The table contains the proof of the theorem of the relationship between slopes of parallel lines. what is the missing statement for step 62
slope of ac =
b, slope of ac = 15
°c slope of ac = - slope of dé
d. slope of ac = slope of dé
e slope of ac = 1 - slope of
slope of df

C

Step-by-step explanation:

Let the number of boys be b and the number of girls be g. We will make equations from the statements in the question.

Since the average weight of the boys is 60, the total weight of the boys is 60b , in likewise manner, the average weight of the girls is 48g

Using the arithmetic mean of both:

60b + 48g/(b + g) = 50

60b + 48g = 50b + 50g

60b -50b = 50g - 48g

10b = 2g

b/g = 2/10

b/g = 1/5
