es la razón
aplicando la formula anterior las coordenadas serian x= -4/7 ; y=-11/7
donde x1 es la primera componente de punto A x2 la segunda componente del punto A y así mismo con Y<span />
