Answer:
135
Step-by-step explanation: any line has an angle of 180 degrees. Subtract 45 from 180 and you get your answer
Y = mx + n
m = Slope
To two lines be perpendicular to each other the slopes need to meet the condition: ma x mb = -1
y = 2x + 5
ma = 2
D: y = -1/2x + 5
mb = -1/2
ma x mb = -1
2 x -1/2 = -1
2/1 x -1/2 = -1
-2/2 = -1
-1 = -1
It's true.
Answer: D.
I’m guessing that the 5th percentile is app. 2 standard deviations which I think is right. In that case the 5th percentile will tend to wait for 212+2(24.7)= 261.4 (days?). Hope that helps!
7 to 12 is actually already in the simplest form.
