Answer:
perpendicular
Step-by-step explanation:
The lines are not parallel because the slopes are not equal. However, they are perpendicular because perpendicular lines' slopes are opposite reciprocal. (×negative with the denominator and numerator switched.)
80 - 64 = 16
16 ÷ 80= 0.2
0.2= 20%
I don't know.. what happens next?
Solution :
Alpha, α = 0.01
The sample proportion is :
= 0.636
Test statistics,
z = 7.727
The p value = 0.00001
Here we observe that p value is less than α, and so we reject the hypothesis .
Therefore, there is sufficient evidence,
(0, 2 )
to find the y-intercept, let x = 0 in the equation
x = 0 , then 10y = 20 ⇒ y = 2 ← ( y- intercept ) ⇔ (0, 2 )
