Answer: Honestly all the stuff we do in school will not be used in the real world
Step-by-step explanation: lowkey
Graph D, because no x-value repeats and it passes the vertical line test.
42 is 21% of 200. This is because 200*0.21 = 42.
PLUG in the numbers
4.5=500 x R x 2.5
divide both sides by 500
0.009=R x 2.5
divide 2.2 to both sides
R=.0036
In percent you have to multiply by 100 which is 0.36%
