In a certain elementary school, 52% of the students are girls. A sample of 65 students is drawn. 1) What is the probability that less 60% of them are girls.

A) 0.0018

B) 0.8023

C) 0.8773

D) 0.9016

Type A, B, C, or D in the box

2) What is the probability that more than 70% of them to be girls.

A) 0.0018

B) 0.8023

C) 0.8773

D) 0.9016

Type A, B, C, or D in the box

3) Would it be unusual for more than 70% of them to be girls.

Type "usual" or "unusual" in the box

square pyramid

step-by-step explanation:

square prism looks like nothing like that

triangular prism has a rectangular base instead of a square base

tetrahedron has a triangular base

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

answer: it's d

step-by-step explanation:

i believe that the answer is

b. y-1=-2(x-4)

hope this !
