This histogram represents a sampling of recent visitors to the mall on a Friday night, grouped by their ages.

If you knew the exact values of the data points for this data set, which measure of center (the mean or median) would most likely provide a more accurate picture of the data set? Explain your reasoning.

the answer will be b x² +x-1

step-by-step explanation:

part a: 1.08

part b: 27.59

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.
