The director of a museum recorded the number of students and adult chaperones in several school groups visiting the museum. she organized
the data in a scatter plot, where x represents the number of students and y represents the number of adult chaperones. then she used a
graphing tool to find the equation of the line of best fit:
y = 0.123x + 5.397
based on the line of best fit, approximately how many students are predicted to be in a school group with 20 adult chaperones?

its 69.420

step-by-step explanation:

"exterior angles = 360 / number of sides.

60 = 360 / sides

sides = 360 / 60

sides = 6"

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
