-1 im not sure if you meant 2x+6x+8=0
C = cost on individual hat, "18 = 3c" would be the equation to describe how much each hat costs. Each hat would cost $6 each.
I think the first part is 10
Answer:
As a fraction, the answer is exactly 86/969
In decimal form, the answer is approximately 0.08875
=====================================================
Work Shown:
The assumption is that no replacements are made for each selection.
5 red, 6 blue, 8 green
5+6+8 = 19 total
A = P(3 red) = (5/19)*(4/18)*(3/17) = 10/969
B = P(3 blue) = (6/19)*(5/18)*(4/17) = 20/969
C = P(3 green) = (8/19)*(7/18)*(6/17) = 56/969
D = P(3 all same color)
D = A+B+C
D = 10/969 + 20/969 + 56/969
D = (10+20+56)/969
D = 86/969
D = 0.08875
Answer:
C
It's between C and D.
But when you closely look at the two answer choices, it is C.
Step-by-step explanation:
In D, the angle AC∠ is too small and it can be automatically crossed out. As well as A and B.
Hope this helped!
