A set of college student heights are normally distributed with a mean of 170.4 centimeters and a standard deviation of 10 centimeters. What proportion of student heights are between 145 centimeters and 171 centimeters? You may round your answer to four decimal places.

0.550127

Step-by-step explanation:

Prob ( 145 < x < 171) =

Prob (  (145 - 170.4)/10 < z < (171-170.4)/10 ) =

Prob ( -2.54 < z < 0.14) =

Prob ( z < 0.14) - Prob (  z< -2.54) =

0.550127

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
