Answer:

D

Step-by-step explanation:

  • You have 5 + 6 pencils, which is 11 pencils
  • The probability you will get white is 5/11
  • Prob you get red is 6/11
  • If you pick up a pencil and do not replace it, you now only have 10 pencils left
  • The prob you get a red or a white is dependent on what you picked up first

x^2-6x=-1 If the quadratic equation has real solutions, what are the solutions? Explain. Estimate irrational solutions to the ne
IgorC [24]
X^2 -6x +1 = 0
a=1
b = -6
c = 1

Use the quadratic formula
x = [-b  +- sq root (b^2 -4ac)] / 2a
x = [--6 +- sq root (36 - 4)] / 2
x = [ 6 +- sq root (32)] / 2
sq root (32) = 5.657

x1 = [ 6 + 5.657] / 2
x1 = 11.657 / 2
x1 = <span> <span> <span> 5.8285 </span> </span> </span>
x1 = 5.82 (to nearest tenth)

x2 = [ 6 - 5.657] / 2
x2 = .343 / 2
x2 = .1715
x2 = .2 (to nearest tenth)
