Answer:
-21x^2+50x-24
Step-by-step explanation:
3x((5)(2)-7x+2)-2((5)(2)-7x+2)
30x-21x^2+6x-20+14x-4
50x-21x^2-24
-21x^2+50x-24
Answer:
38.46%
Step-by-step explanation:
There are 91 students and 35 of them received a score of 90 or above.
So, there are 35/91 students with an A grade.
The probability to pick a random student that would be the same proportion that those who got the right score, so 35 / 91 = 0.3846 or 38.46%
38.46% of chances to pick someone who got an A (90 score or above), and, the opposite, 61.54% of chances to pick someone who didn't get an A. That's a strong class!

Angle between 16 and 18 = 90 + 55 = 145°
