600 * 0.85 (the way to work out 85% of something) = 510 flights on time
Answer:
H 16x2–11x
Step-by-step explanation:
4(x2 – 3x) + 12x2 + x
4x^2-12x + 12x^2+x=
16x^2-11x
H 16x2–11x
Now this may or may not be work I’m 99.9 percent sure it’s right but if not sorry
X< -2 means that x must be smaller than -2, so something like -3, -4, -5, etc
The only solution set that fits this is A.
Note that 60 minutes is 1 standard deviation away from the mean and from recalling the 68-95-99.7 rule, the area that will remain is (100 - 68) = 32%. However, we only want the leftmost portion of this area, so the answer is 32%/2 = 16%.
