How many degrees are in the "Thriller" sector of the graph? Round your answer to the nearest degree. picture in comments (:
ok, how many degrees are there in total?
125 in that graph
That's, not quite right. Think of it this way, if you turn around in a circle (any circle!), how many degrees have your turned?
360
That's right, the amount of degree's in any circle if you start from the center and go around is always 360. Now, it's a rule of pie graph's that degree's in each sector is proportionate to the sector's size vs. the total amount of data. ie. the ratio of amount in the one section vs. amounts in all sections is equivalent to degrees in one section to 360 degrees. So your next step is to figure out how many movies are in that one section vs. in all sections
16 to 125 ?
yes, now make an equation, on the one side, put 16 over 125, on the other side, put x over 360, where x is the number of degrees that Thillers take up, solve for x.
so 46.08 or 46 is the answer (:
yes, do you understand where the formula came from?
nope .
