The mean weight of 25 student in a class is 58kg. The mean weight of a class of 29 students is 62kg. Find the mean weight of all the students

weight of 25 students

25 × 58 = 1450kg

weight of 29 students

29 × 62 = 1798kg

total students = 25 + 29 = 54

total weight of students = 1450 + 1798 = 3248

mean weight of all students = 3248/54 = 60.19kg

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

the equation of the line that passes through the points and has o form

if line passes through the points (-1, -3) and (2, 1), then

the equation in the standard form is
