The box plots below show student grades on the most recent exam compared to overall grades in the class:
two box plots shown. the top one is labeled class. minimum at 74, q1 at 78, median at 85, q3 at 93, maximum at 98. the bottom box plot is labeled exam. minimum at 81, q1 at 85, median at 93, q3 at 96, maximum at 99.

answer: i believe its b. if you sound out the sentences that sounds wrong.

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

step-by-step explanation:

hope it you

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
