Answer: 2x2 - 6x - 11
Step-by-step explanation:
1. Evaluate
2. Collect like terms and calculate
3. Reorder the terms
Answer:
2x2-6x-11 ( the second two is above the x)
X = 4, -9
x^2+5x-36=0
1x +5x-36=0
1x (-1x) + 5x (- -1x) -36 = 0
4x - 36 = 0
4 x - 36( - - 36) = 0
4x = -36
4x/4 = -36/4
x= -9
Answer:
The answer would be C. It is 6% higher than the theoretical probability.
519/6=86.5
915/7=130.7142
439/7=62.7142
812/9=90.2222
so i think its the 1st on but i may be wrong.
The answer is 550. Hope this helps!
