The total length around the circle = 2 pi r = 2*pi*16 = 32 pi
Total degrees around the circle = 360 so
length of the arc of measure 270 = 32 pi * 270/360 = 24 pi units
or 75.40 units to the nearest hundredth
Answer:
The similarity ratio is 4 4/1 or 4
Step-by-step explanation:
You find that one of them has side lengths of 1 and the other has side lengths of 4
Answer:
0.4546
Step-by-step explanation:
nCr = n!/(n-r)!r!
Number of ways of selecting the four defective voltage regulators from 12 = 12C4 = 12!/(12-4)!4! = 12!/8!4! = (12 *11*10*9)/(4*3*2*1)
12C4 = 495 ways
Number of ways of selecting 2 defectives from line 1 = 6C2 * 6C2
6C2 = 6!/(6-2)!2! = 6!/4!2! = (6*5)/(2*1) = 15
6C2 * 6C2 = 15*15 = 225 ways
Probability = Number of possible outcomes/ Number of total outcomes
Probability that exactly 2 of the defective regulators came from line 1 = 225/40.95 = 0.4546
