A colored chip is yellow on one side and red on the other. The chip was flipped 50 times and landed on red side up 22 times. What is the relative frequency of the chip landing with the red side facing up?

36%

44%

52%

56%

42%

Step-by-step explanation:

You have essentially A fraction, 21/50, which gives you a decimal of 0.4 the 2, or 42%

44%

Step-by-step explanation:

Took the test and it was correct

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
