Answer:
No the lines are not perpendicular
Step-by-step explanation:
Slopes are not perpendicular reciprocals
Answer:
d
Step-by-step explanation:
A unit circle is the one which has radius equal to 1.
The relation between radius of circle (r), the arc length (s) and the radian measure of angle made by arc (Ф) is given as:
s = rФ
For a unit circle, r = 1, so the above equation becomes:
s= Ф
This means, the arc length will be equal to the angle made by that arc in radians.
Probability of finding no defective bulb
=95/100*94/99....86/91
=95!/(85!) / (100!/90!)
= 110983/190120
=>
Probability of finding at least one defective bulb
=1-110983/190120
= 79137/190120
= 0.41625 (to 5 decimal places)
