Ms. Wilson surveyed her class of 36 students about their favorite ice cream flavors. • Two-thirds of the students preferred chocolate ice cream.
• One-fourth of the students preferred strawberry ice cream.
• The rest preferred vanilla ice cream.
How many students preferred vanilla ice cream?

1 student.

Step-by-step explanation:

Two thirds of the students preferred chocolate ice cream:

2/3 of 36 is 24 students.

One fourth of the students preferred strawberry ice cream:

1/4 of 36 is 9.

9+24= 35

36-35=1

Only one student preferred vanilla ice-cream.

1

Step-by-step explanation:

2/3 × 36

= 24 students preferred Choclate Ice cream

1/4 × 36

= 9 students prefer strawberry ice cream

total students who prefer Chocolate or Strawberry

9+24

=35

Remaining students

36-35

=1

only 1 student preferred vanilla ice cream

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
