Answer:
A
Step-by-step explanation:
Both vectors have the same length/ magnitude, so they are equal and since they are going the same direction, they're also parallel and won't touch.
(Just took the quiz btw)
0.8x + 2.71 = 1.898 - 0.6x
Add 0.6x to each side.
0.6x + 0.8x + 2.71 = 1.898 - 0.6x + 0.6x
1.4x + 2.71 = 1.898
Subtract 2.71 from both sides.
-2.71 + 1.4x + 2.71 = 1.898 - 2.71
1.4x = -0.812
____=_____
1.4 = 1.4
Divide by 1.4
x = -0.58
Hope I helped
Answer:
Step-by-step explanation:
The sample proportion 
The null hypothesis and the alternative hypothesis:
Thus; the test statistics is:
P-value = 2 × P(Z< - 1.768)
From the z tables
P-value = 2 × 0.03853
P-value = 0.07706
Thus, the p-value is 0.05 < P-value < 0.10
Answer:
C). Supplementary.
Step-by-step explanation:
We know this because with the sum of the angles a straight line (180 degree angle) is created.
