Answer:
0.60.6
Step-by-step explanation:
AA and BB probability is 0.60.6.
If <5=42 you multiply 5 by 8.4=42
so m <4 is going to be 33.6
4X8.4=33.6
1/4 per hamburger, 4 hamburgers=1 pound 20/4= B. 5 pounds
2x^2+20x = -38
2x^2 + 20x + 38 = 0
Divide both sides by 2.
x^2 + 10x + 19 = 0
The quadratic formula works very well here.
Let a = 1, b = 10 and c = 19
x = [-b +- sqrt{b^2 - 4ac}]/(2a)
Plug those values into the formula to find two answers for x.
One is negative and the other positive.
Good luck.
