The ages of the people in attendance at the showing of an award-winning foreign film are shown below. A graph shows age of attendees (in years) labeled 0 to 20 thru 61 to 80 on the horizontal axis and frequency on the vertical axis. 0 to 20 years at frequency 15. 20 to 40 years at frequency 40. 41 to 60 years at frequency 40. 61 to 80 years at frequency 15.
Which statement must be true according to the histogram?

The data is symmetrical, showing that the majority of the attendees were between the ages of 30 and 50.
The data is symmetrical, showing that the majority of the attendees were between the ages of 21 and 60.
The data is skewed, showing that the majority of the attendees were between the ages of 30 and 50.
The data is skewed, showing that the majority of the attendees were between the ages of 21 and 60

i think it would be 42cm

could u provide us some answer choices or hmm idk maybe a table for us to anser with ? ?

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
