A survey about the student government program at a school finds the following results:
190 students like the program
135 students think the program is unnecessary
220 students plan on running for student government next year.
If a circle graph were made from this data, what would the measure of the central angle be for the group that likes the program?
A message to Connections Academy teacher Ms. Vanchez from the Ohio district:
As you may have noticed, this seems like a place where cheating is encouraged. However, this is not the case. The teachers that built this website from the ground up established this place to become a website to help students in getting a better grade for their school work, not before they do it but after, so that they can learn from their mistakes and further improve their grade. Recently, people have been trying to trick the teachers here into getting the answers, and many have succeeded, but I want you to know this is not the main purpose of this website. It's okay to ban this website because of that, we all understand. We just wanted to let you know to not think of us as a bad website with a bad reputation. Talk to some of the officials like Ms. Sue, I'm sure she'll resolve the issue. :)
190/(190+135+220) * 360° = 125.5°
luckily i don't use a school computer hahahahahaha. Lol sorry.😜🤷♀️
Okay so i think i know how to do it now? idk if this is right but basically
I did cross-product (n/100 = 190/545)
545n = 19000
divide both sides by 545
that leaves us with a decimal (34.86238532)
The instructions say to round to the nearest whole number (35)
That's our percentage.
Next, take 35 and divide it by 100, which gives us 0.35
We multiply that by 360 (cause it's a circle graph, and circles are always 360 degrees) and we end up with 126(degrees)
that'll be your answer (hopefully? i mean, i'm not completely sure but this is my best guess honestly)
