Answer:
5/16
Step-by-step explanation:
As you can see in the 16 given possible outcomes, in 5 of them at least 3 coins land facing up. Since there are 16 outcomes in total, the probability that at least three coins land facing up is 5/16. Hope this helps!
X=3/2 or 1/2 I think that
Axis of symmerty from form
ax²+bx+c is -b/2a
the axis of symetry is the x value of the vertex so just put the axis of symetry for x an evaluate
4x²-8x-3
-b/2a=-(-8)/(2*4)=8/8=1
input for x
4(1)²-8(1)-3=4-8-3=-7
(1,-7) is vertex
A is answer
It is 0.7 I'm pretty sure but your not being very descriptive
The 4 in that number is in the hundredths section. It means the 4 represents four hundredths
