Answer:
12/20 =3/5
Step-by-step explanation:
4/5 * 3/4 = 12/20 =3/5
Hey, the answer would just be a normal 12. As the answer is a positive it just stays the same!
Hope this helps
I believe the answer is 1/2 because 5 out of 10 of the trials have 0 occurring more than once so the fraction is 5/10= 1/2 so I think you answer should be 1/2
f(x) = (x - 
)² - 
the equation of a quadratic in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
given a quadratic in standard form : y = ax² + bx + c ( a ≠ 0 )
then the x- coordinate of the vertex is
= - 
f(x) = x² - 11x + 9 is in standard form
with a = 1, b = - 11 and c = 9
= - 
=
substitute this value into the equation for y- coordinate
y = ()² - 11() + 9
= 
- 
+ 
= -
f(x) = (x - )² - ← in vertex form
