I believe the answer would actually be A) 0.239 because you would add up all the data from each section (So 32+20+25+30+18+15+58+45) and you get 243. Then you can set up the proportion 58/243 (since there are 58 juniors taking Spanish) and when you divide 58 by 243. you get the decimal 0.23868.... which rounds up to 0.239. Hope this helps!
Answer:
Answer is A.
Step-by-step explanation:
I'm pretty sure lmk if I'm wrong.
0=4(x²+8x+16)-12
0=4x²+32x+64-12
0=4x²+32x+52
0=x²+8x+13
D=b²-4ac
D=64-52=12
x=(-b-√D)/2a
x=(-b+√D)/2a
x=(-8-2√3)/2= (-2(4+√3))/2= -(4+√3)
AND
x=(-8+2√3)/2=-2(4-√3)/2= -(4-√3)
