Answer:
angle of depression = -12 degrees
Step-by-step explanation:
Sin = opposite/hypotenuse
sin = -208/1000
inv sin 0.208 = -12
number of MP3 players: 4500 based on information given, 2 out of 50 MP3 players are defective. this means every 50 samples, 2 would be defective 4500/50 = 90 90 • 2 = 180 so, your final answer would be: 180 MP3 players in the shipment are likely to be defective
Answer:
D
Step-by-step explanation:
1. a)CK²=CH²+HK², CH - radius
CH²=CK²-HK²=50²-30²=2500-900=1600 ft²
CH=40 ft -- radius
b) cos(KCH)= CH/CK=40/50=4/5
KCH=arccos(4/5)≈36.87°
2)C=2πr≈2*3.14*40=251.2 ft
C=2*40π=80π ft --- exact
3) A =πr²=40²π=1600π ----exact
A≈1600*3.14=5024 ft
