So for this question :






Answer:
The discriminant b2−4ac < 0, the equation has no real number solutions, it has complex solutions
Step-by-step explanation:
9x² - 4x + 1 = 0 ax² + bx + c = 0
The discriminant: b² - 4ac = (-4)² - 4*9*1 = 16 - 36 = -20
b2−4ac < 0, the equation has no real number solutions, it has complex solutions
Answer:
1/480
Step-by-step explanation:
<h3>for the 6 sided one</h3>
rolling a 5 is 1/6
<h3>for the 8 sided one</h3>
rolling a 5 is 1/8
<h3>for the 10 sided one</h3>
rolling a 5 is 1/10
total probability= 1/6*1/8*1/10
= 1/480
It's true, just draw the sides and you'll see there's no other angle you could get.
